Linq從C＃到VB的查詢轉換：NET

Question

我需要轉換Linq Query的幫助。我已經上線試的轉換工具，但沒有運氣... 查詢是這樣的：

var orderedData =(from d in collezione 
       group d by d.Gruppo into g 
       orderby g.Key 
       from d in g 
select new[] {d}.Union(g.Where(c => c.Owner == d.Comp)) into withChildren 
          from wc in withChildren 
          orderby wc.Pos 
          select wc).Distinct(); 

Answer 1

我不知道這是否是你所需要的（這是一個隨意的出手，因爲你的問題是不完整）：

Dim orderedData = From d In collezione 
        Order By d.Gruppo 
        Group d By d.Gruppo Into g = Group 
        From d In g 
        Select New With { 
         .withChildren = {d}. 
          Union(g.Where(Function(c) c.Owner = d.Comp)) 
        } 
Dim result = (From od In orderedData 
       From wc In od.withChildren 
       Order By wc.Pos 
       Select wc).Distinct
