试试这个:

     var data =(from t1 in dataContext.Table1 join 
                 t2 in dataContext.Table2 on 
                 t1.field equals t2.field 
                 orderby t1.Id select t1).ToList(); 

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);

从d1在dealercontract中加入d2在dealercontract中d1.dealearid = d2.dealerid select new {dealercontract.*}

var data=(from t in db.your tableName(t1) 
          join s in db.yourothertablename(t2) on t1.fieldname equals t2.feldname
          (where condtion)).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。

试试这个:

     var data =(from t1 in dataContext.Table1 join 
                 t2 in dataContext.Table2 on 
                 t1.field equals t2.field 
                 orderby t1.Id select t1).ToList();
