C# / .NET - get last n characters from string

In this article, we would like to show you how to get the last n characters from a string in C# / .NET.

Quick solution: 

string text = "1234";
int n = 2;
string lastCharacters = text.Substring(text.Length - n);

Console.WriteLine(lastCharacters);  // 34

Practical example

The below example shows how to use Substring() method to get the last n characters from the text string.

using System;

public class StringUtils
{

    public static string getLastCharacters(string text, int charactersCount)
    {
        int length = text.Length;
        int offset = Math.Max(0, length - charactersCount);
        return text.Substring(offset);
    }

    public static void Main(string[] args)
    {
        Console.WriteLine( getLastCharacters( "1234", 3) );  // 234
        Console.WriteLine( getLastCharacters( "1234", 2) );  // 34
        Console.WriteLine( getLastCharacters(   "12", 2) );  // 12
        Console.WriteLine( getLastCharacters(    "1", 2) );  // 1
        Console.WriteLine( getLastCharacters(     "", 2) );  //
    }
}

Output:

234
