增強此LINQ查詢的可讀性和性能？

Question

我不是LINQ的最大用戶，但我試圖檢索ModuleAvailabilities，其中academicYear是當前年份。

這裏有什麼改進嗎？

pathway.PathwayFoundationModule.Attach(
    pathway.PathwayFoundationModule.CreateSourceQuery() 
     .Include("Module") 
     .Include("Module.ModuleAvailabilities.Location") 
     .Where(o => o.Module.ModuleAvailabilities 
        .Where(x => x.AcademicYear == academicYear.Current) 
        .Count() >= 0) 
); 

Answer 1

我想你的意思

pathway.PathwayFoundationModule.Attach(
      pathway.PathwayFoundationModule.CreateSourceQuery() 
       .Include("Module") 
       .Include("Module.ModuleAvailabilities.Location") 
       .Where(o => o.Module.ModuleAvailabilities 
        .Any(x => x.AcademicYear == academicYear.Current));
