Solution 2

Yes, We make our class property as primary key.
To make the class property as primary key we have to use the following name space:
using System.Data.LINQ.Mapping;
Then we can map our class according to the table.

public class Employee
[Coloumn(IsPrimaryKey=true,Storage="ID", Name="_id")]
public int Id{get;set;}

Thus we can set our class property according to the related Table field.

Thus I can solve.
