Convert html url to pdf

Hello,

You can do using below code,

using System;
using System.IO;
using System.Net;

class Program
{
    static void Main(string[] args)
    {
        string url = "http://example.com"; // Replace with your URL
        string tempHtmlFile = Path.Combine(Path.GetTempPath(), "temp.html");
        string pdfFilePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "output.pdf");

      
        using (WebClient webClient = new WebClient())
        {
            webClient.DownloadFile(url, tempHtmlFile);
        }

       
        string wkhtmltopdfPath = @"C:\path\to\wkhtmltopdf.exe";
        System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo()
        {
            FileName = wkhtmltopdfPath,
            Arguments = $"\"{tempHtmlFile}\" \"{pdfFilePath}\"",
            UseShellExecute = false,
            CreateNoWindow = true,
        };

        using (var process = System.Diagnostics.Process.Start(startInfo))
        {
            process.WaitForExit();
        }

        File.Delete(tempHtmlFile);

        Console.WriteLine("PDF created at: " + pdfFilePath);
    }
}

To convert HTML from a URL to a PDF in C# without using third-party controls, you can utilize the built-in capabilities of the .NET framework along with the System.Net and System.IO namespaces. Below is a simple approach using the WebClient class to fetch the HTML content and the PdfSharp library, which is included in .NET Core.

using System;
using System.IO;
using System.Net;
using PdfSharp.Pdf;
using PdfSharp.Drawing;

class Program
{
    static void Main()
    {
        string url = "http://example.com";
        string htmlContent = GetHtml(url);
        ConvertHtmlToPdf(htmlContent, "output.pdf");
    }

    static string GetHtml(string url)
    {
        using (WebClient client = new WebClient())
        {
            return client.DownloadString(url);
        }
    }

    static void ConvertHtmlToPdf(string html, string outputPath)
    {
        PdfDocument document = new PdfDocument();
        document.Info.Title = "Converted PDF";

        PdfPage page = document.AddPage();
        XGraphics gfx = XGraphics.FromPdfPage(page);
        XFont font = new XFont("Verdana", 20, XFontStyle.Bold);
        gfx.DrawString(html, font, XBrushes.Black, new XRect(0, 0, page.Width, page.Height), XStringFormats.TopLeft);

        document.Save(outputPath);
    }
}
