篩選出Linq查詢

Question

我有列表列表courseTakenList.i想過濾掉Completed,Dropped,Current,Schudeled 。 這是代碼示例。

courseTakenList = (from courseTaken in courseTakenList
                      select new Course
                      {
                           Status = "Scheduled"?"COMPLETE"?"Dropped"? "Current"
                      }).ToList();

Answer 1

您可以做得更簡潔

var statuslist= {"Completed","Dropped","Current","Schudeled"};

var courses = courseTakenList.Where(courseTaken => 
                       statuslist.Contains(courseTaken.Status);

Answer 2

Linq In查詢將解決您的問題

var statuslist= {"Completed","Dropped","Current","Schudeled"};

var query = from courseTaken in courseTakenList
            where statuslist.Contains( courseTaken .Status )
            select courseTaken ;

注意 ：根據需要更改select子句
