How to remove the last n characters of a string in C#

Learn, how can you remove the last n characters from a string in C#.

Consider, we have the following string.

string name = "Yash150";

Now, we want to remove the last 3 characters 150 from the above string.

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, second character is 1 and the last character index is string.Length-1.

Removing the last n characters

To remove the n last characters of a string, we can use the built-in Remove() method by passing the string.Length-n as an argument to it.

n is the number of characters we need to remove from the end of a string.

Here is an example, that removes the last 3 characters 150 from the name string:

using System;
class RemoveCharacters {
  static void Main() {
    string name = "Yash150";
    string result = name.Remove(name.Length-3);
    Console.WriteLine(result);
  }
}

Output:

"Yash"

In the example above, we have passed the startIndex name.Length-3 as an argument to the Remove() method. So it starts removing the characters from that index position to the end of a string and returns the remaining part.

Similarly, we can also use the Substring() method in C# to remove the last n characters of a string.

using System;
class RemoveCharacters {
  static void Main() {
    string name = "Yash150";
    string result = s.Substring(0, s.Length-3);
    Console.WriteLine(result);
  }
}

The string.Length property returns the total number of characters in a given string.

Note: The String.Remove(), Substring() methods returns a new string with the specified characters instead of modifying the original string.
