从同一个表合并2个查询到一个LINQ查询

Question

我有2个查询是查询同一个表，但使用不同的参数，我想结合成一体， 查询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 

查询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 

查询我想创建

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 

我还牛逼里德本

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)));
