How to remove an object with specific property value from the List of Objects using LINQ

Suppose you have an object call Employee (having properties EmployeeID and EmployeeName) and you have List of Employee object (List lstEmployee, now if you want to remove a particular Employee object which has EmployeeID lets say 10 from the list lstEmployee, below is the source code which will give some feel of LINQ.

using System;

using System.Configuration;

using System.Data;

using System.Linq;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.HtmlControls;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Xml.Linq;

using System.Collections.Generic;

public partial class _Default : System.Web.UI.Page


class Employee


public int EmployeeId { get; set; }

public string EmployeeName { get; set; }


protected void Page_Load(object sender, EventArgs e)


List<Employee> lstEmployee = new List<Employee>();

Employee emp = new Employee();

emp.EmployeeId = 1;

emp.EmployeeName = "Name1";


emp = new Employee();

emp.EmployeeId = 2;

emp.EmployeeName = "Name2";


emp = new Employee();

emp.EmployeeId = 10;

emp.EmployeeName = "Name10";


//Below LINQ is used to get all the employee which is not having employee id 10

lstEmployee = lstEmployee.Where(x => x.EmployeeId != 10).ToList();



Happy Coding !!!!!!!
