Program that uses optional parameters: C#

using System;

class Program
{
    static void Main()
    {
// Omit the optional parameters.
Method();

// Omit second optional parameter.
Method(4);

// You can't omit the first but keep the second.
// Method("Dot");

// Classic calling syntax.
Method(4, "Dot");

// Specify one named parameter.
Method(name: "Sam");

// Specify both named parameters.
Method(value: 5, name: "Allen");
    }

    static void Method(int value = 1, string name = "Perl")
    {
Console.WriteLine("value = {0}, name = {1}", value, name);
    }
}

Output

value = 1, name = Perl
value = 4, name = Perl
value = 4, name = Dot
value = 1, name = Sam
