How to: Access Command-Line Arguments Using foreach (C# Programming Guide)

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.

Note

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

Example

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
*/
