How to: Get the Command Line Arguments

This example shows how to get the command line arguments that were passed to an application.

The following code demonstrates how to use Application and the Startup event to get the command line arguments.

<Application
    x:Class="CSharp.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Startup="app_Startup"
    >
</Application>
using System;
using System.Windows;

namespace CSharp
{
    public partial class App : Application
    {
        void app_Startup(object sender, StartupEventArgs e)
        {
            // If no command line arguments were provided, don't process them 
            if (e.Args.Length == 0) return;

            // Get command line arguments 
            foreach (string argument in e.Args)
            {
                switch (argument)
                {
                    case "arg1":
                        // Process arg 1 
                        break;
                    case "arg2":
                        // Process arg 2 
                        break;
                    case "arg3":
                        // Process arg 3 
                        break;
                }
            }
        }
    }
}
