C# Split String into array

In C#, we can use String .Split() method, which splits a string into an array of strings, so in this article, I have mentioned few possible ways to use String.Split() method and how we can split string into an array with console application example.

.Split() Method delimiters can be a character or an array of characters or an array of strings. There are around 10 Overloads for String.Split() method. Commonly used are:

• Split(Char[]): Splits a string into substrings based on specified delimiting characters.
• Split(Char, StringSplitOptions): Splits a string into substrings based on a specified delimiting character and, options
• Split(Char[], Int32): First Argument specifies, delimiting character and second one specifies maximum number of substrings.
• Split(String, StringSplitOptions): Splits a string into substrings that are based on the provided string separator.
• Split(Char[], StringSplitOptions): Splits a string into substrings based on specified delimiting characters and options.
• Split(String[], StringSplitOptions): Splits a string into substrings based on the strings in an array.

Split String Into an Array by Comma

Let's a look at an console application example, in which we will split string into array using comma as a delimiter in C#

using System;

namespace StringSplitArray
{
    public class Program
    {
        static void Main(string[] args)
        {
            var names = "Vikram,Vikas,Vinod,Hitesh,Prem";
            //split names string into array
            string[] namesList = names.Split(",");

            //loop and print
            foreach (string name in namesList)
            {
                Console.WriteLine(name);
            }

        }
    }
}

Output:

Vikram
Vikas
Vinod
Hitesh
Prem

Split String By Word

You can also pass a sub-string as an argument to split a string in C# using Split() Method, here is an example of using it in C#

  var str = "Hello This World";
            //split by word
            string[] words = str.Split("This");

            //loop and print
            foreach (string name in words)
            {
                Console.WriteLine(name);
            }

Output:

Hello
 World

Split String by Multiple delimiters

As mentioned above in Split() Overloads, we can pass multiple characters also to split a single string.

Here is an example of using it

            var names = "Vikram,Vikas;Vinod Hitesh;Prem,Pooja";
            //split names string into array
            string[] namesList = names.Split(new char[] {',',' ',';'});

            //loop and print
            foreach (string name in namesList)
            {
                Console.WriteLine(name);
            }

Output:

Vikram
Vikas
Vinod
Hitesh
Prem
Pooja
