Exit a loop early in C#

To exit the foreach earlier than it suppose to be we have to use the break statement. By using the break statement, it terminates the closest enclosing loop or switch statement.

Please see the example below. The statements below is an example of a search algorithm where the loop terminates as soon as it found the search item on the list.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace TestSolution
{
    public partial class ForeachBreak : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            //creates list of string data
            List lst = new List();
            lst.Add("anna");
            lst.Add("jun");
            lst.Add("sam");
            lst.Add("leila");

            //set search item to search to the list
            string searchItem = "jun";
            
            //flag to know that the item been seached exist or not
            bool isFound = false;

            foreach (string s in lst)
            {
                if (s.Equals(searchItem))
                {
                    isFound = true;
                    break; 
                }
            }

            //show the result
            Response.Write(isFound);

        }
    }
}
