C# Remove Example Syntax | C-Sharp String Method | Source Code
Purpose: – Illustrates the C# Syntax for Remove.
Step 1: Click on C# to Cut-n-paste code into clsRemove.cs
using System; public class clsRemove { public void Main() { //**************************************************************************************** // Example #1: Remove(startIndex, count) // Returns a string with the specified number of characters removed starting at startIndex. // If no Count is specified, the remainder of string is removed //**************************************************************************************** Console.WriteLine("Example #1: Remove(startIndex, count) "); string strRemoveExample = "This is a test string"; int intIndexRemove = 0; // First find position of word test intIndexRemove = strRemoveExample.IndexOf("test"); // Remove rest of string starting with word "test" Console.WriteLine(strRemoveExample.Remove(intIndexRemove)); //write blank line to make output easier to read Console.WriteLine(); //Prevent console from closing before you press enter Console.ReadLine(); } } |
Step 2: Click on C# to Cut-n-paste code into Program.cs
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace CSharp_Syntax { class Program { static void Main(string[] args) { clsRemove myRemove = new clsRemove(); myRemove.Main(); } } } |
