のLINQのC＃からVB.net

Question

に私はC＃のこのLINQの式からattempingんだけど、

C＃

var v = (from a in dc.ChatPrivateMessageMasters 
        join b in dc.ChatPrivateMessageDetails on a.EmailID equals b.MasterEmailID into cc 
        from c in cc 
        where (c.MasterEmailID.Equals(fromid) && c.ChatToEmailID.Equals(toid)) || (c.MasterEmailID.Equals(toid) && c.ChatToEmailID.Equals(fromid)) 
        orderby c.ID descending 
        select new 
        { 
         UserName = a.UserName, 
         Message = c.Message, 
         ID = c.ID 
        }).Take(take).ToList(); 

VB

Dim v = (From a In dc.ChatPrivateMessageMasters _ 
Join b In dc.ChatPrivateMessageDetails On a.EmailID Equals b.MasterEmailID _ 
Into cc _ 
From c In cc Where (c.MasterEmailID.Equals(fromid) AndAlso c.ChatToEmailID.Equals(toid)) OrElse (c.MasterEmailID.Equals(toid) AndAlso c.ChatToEmailID.Equals(fromid)) _ 
Order By c.ID Descending _ 
Select New With { _ 
    .UserName = a.UserName, _ 
    .Message = c.Message, _ 
    .ID = c.ID _ 
}).Take(take).ToList() 

を動作していないよう

私が受け取りました'Into'のエラーメッセージ： '）'が返されます

//あなたが参加するグループを必要としない、手始めに

私のデータベース構造更新（あなたjoin句のinto一部）は、あなたはすぐにそれを平らに考慮（ドン例えば、左外部結合をしないでください）。

var query = 
    (from m in dc.ChatPrivateMessageMasters 
    join d in dc.ChatPrivateMessageDetails on m.EmailID equals d.MasterEmailID 
    where (d.MasterEmailID == fromid && d.ChatToEmailID == toid) 
     || (d.MasterEmailID == toid && d.ChatToEmailID == fromid) 
    orderby d.ID descending 
    select new 
    { 
     m.UserName, 
     d.Message, 
     d.ID 
    }).Take(take).ToList(); 

をそして、それのVB.netと同等です：：

あなたのC＃のクエリは、単純にすることができ

Dim query = 
    (From m In dc.ChatPrivateMessageMasters 
    Join d In dc.ChatPrivateMessageDetails On m.EmailID Equals d.MasterEmailID 
    Where (d.MasterEmailID = fromid AndAlso d.ChatToEmailID = toid) 
    OrElse (d.MasterEmailID = toid AndAlso d.ChatToEmailID = fromid) 
    Order By d.ID Descending 
    Select m.UserName, d.Message, d.ID 
    Take take).ToList
