因为我更喜欢表达式链语法，下面是你如何做到这一点:

var dealerContracts = DealerContact.Join(Dealer, 
                                 contact => contact.DealerId,
                                 dealer => dealer.DealerId,
                                 (contact, dealer) => contact);

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。

一个最好的例子

表名:TBL_Emp和TBL_Dep

var result = from emp in TBL_Emp join dep in TBL_Dep on emp.id=dep.id
select new
{
 emp.Name;
 emp.Address
 dep.Department_Name
}


foreach(char item in result)
 { // to do}

试试这个吧，

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

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 Join操作符:

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