如何篩選具有多個'和''或'條件的列表

Question

我想過濾以下SQL查詢格式的列表;

SQL

SELECT * FROM Tracker 
where (TrackProposalID = 6 and TrackRequestID = 0) or TrackRequestID = 16 

的LINQ

我曾嘗試，但迄今爲止收到語法錯誤;

listT = CType(listT.Where(Function(o) (o.TrackProposalID = 6 And o.TrackRequestID = 0) or (o.TrackRequestID = 16)).ToList 

Answer 1

在C＃

listT = listT.Where(o => (o.TrackProposalID == 6 && o.TrackRequestID == 0) || o.TrackRequestID == 16).ToList(); 

Answer 2

var newList = listT.Where(x=>(x.TrackProposalID == 6 && x.TrackRequestID == 0) || x.TrackRequestID == 16).ToList(); 

Answer 3

試試這個

listT = listT.Where(x=>(x.TrackProposalID == 6 && x.TrackRequestID == 0) || (x.TrackRequestID == 16).ToList(); 

Answer 4

var result = listT.Where(x => x.TrackRequestID == 16 || (x.TrackProposalID == 6 && x.TrackRequestID == 0)) 

，如果你不會讓ToList（）。它會執行每個呼叫「結果」。所以我推薦使ToList（）。
