The params keyword provides the facility to specify a method parameter that takes a variable number of arguments. The number of arguments can vary. The following code snippet displays the use of the params keyword:

using System;
public class ParamTest
{
    public static void Main()
   {
       ParamFunc(1,2,3);
       ParamFunc(1,2,3,4,5);
       ParamFunc(1,2,3,4,5,6,7);
    }
    public void ParamFunc(params int[] arrlist)
   {
       foreach(int list in arrlist)
       Console.WriteLine(list);
    }
}
