Another approach to iterating over the array is to use the foreach statement as shown in this example. The foreach statement can be used to iterate over an array, a .NET Framework collection class, or any class or struct that implements the IEnumerable interface.

When running an application in Visual Studio, you can specify command-line arguments in the Debug Page, Project Designer.

This example demonstrates how to print out the command line arguments using foreach.

// arguments: John Paul Mary

    class CommandLine2
    {
        static void Main(string[] args)
        {
            System.Console.WriteLine("Number of command line parameters = {0}", args.Length);

            foreach (string s in args)
            {
                System.Console.WriteLine(s);
            }
        }
    }
    /* Output:
        Number of command line parameters = 3
        John
        Paul
        Mary
    */
