Remove Method of string in C# Explained

Remove Method of string in C#

The string Remove method is used to delete characters in the string starting from the specified position and continues to the end of the string.

 

In case, if we want to delete a particular length of substring, then we need to specify the starting position and length of characters to delete from the given string.

 

Remove Method Syntax

Following is the syntax for defining a string Remove method to remove characters starting from the defined position in a given string.

 

public string Remove(int startIndex)

public string Remove(int startIndex, int length)

 

Given the above syntaxes, the first syntax is used to delete all the characters in the string, starting from the defined position (startIndex) and the second syntax is used to delete particular length of a substring by defining the starting position and length of characters.

Remove Method Example

The following code snippets is the example of using a string Remove() method to delete characters in string based on the defined position.

 

using System;

namespace CsharpnaijaTutorial

{

    class Program

    {

        static void Main(string[] args)

        {

            string msg = "Welcome to Csharpnaija";

            Console.WriteLine($"Remove Result: {msg.Remove(5)}");

            Console.WriteLine($"Remove with Length: {msg.Remove(3, 7)}");

            Console.WriteLine("\nPress Enter Key to Exit..");

            Console.ReadLine();

        }

    }

}

 

From the above example, we used a string Remove() method to remove a characters starting from the position 5 till the end of defined string and another Remove() method to delete 7 characters starting from the position 3.

 

When you execute the above program, you will get the result as shown below.

 

Remove out

 

From the above result, the string Remove() method has deleted characters based on the defined positions and returned remaining string characters.

 

Thank you
