How to remove first and last character of a string in C#

In this tutorial, we are going to learn about how to remove the first, last character of a string in C#.

Consider, we have the following string.

string s = "play";

Now, we want to remove the first character p, last character y from the above string.

Removing the first and last character

To remove the first and last character of a string, we can use the String.Substring() method by passing the 1, string.Length-2 as an arguments to it.

Note: In C# strings are the sequence of characters that can be accessed by using its character index, where the first character index is 0 and the last character index is a string.Length-1.

Here is an example:

using System;
class RemoveCharacters {
  static void Main() {
    string s = "play";
    string result = s.Substring(1, s.Length-2);
    Console.WriteLine(result);
  }
}

Output:

"la"

In the example above, we have passed 1 , s.Length-2 as arguments to the Substring() method. so it begins the extraction at index position 1 and extracts before the last character position of a string.

Note: The Substring() method returns a new string with the specified characters instead of mutating the original string.
