In this article, we would like to show you how to get the last 3 characters from a string in C# / .NET.

Quick solution:

string text = "1234";
string lastCharacters = text.Substring(text.Length - 3);

Console.WriteLine(lastCharacters);  // 234

 

Practical example

The below example shows how to use Substring() method to get the last 3 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(  "123", 3) );  // 123
        Console.WriteLine( getLastCharacters(   "12", 3) );  // 12
        Console.WriteLine( getLastCharacters(    "1", 3) );  // 1
        Console.WriteLine( getLastCharacters(     "", 3) );  //
    }
}

Output:

234
123
12
