Setting Up Octokit.NET in .NET Projects

To begin using Octokit.NET in your projects, you first need to install the package. You can add it via NuGet, which is the easiest method. In Visual Studio, you can use the NuGet Package Manager. Search for Octokit and install it in your project.

A Basic Code Example: Accessing GitHub User Information

Here is a simple example of how to use Octokit.NET to retrieve information about a GitHub user. This example assumes you have already set up your project with Octokit.NET.

using Octokit;
using System;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        // Create a new instance of the GitHubClient class
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        // Retrieve user information
        var user = await client.User.Get("octocat");
        // Output the user's name
        Console.WriteLine("User Name: " + user.Name);
    }
}

using Octokit;
using System;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        // Create a new instance of the GitHubClient class
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        // Retrieve user information
        var user = await client.User.Get("octocat");
        // Output the user's name
        Console.WriteLine("User Name: " + user.Name);
    }
}

Imports Octokit
Imports System
Imports System.Threading.Tasks

Friend Class Program
	Shared Async Function Main(ByVal args() As String) As Task
		' Create a new instance of the GitHubClient class
		Dim client = New GitHubClient(New ProductHeaderValue("YourAppName"))
		' Retrieve user information
		Dim user = Await client.User.Get("octocat")
		' Output the user's name
		Console.WriteLine("User Name: " & user.Name)
	End Function
End Class

This code snippet creates a new GitHub client and retrieves information for a specific user, octocat, by their repository name. It then prints the user's name to the console. It demonstrates authenticated access to GitHub's API, using the user's username, and can also access public repositories without authentication.

Implement Features of Octokit.NET

Searching Repositories

You can search GitHub repositories by criteria using Octokit.NET. Here's how to perform a search:

using Octokit;
using System;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        var searchRepositoriesRequest = new SearchRepositoriesRequest("machine learning")
        {
            Language = Language.CSharp
        };
        var result = await client.Search.SearchRepo(searchRepositoriesRequest);
        foreach (var repo in result.Items)
        {
            Console.WriteLine(repo.FullName);
        }
    }
}

using Octokit;
using System;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        var searchRepositoriesRequest = new SearchRepositoriesRequest("machine learning")
        {
            Language = Language.CSharp
        };
        var result = await client.Search.SearchRepo(searchRepositoriesRequest);
        foreach (var repo in result.Items)
        {
            Console.WriteLine(repo.FullName);
        }
    }
}

Imports Octokit
Imports System
Imports System.Threading.Tasks

Friend Class Program
	Shared Async Function Main(ByVal args() As String) As Task
		Dim client = New GitHubClient(New ProductHeaderValue("YourAppName"))
		Dim searchRepositoriesRequest As New SearchRepositoriesRequest("machine learning") With {.Language = Language.CSharp}
		Dim result = Await client.Search.SearchRepo(searchRepositoriesRequest)
		For Each repo In result.Items
			Console.WriteLine(repo.FullName)
		Next repo
	End Function
End Class

This code searches for repositories related to "machine learning" written in C#. It outputs the full names of the repositories.

Managing Forked Repositories

To manage forked repositories, you can list and create forks. Here's how to list the forks of a repository:

using Octokit;
using System;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        var forks = await client.Repository.Forks.GetAll("octocat", "Hello-World");
        foreach (var fork in forks)
        {
            Console.WriteLine("Fork ID: " + fork.Id + " - Owner: " + fork.Owner.Login);
        }
    }
}

using Octokit;
using System;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        var forks = await client.Repository.Forks.GetAll("octocat", "Hello-World");
        foreach (var fork in forks)
        {
            Console.WriteLine("Fork ID: " + fork.Id + " - Owner: " + fork.Owner.Login);
        }
    }
}

Imports Octokit
Imports System
Imports System.Threading.Tasks

Friend Class Program
	Shared Async Function Main(ByVal args() As String) As Task
		Dim client = New GitHubClient(New ProductHeaderValue("YourAppName"))
		Dim forks = Await client.Repository.Forks.GetAll("octocat", "Hello-World")
		For Each fork In forks
			Console.WriteLine("Fork ID: " & fork.Id & " - Owner: " & fork.Owner.Login)
		Next fork
	End Function
End Class

This example lists all forks of the "Hello-World" repository owned by octocat.

Handling Rate Limits

Understanding and handling rate limits is crucial when interacting with the GitHub API. Octokit.NET provides tools to check your rate limits:

using Octokit;
using System;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        var rateLimit = await client.Miscellaneous.GetRateLimits();
        Console.WriteLine("Core Limit: " + rateLimit.Resources.Core.Limit);
    }
}

using Octokit;
using System;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        var rateLimit = await client.Miscellaneous.GetRateLimits();
        Console.WriteLine("Core Limit: " + rateLimit.Resources.Core.Limit);
    }
}

Imports Octokit
Imports System
Imports System.Threading.Tasks

Friend Class Program
	Shared Async Function Main(ByVal args() As String) As Task
		Dim client = New GitHubClient(New ProductHeaderValue("YourAppName"))
		Dim rateLimit = Await client.Miscellaneous.GetRateLimits()
		Console.WriteLine("Core Limit: " & rateLimit.Resources.Core.Limit)
	End Function
End Class

This snippet checks and displays the core limit of your GitHub API usage, helping you manage the requests without exceeding the rate limits.

Reactive Extensions Support

Octokit.NET supports Reactive Extensions (Rx) for reactive programming. Here's a basic example:

using Octokit.Reactive;
using System;

var client = new ObservableGitHubClient(new ProductHeaderValue("YourAppName"));
var subscription = client.User.Get("octocat").Subscribe(
    user => Console.WriteLine("User Name: " + user.Name),
    error => Console.WriteLine("Error: " + error.Message)
);
// Unsubscribe when done
subscription.Dispose();

using Octokit.Reactive;
using System;

var client = new ObservableGitHubClient(new ProductHeaderValue("YourAppName"));
var subscription = client.User.Get("octocat").Subscribe(
    user => Console.WriteLine("User Name: " + user.Name),
    error => Console.WriteLine("Error: " + error.Message)
);
// Unsubscribe when done
subscription.Dispose();

Imports Octokit.Reactive
Imports System

Private client = New ObservableGitHubClient(New ProductHeaderValue("YourAppName"))
Private subscription = client.User.Get("octocat").Subscribe(Sub(user) Console.WriteLine("User Name: " & user.Name), Sub([error]) Console.WriteLine("Error: " & [error].Message))
' Unsubscribe when done
subscription.Dispose()

This example demonstrates how to asynchronously retrieve user information and handle it reactively.

Working with Tags

To work with Git tags through Octokit.NET, you can retrieve tags from a repository:

using Octokit;
using System;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        var tags = await client.Repository.GetAllTags("octocat", "Hello-World");
        foreach (var tag in tags)
        {
            Console.WriteLine("Tag Name: " + tag.Name);
        }
    }
}

using Octokit;
using System;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        var tags = await client.Repository.GetAllTags("octocat", "Hello-World");
        foreach (var tag in tags)
        {
            Console.WriteLine("Tag Name: " + tag.Name);
        }
    }
}

Imports Octokit
Imports System
Imports System.Threading.Tasks

Friend Class Program
	Shared Async Function Main(ByVal args() As String) As Task
		Dim client = New GitHubClient(New ProductHeaderValue("YourAppName"))
		Dim tags = Await client.Repository.GetAllTags("octocat", "Hello-World")
		For Each tag In tags
			Console.WriteLine("Tag Name: " & tag.Name)
		Next tag
	End Function
End Class

This code lists all tags for the "Hello-World" repository owned by octocat.

Integrating Octokit.NET with IronPDF

Octokit .NET (How It Works For Developers): Figure 1 - IronPDF

IronPDF is a popular .NET library that allows developers to create, manipulate, and render PDFs directly within C# and .NET applications. It's a powerful tool for generating PDF reports from HTML, invoices, or any document that needs a fixed layout format. When combined with Octokit.NET, which interacts with GitHub's API, the potential for automating documentation processes, especially involving code repositories, increases significantly.

Use Case of Merging IronPDF with Octokit.NET

One practical use case for integrating IronPDF with Octokit.NET is automatically generating a PDF report of a project's documentation stored in a GitHub repository. For instance, you could fetch all markdown files from a specific repository, convert them into a PDF document, and then distribute this document among stakeholders or customers who might prefer a compiled version of documentation or release notes.

Code Example of Use Case

Let's create a simple application that demonstrates this integration. The application will perform the following tasks:

Authenticate and connect to GitHub using Octokit.NET.
Fetch files from a specified repository.
Convert these files from Markdown to PDF using IronPDF.
Save the PDF to the local machine.

Here's how you might write this in C#:

using Octokit;
using IronPdf;
using System;
using System.Threading.Tasks;
using System.Linq;

class Program
{
    static async Task Main(string[] args)
    {
        // GitHub client setup
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        var tokenAuth = new Credentials("your_github_token"); // Replace with your GitHub token
        client.Credentials = tokenAuth;
        // Repository details
        var owner = "repository_owner";
        var repo = "repository_name";
        // Fetch repository content
        var contents = await client.Repository.Content.GetAllContents(owner, repo);
        // Initialize the PDF builder
        var pdf = new ChromePdfRenderer();
        // Convert each markdown file to PDF
        foreach (var content in contents.Where(c => c.Name.EndsWith(".md")))
        {
            pdf.RenderHtmlAsPdf(content.Content).SaveAs($"{content.Name}.pdf");
            Console.WriteLine($"Created PDF for: {content.Name}");
        }
    }
}

using Octokit;
using IronPdf;
using System;
using System.Threading.Tasks;
using System.Linq;

class Program
{
    static async Task Main(string[] args)
    {
        // GitHub client setup
        var client = new GitHubClient(new ProductHeaderValue("YourAppName"));
        var tokenAuth = new Credentials("your_github_token"); // Replace with your GitHub token
        client.Credentials = tokenAuth;
        // Repository details
        var owner = "repository_owner";
        var repo = "repository_name";
        // Fetch repository content
        var contents = await client.Repository.Content.GetAllContents(owner, repo);
        // Initialize the PDF builder
        var pdf = new ChromePdfRenderer();
        // Convert each markdown file to PDF
        foreach (var content in contents.Where(c => c.Name.EndsWith(".md")))
        {
            pdf.RenderHtmlAsPdf(content.Content).SaveAs($"{content.Name}.pdf");
            Console.WriteLine($"Created PDF for: {content.Name}");
        }
    }
}

Imports Octokit
Imports IronPdf
Imports System
Imports System.Threading.Tasks
Imports System.Linq

Friend Class Program
	Shared Async Function Main(ByVal args() As String) As Task
		' GitHub client setup
		Dim client = New GitHubClient(New ProductHeaderValue("YourAppName"))
		Dim tokenAuth = New Credentials("your_github_token") ' Replace with your GitHub token
		client.Credentials = tokenAuth
		' Repository details
		Dim owner = "repository_owner"
		Dim repo = "repository_name"
		' Fetch repository content
		Dim contents = Await client.Repository.Content.GetAllContents(owner, repo)
		' Initialize the PDF builder
		Dim pdf = New ChromePdfRenderer()
		' Convert each markdown file to PDF
		For Each content In contents.Where(Function(c) c.Name.EndsWith(".md"))
			pdf.RenderHtmlAsPdf(content.Content).SaveAs($"{content.Name}.pdf")
			Console.WriteLine($"Created PDF for: {content.Name}")
		Next content
	End Function
End Class

In this example, after setting up the GitHub client and specifying your credentials, you fetch content from a repository. For each markdown file in the repository, IronPDF converts the content to a PDF file, which is then saved locally. This simple yet effective workflow can be expanded to include more complex filtering, formatting, or even batch processing of files for larger repositories.
