LINQ的：SELECT DISTINCT和秩序

Question

我有以下....

Dim dc as New DBDataContext 
Dim q = From c In dc.Customers _ 
    Order By c.City _ 
    Select c.City _ 
    Distinct 

我的問題是，雖然查詢產生不同的列表是沒有排序。我如何做到這一點。

Answer 1

如果q您未排序的查詢，那麼你可以事後進行排序它

Dim sorted = From c in q order by c select c 

或

q = From c in q order by c select c 

Answer 2

威爾移動後Distinct修復它Order By c.City？

Dim q = From c In dc.Customers _ 
    Select c.City _ 
    Distinct _ 
    Order By City 

，或者如果以上不工作，你可以在客戶端做排序操作：

Dim result = q.OrderBy(Function(x) x)
