C# Open File With Associated Application passing arguments

Question

I am trying to launch the default application registered for an extension specifying an additional argument:

 ProcessStartInfo p = new ProcessStartInfo();
          


        

Answer 1

I think an easier method is using the cmd command

 void LaunchAssociatedProgram(string filename) {
     Process.Start( @"cmd.exe", "/C start "+ filename );
 }

EDIT:

I don't know if it works with arguments, but it is what I was looking for to launch an associated program...
