How to get the last character of a string in C#

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

Consider, we have the following string.

string str = "piano";

Now, we want to get the last character o from the above string.

Getting the last character

To access the last character of a string, we can use the subscript syntax [] by passing the str.Length-1 which is the index of the last character.

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.

Here is an example, that gets the last character o from the following string:

using System;
class StringCharacter {
  static void Main() {
    string str = "piano";
    char lastCharacter = str[str.Length-1];
    Console.WriteLine(lastCharacter);
  }
}

Output:

"o"

Similarly, we can also use the Substring() method in C# to get the last character of a string like this.

using System;
class StringCharacter {
  static void Main() {
    String str = "piano";
    string lastCharacter = str.Substring(str.Length-1);
    Console.WriteLine(lastCharacter);
  }
}

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