其实很简单。您只需删除“组”：

或者，如果您正在查找lambda语法：

var q = db.Customers.GroupJoin(db.Orders,
                               o => o.CustomerID,
                               c => c.CustomerID,
                               (c, orders) =>
                                   new
                                   {
                                       c.ContactName, 
                                       OrderCount = orders.Count()
                                   });
