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

  • Article

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
*/
