In this article, we would like to show you how to remove the last 2 characters from the string in C# / .NET.

Quick solution:

xxxxxxxxxx
 
string text = "ABCDE";
​
string result = text[..^2];
Console.WriteLine(result);  // ABC

Practical examples

Edit

1. Using String `Substring()` method

Edit

In this example, we use String Substring() method to create a new result substring from the text string without the last 2 characters.

Syntax:

xxxxxxxxxx
 
Substring (int startIndex, int length);

Note:

If length is not given, substring will be done from startIndex to the end of the text.

Practical example:

xxxxxxxxxx
 
using System;
​
public class StringUtils
{
    public static void Main(string[] args)
    {
        string text = "ABCDE";
​
        string result = text.Substring(0, text.Length - 2);
        Console.WriteLine(result);  // ABC
    }
}

Output:

xxxxxxxxxx
 
ABC

2. Using index from end `^` and range operator `..`

Edit

The range operator .. is used to make a slice of the collection.

Practical example:

xxxxxxxxxx
 
using System;
​
public class StringUtils
{
    public static void Main(string[] args)
    {
        string text = "ABCDE";
​
        string result = text[..^2]; // text[Range.EndAt(new Index(2, fromEnd: true))]
        Console.WriteLine(result);  // ABC
    }
}

Output:

xxxxxxxxxx
 
ABC

3. Using String `Remove()` method

Edit

Syntax:

xxxxxxxxxx
 
Remove (int startIndex, int count);

Practical example:

xxxxxxxxxx
 
using System;
​
public class StringUtils
{
    public static void Main(string[] args)
    {
        string text = "ABCDE";
​
        // Remove last 2 characters
        string result = text.Remove(text.Length - 2);
​
        Console.WriteLine(result);
    }
}
