What is the use of params keyword? Give an example.

params is used on such situations where the number of arguments to a method is not known until runtime. If you prefix the params keyword followed by the type as array without size, then you can pass as many arguments as you want.


Ex:
using System;
using System.Collections.Generic;
using System.Text;

namespace ParamSample
{
class Program
{
public static void PrintWords(params String[] p)
{
for (int i = 0; i < p.GetLength(0); i++)
{
System.Console.WriteLine(p[i]);
System.Console.Read();
}
}

static void Main(string[] args)
{
PrintWords("1","2","3");
}
}
}
