Command-line parameters in WPF application

You can also pass command-line parameters to a WPF application. These will be captured in the Startup event of the App.xaml file. The StartupEventArgs e has a property named Args that returns the command-line parameters as an array of strings.

The following example demonstrates how to retrieve the command-line arguments in WPF application:

    private void Application_Startup(object sender,  
     StartupEventArgs e) 
    { 
      var args = e.Args; 
      if (args != null && args.Count() > 0) 
      { 
        foreach (var arg in args) 
        { 
         // write code to use the command line arg value 
        } 
      } 
    }
