Split();

Split(); function in C#
This function is used to split a string into substrings on the basis of characters in an array. It returns a string array. The split method can be implemented by the declaring element inside the separator using a single code(' ')to split from. In the below program I have declared comma sign to split from (','). 

Example
using System;

namespace program

{
    class Program
    {
        static void Main(string[] args)
        {
            string str1 = ("One,Two,Three,Four,Five");
            string[] str2 = str1.Split(',');       /*Declared comma sign to split from (',')*/

            foreach (string str3 in str2)
            {
                Console.WriteLine(str3);
            }  
               Console.ReadKey();        
        }      

    }

 }

Output
One
Two
Three
Four
Five
