I would like to know how to pragmatically get the name of the running file not the assembly name but the name of the file in C# .NET,

I tried 

System.Reflection.Assembly.GetEntryAssembly().GetName().Name

this gives the name of the assembly but i am looking for the name of the exe file instead.

Thank you!

  • To what end will you use this information? If this is an intermediate step on a solution you've already devised, we may do better knowing what the overall goal is... – Damien_The_Unbeliever Nov 16 '11 at 19:07

 System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName

or

If you want the executable:

System.Reflection.Assembly.GetEntryAssembly().Location

If you'd like just the file*name* and not the path, use:

Path.GetFileName(System.Reflection.Assembly.GetEntryAssembly().Location)

System.Windows.Forms.Application.ExecutablePath

"Gets the path for the executable file that started the application, including the executable name."

If you know your assembly is the EXE in which you are running (which I infer is likely, by the use of "GetEntryAssembly()"), you can use Process.GetCurrentProcess().ProcessName. This will return the name of the EXE for your program.

Look at the first element in this array.

 System.Environment.GetCommandLineArgs()[0];

You can also look at args[0] in main(string args[])

This should change even if the program is renamed.

You can use:

System.Reflection.Assembly.GetExecutingAssembly().Location
