Linq用于映射表

Question

I dont know how to write linq for the given scenario. Any help please?

I have three tables

1. Employee ( have empid, name etc,)
2. Role (have roleid, rolename etc.,)
3. EmpRoleMapping(have roleid,empid)

I need a query to get the employeeName from employeetable and rolename from role table.

Any help please?

I am generating the mapping table in using entity framework like below, i am not getting the third table name, now to get the name of the table for writing the linq

  modelBuilder.Entity<Employee>()
                .HasMany(role => role.Roles)
                .WithMany(emp => emp.employee)
                .Map(role => role.MapLeftKey("RoleId").MapRightKey("EmployeeId").ToTable("EmployeeRoleMapping"));

Answer 1

var query = from emp in db.Employee
            join empRole in db.EmpRoleMapping
            on emp.empid equals empRole.empid
            join r in db.Role 
            on empRole.roleid equals r.roleid
            select new { employeeName = emp.name, rolename = r.rolename };

Answer 2

我猜这：

var result = employee.Select(e => e.name, e.Role.rolename);
