如何用 C# 寫 PDF 轉換器

using IronPdf;

class Program
{
    static void Main(string[] args)
    {
        // HTML content to convert
        string html = "<h1>This Document was Converted using IronPDF</h1><p>This document was converted from HTML content</p>";

        // Instantiate the ChromePdfRenderer class
        ChromePdfRenderer renderer = new ChromePdfRenderer();

        // Render the HTML content into a PDF document
        PdfDocument pdf = renderer.RenderHtmlAsPdf(html);

        // Save the rendered PDF document to a file
        pdf.SaveAs("html-to-pdf.pdf");
    }
}

using System;
using IronPdf;

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

        // Render the URL content into a PDF
        PdfDocument pdf = renderer.RenderUrlAsPdf("https://www.nuget.org/packages/IronPdf/");

        // Save the PDF to a file
        pdf.SaveAs("url-to-pdf.pdf");
    }
}

using System.Collections.Generic;
using IronPdf;

class Program
{
    static void Main(string[] args)
    {
        // Define image file paths
        string jpgFile = "image-jpg.jpg";
        string pngFile = "image-png.png";
        string gifFile = "image-gif.gif";

        // Convert each image to a separate PDF document
        PdfDocument pdfA = ImageToPdfConverter.ImageToPdf(gifFile);
        PdfDocument pdfB = ImageToPdfConverter.ImageToPdf(pngFile);
        PdfDocument pdfC = ImageToPdfConverter.ImageToPdf(jpgFile);

        // Combine all the PDFs into a single document
        List<PdfDocument> pdfFiles = new List<PdfDocument> { pdfA, pdfB, pdfC };
        PdfDocument mergedPdf = PdfDocument.Merge(pdfFiles);

        // Save the merged PDF document to a file
        mergedPdf.SaveAs("images-to-pdf.pdf");
