LINQ Distinct not work [Resolved]

Hi All,

  List<ClsEmployees> objEmployee = new List<ClsEmployees>
            {
                new ClsEmployees { EmpID = "1001" ,Name ="GANTEC", Salary =10000 },
                new ClsEmployees { EmpID = "1002" ,Name ="IBM", Salary =15000 },
                new ClsEmployees { EmpID = "1003" ,Name ="CTS", Salary =20000 },
                new ClsEmployees { EmpID = "1004" ,Name ="WIPRO", Salary =30000 },
                new ClsEmployees { EmpID = "1005" ,Name ="SATHYAM", Salary =40000 },
                new ClsEmployees { EmpID = "1006" ,Name ="BUTTERFLY", Salary =50000 },
                new ClsEmployees { EmpID = "1007" ,Name ="CON", Salary =10000 },
                new ClsEmployees { EmpID = "1008" ,Name ="TVS", Salary =75000 },
                 new ClsEmployees { EmpID = "1008" ,Name ="TVS", Salary =75000 },
                new ClsEmployees { EmpID = "1010" ,Name ="TATA", Salary =90000 },
                 new ClsEmployees { EmpID = "1009" ,Name ="GANTEC COR", Salary =100000 },
                  new ClsEmployees { EmpID = "1009" ,Name ="GANTEC COR", Salary =100000 },
                };

Query for Distinct:

var dis = (from emp in objEmployee select emp).Distinct();
                    dataGridView1.DataSource = dis.ToList();

It doesn't work .Why?
