How to get substring from a string in C#?

Here, we will learn how to get substring from a given string using C# program? To get substring from a string there is a method of string class String.SubString() which takes starting index and total number of characters (length) to get.

Given a string and we have to get the substring of N characters.

For Example: Input string is "India is great country" and we want to extract the substring (5 characters ) from 9th index, which will be "great".


String.Substring() Method returns the given number of characters (length) from given starting position (index).


String String.Substring(int index, int length );

index – is the starting indexing from where you want to extract the substring (indexing starts from 0).
length – is the total number of characters to be extracted.
Return type String – method will return the length characters from index (substring), which will be the result.

Consider the program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
    class Program
        static void Main()
            String str1;
            String str2;

            Console.Write("Enter string : ");
            str1 = Console.ReadLine();

            str2 = str1.Substring(9, 5);
            Console.WriteLine("Sub string is: " + str2);


Enter string : India is great country.
Sub string is: great
