在linqc#内连接两个表

var result = from q1 in table1
             join q2 in table2
             on q1.Customer_Id equals q2.Customer_Id
             select new { q1.Name, q1.Mobile, q2.Purchase, q2.Dates }

使用LINQ连接执行内部连接。

var employeeInfo = from emp in db.Employees
                   join dept in db.Departments
                   on emp.Eid equals dept.Eid 
                   select new
                   {
                    emp.Ename,
                    dept.Dname,
                    emp.Elocation
                   };

使用Linq Join操作符:

var q =  from d in Dealer
         join dc in DealerConact on d.DealerID equals dc.DealerID
         select dc;

试试这个吧，

var dealer = from d in Dealer
             join dc in DealerContact on d.DealerID equals dc.DealerID
             select d;

var Data= (from dealer in Dealer join dealercontact in DealerContact on dealer.ID equals dealercontact.DealerID
select new{
dealer.Id,
dealercontact.ContactName

}).ToList();

它是这样的:

from t1 in db.Table1
join t2 in db.Table2 on t1.field equals t2.field
select new { t1.field2, t2.field3}

为了更好的示例，最好为您的表提供合理的名称和字段。：）

更新

我认为对于你的疑问，这可能更合适:

var dealercontacts = from contact in DealerContact
                     join dealer in Dealer on contact.DealerId equals dealer.ID
                     select contact;

既然你要找的是联系人，而不是经销商。
