How do I get the name of the current executable in

Question

I want to get the name of the currently running program, that is the executable name of the program. In C/C++ you get it from args[0].

Answer 1

IF you are looking for the full path information of your executable, the reliable way to do it is to use the following:

   var executable = System.Diagnostics.Process.GetCurrentProcess().MainModule
                       .FileName.Replace(".vshost", "");

This eliminates any issues with intermediary dlls, vshost, etc.

Answer 2

Super easy, here:

Environment.CurrentDirectory + "\\" + Process.GetCurrentProcess().ProcessName

Answer 3

Try Application.ExecutablePath

Answer 4

You can use Environment.GetCommandLineArgs() to obtain the arguments and Environment.CommandLine to obtain the actual command line as entered.

Also, you can use Assembly.GetEntryAssembly() or Process.GetCurrentProcess().

However, when debugging, you should be careful as this final example may give your debugger's executable name (depending on how you attach the debugger) rather than your executable, as may the other examples.

Answer 5

System.Diagnostics.Process.GetCurrentProcess() gets the currently running process. You can use the ProcessName property to figure out the name. Below is a sample console app.

using System;
using System.Diagnostics;

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(Process.GetCurrentProcess().ProcessName);
        Console.ReadLine();
    }
}

Answer 6

When uncertain or in doubt, run in circles, scream and shout.

class Ourself
{
    public static string OurFileName() {
        System.Reflection.Assembly _objParentAssembly;

        if (System.Reflection.Assembly.GetEntryAssembly() == null)
            _objParentAssembly = System.Reflection.Assembly.GetCallingAssembly();
        else
            _objParentAssembly = System.Reflection.Assembly.GetEntryAssembly();

        if (_objParentAssembly.CodeBase.StartsWith("http://"))
            throw new System.IO.IOException("Deployed from URL");

        if (System.IO.File.Exists(_objParentAssembly.Location))
            return _objParentAssembly.Location;
        if (System.IO.File.Exists(System.AppDomain.CurrentDomain.BaseDirectory + System.AppDomain.CurrentDomain.FriendlyName))
            return System.AppDomain.CurrentDomain.BaseDirectory + System.AppDomain.CurrentDomain.FriendlyName;
        if (System.IO.File.Exists(System.Reflection.Assembly.GetExecutingAssembly().Location))
            return System.Reflection.Assembly.GetExecutingAssembly().Location;

        throw new System.IO.IOException("Assembly not found");
    }
}

I can't claim to have tested each option, but it doesn't do anything stupid like returning the vhost during debugging sessions.
