C# program to remove characters starting at a particular index in StringBuilder

Set StringBuilder −

StringBuilder str = new StringBuilder("Airport");

Let’s say you need to remove characters. For that, use the Remove() method, which removes a bunch of characters beginning with a particular index −

str.Remove(3, 4);

The above removes four characters beginning from 3rd index (i.e. 4th position) −

Here is the complete code −

Example

 Live Demo

using System; using System.Text; public class Program {    public static void Main() {       StringBuilder str = new StringBuilder("Airport");       Console.WriteLine("String: "+str);       // removing four characters       Console.Write("String after removing characters: ");       str.Remove(3, 4);       Console.WriteLine(str);    } }

Output

String: Airport String after removing characters: Air
