Problem

How to convert Html file to PDF using command line from code behind c# (The use of Bat file for executing the cmd command)

Environment

Visual Studio 2019, .Net 4.6.1, C#, Console Application

How you fix it

With the help of Command line and by creating a bat file, the cmd command can be executed successfully. The conversion can be achieved by executing command using headless chrome and the command is basically used to execute chrome exe.

Solution

First you need to create a .bat file and add the following cmd command in that bat file

"c:/Program Files/Google/Chrome/Application/chrome.exe" --headless --disable-gpu --print-to-pdf=%2 %1
rem "c:/Program Files/Google/Chrome/Application/chrome.exe" --headless --disable-gpu --print-to-pdf=c:/temp/123.pdf c:/temp/8896635555.html

Now, use the below method to execute the bat file using cmd.

private void GeneratePDFFILE(string Cr, string HtmlFilePath, string BatFilePath, string PDFOutPath)
{
    METHOD_NAME = "[M360Controller => GeneratePDFFILE]";

    Log4Bayan.Log(String.Format("{0} {1}", METHOD_NAME, Execution_Started) + " For PDF Generation", Info);

    string commandToExecute = "" + BatFilePath + "HtmlToPdf.bat " + HtmlFilePath + Cr + ".html " + PDFOutPath + Cr + ".pdf";

    Process.Start(@"cmd", @"/c " + commandToExecute);

}
