Linq Getting distinct values from a custom list

In this article we are going to see how to get the distinct values from a list of data. Here we are using a list of employees and displaying the distinct names of employee from the list. We are going to use Linq to get the distinct values.

1.Create an Employee class with EmpId,EmpName and Course datamembers as shown below:

public class Employee
{
	public Employee()
	{
	}
    public Employee(int id,string name,string courseName)
    {
        this.EmpId = id;
        this.EmpName = name;
        this.Course = courseName;
    }

    private int empId;

    public int EmpId
    {
        get { return empId; }
        set { empId = value; }
    }
    private string empName;

    public string EmpName
    {
        get { return empName; }
        set { empName = value; }
    }
    private string course;

    public string Course
    {
        get { return course; }
        set { course = value; }
    }
}

using System.Linq;

       List lstEmployee = new List();
        lstEmployee.Add(new Employee(1, "rohit", ".Net"));
        lstEmployee.Add(new Employee(2, "rohit", "Java"));
        lstEmployee.Add(new Employee(3, "Akansha", ".Net"));
        lstEmployee.Add(new Employee(4, "Teena", "Java"));
        lstEmployee.Add(new Employee(5, "rohit", "Oracle"));

List lstEmp =
(from empnames in lstEmployee.AsEnumerable()
select new{
     Name = empnames.EmpName
          }).Distinct().Select(x =>new Employee() 
                { EmpName = x.Name }).ToList();

foreach (Employee emp in lstEmp)
{
  Response.Write(emp.EmpName + "  ");
}
