C# / .NET - replace last 2 characters in string
0 points
In this article, we would like to show you how to replace last 2 characters in string in C# / .NET.
Quick solution:
xxxxxxxxxx1
string text = "ABC";2
string replacement = "12";3
string result = text[0..^2] + replacement;4
5
Console.WriteLine(result); // A12
In this example, we use the range operator .., which is an alternative to Substring() method to removing the last 2 characters from the text string, then we add the replacement at their place.
xxxxxxxxxx1
using System;2
3
public class StringUtils4
{5
public static void Main(string[] args)6
{7
string text = "ABC";8
string replacement = "12";9
string result = text[0..^2] + replacement;10
11
Console.WriteLine("Original string: " + text); // ABC12
Console.WriteLine("Modified string: " + result); // A1213
}14
}Output:
xxxxxxxxxx1
Original string: ABC2
Modified string: A12Note:
The
replacementlength doesn't have to be equal to 2. You can remove the last 2 characters from the end of the string and add any number of characters instead.
