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

In this tutorial, we are going to learn about how to get the last n number of characters from a string in C#

Getting the last n characters

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

Where -n is the number of characters we need to get from the end of a string.

Here is an example, that gets the last 3 characters from a name string:

string name = "pearson";
string lastThree =  name.Substring(name.Length-3);

Console.WriteLine(lastThree);

Output:

son

In the example above, we have passed name.Length-3 as arguments to the Substring() method. So it starts the extraction at index position name.Length-3, and extract the rest of a string.
