C# Data Types (How it Works For Developers)

Numeric Types

int number = 100;
short smallNumber = 200;
long largeNumber = 300L;
byte positiveNumber = 255;
sbyte negativeNumber = -100;

int number = 100;
short smallNumber = 200;
long largeNumber = 300L;
byte positiveNumber = 255;
sbyte negativeNumber = -100;

float floatValue = 10.5f;
double doubleValue = 20.55;

float floatValue = 10.5f;
double doubleValue = 20.55;

decimal money = 100.50m;

decimal money = 100.50m;

Textual Types

char letter = 'A';

char letter = 'A';

string name = "John";

string name = "John";

Other Predefined Types

bool isTrue = true;

bool isTrue = true;

object obj = "This is a string";

object obj = "This is a string";

dynamic anything = 10;

dynamic anything = 10;

Predefined Reference Types

Aside from the above-mentioned value types, there are predefined reference types, including:

• Class Types: Defines the blueprint of an object.
• Interface Types: Defines a contract that classes can implement.
• Array Types: Enables the creation of an array, a collection of items of the same type.

Built-in Conversions

C# also provides built-in conversions between different predefined data types. For example, you can convert an int to a float without losing information.

Default Values

Each value data type has a default value that gets assigned if no value is given. For example, the default value of a bool data type is false, while for reference types, it's null.

Struct Types

Useful for small data structures. It allows you to group different data types under a single variable name. It can be defined in C# as follows:

public struct Point
{
    public int X;
    public int Y;
}

public struct Point
{
    public int X;
    public int Y;
}

Enum Types

An enumeration is a set of named constants representing underlying integral values.

enum Days { Sun, Mon, Tue, Wed, Thu, Fri, Sat }

enum Days { Sun, Mon, Tue, Wed, Thu, Fri, Sat }

User Defined Reference Types

Class Types, Interface Types, Array Types, and Delegate Types: These are reference types and more advanced but equally essential.

• Class types: Allow you to encapsulate data and methods within a single unit.
• Interface Types: Define a set of methods that a class type must implement. It's like a guideline to how a class type should be built.
• Array Types: A data structure that stores a fixed size collection of elements of the same data type.
• Delegate types: A type that represents a reference to a method.

IronPDF Your Solution for PDF Operations

IronPDF Tool for PDF Manipulation in C# is an indispensable tool when you need to work with PDF documents in your C# projects. This tool can generate PDFs from HTML, images, and ASPX web forms. This can be seen as analogous to working with string data types in C#.

IronPDF is a really awesome tool that can turn webpages, URLs, and HTML into PDFs that look exactly like the original. This is perfect for creating PDFs of online stuff like reports and invoices. So, if you ever need to make a PDF from a webpage, IronPDF is the way to go!

using IronPdf;

class Program
{
    static void Main(string[] args)
    {
        var renderer = new ChromePdfRenderer();

        // 1. Convert HTML String to PDF
        var htmlContent = "<h1>Hello, IronPDF!</h1><p>This is a PDF from an HTML string.</p>";
        var pdfFromHtmlString = renderer.RenderHtmlAsPdf(htmlContent);
        pdfFromHtmlString.SaveAs("HTMLStringToPDF.pdf");

        // 2. Convert HTML File to PDF
        var htmlFilePath = "path_to_your_html_file.html"; // Specify the path to your HTML file
        var pdfFromHtmlFile = renderer.RenderHtmlFileAsPdf(htmlFilePath);
        pdfFromHtmlFile.SaveAs("HTMLFileToPDF.pdf");

        // 3. Convert URL to PDF
        var url = "http://ironpdf.com"; // Specify the URL
        var pdfFromUrl = renderer.RenderUrlAsPdf(url);
        pdfFromUrl.SaveAs("URLToPDF.pdf");
    }
}

using IronPdf;

class Program
{
    static void Main(string[] args)
    {
        var renderer = new ChromePdfRenderer();

        // 1. Convert HTML String to PDF
        var htmlContent = "<h1>Hello, IronPDF!</h1><p>This is a PDF from an HTML string.</p>";
        var pdfFromHtmlString = renderer.RenderHtmlAsPdf(htmlContent);
        pdfFromHtmlString.SaveAs("HTMLStringToPDF.pdf");

        // 2. Convert HTML File to PDF
        var htmlFilePath = "path_to_your_html_file.html"; // Specify the path to your HTML file
        var pdfFromHtmlFile = renderer.RenderHtmlFileAsPdf(htmlFilePath);
        pdfFromHtmlFile.SaveAs("HTMLFileToPDF.pdf");

        // 3. Convert URL to PDF
        var url = "http://ironpdf.com"; // Specify the URL
        var pdfFromUrl = renderer.RenderUrlAsPdf(url);
        pdfFromUrl.SaveAs("URLToPDF.pdf");
    }
}
