從同一個表合併2個查詢到一個LINQ查詢

Question

我有2個查詢是查詢同一個表，但使用不同的參數，我想結合成一體， 查詢1

//ToDo refactor 
     int myDayOfWeek = 0; 
     DateTime dt = DateTime.Today; 
     myDayOfWeek = (int)dt.DayOfWeek; 

     var todaysLecture = (from c in _context.LectureGigs.Where(g => g.IsWeekLy == true && (int)g.Days == (myDayOfWeek)) 
          select c).ToList(); 
     //results Ok 1 result 

查詢2

var upCommingLecture = _context.LectureGigs 
      .Include(g => g.Artist).Include(g => g.Genre) 
      .Where(g => g.DateTime > DateTime.Now && !g.IsCanceled); 
     //results Ok 2 result 

查詢我想創建

var upCommingLecture = _context.LectureGigs 
      .Include(g => g.Artist).Include(g => g.Genre).Where(g => g.IsWeekLy == true && (int)g.Days == (myDayOfWeek)) 
      .Where(g => g.DateTime > DateTime.Now && !g.IsCanceled); 
     //Error none but 0 result 

我還牛逼裏德本

var upCommingLecture = _context.LectureGigs 
      .Include(g => g.Artist).Include(g => g.Genre) 
      .Where(g => g.DateTime > DateTime.Now && !g.IsCanceled && g.IsWeekLy==true &&(int)g.Days==(myDayOfWeek)); 
     //Error none but 0 result 

Answer 1

OR（||），不和（&&）

var upCommingLecture = _context.LectureGigs 
     .Include(g => g.Artist).Include(g => g.Genre) 
     .Where(g => (g.DateTime > DateTime.Now && !g.IsCanceled) 
       || (g.IsWeekLy==true &&(int)g.Days==(myDayOfWeek)));
