The best way is not to modify the arguments at runtime but to debug an instance that has the arguments you want.

For Windows you can do this in Visual Studio as follows:

  • Right click on project in Solution Explorer.
  • Set the arguments you want in Configuration Properties -> Debugging -> Command Arguments.
  • Hit F5 to start the program (after setting breakpoints where you want to stop).

Alternatively start the program up as normal from the command line, and attach the debugger afterwards.
