如何LINQ方法語法轉換爲LINQ查詢語法

Question

如何轉換下面的LINQ方法語法LINQ查詢語法？有沒有一種工具可以幫助做到這一點？我知道LINQPAD可以從查詢語法轉換爲方法語法，但反之亦然。我想將其轉換爲查詢語法的原因是爲了做一些投影到一個模型，這樣我可以從所有的LINQ查詢中提到的表中選擇一些列。

var queryResult = CurrentContext.Set<AM_Response_T>().Include(t => t.AM_Master_T) 
     .Include(t => t.AM_Supporting_Evidences_T) 
     .Include("AM_Supporting_Evidences_T.Ticket_Repository_T") 
     .Include(t => t.AM_Response_Validation_T) 
     .Include("AM_Response_Validation_T.Amazon_Users_T") 
     .Include("AM_Response_Validation_T.Amazon_Users_T1") 
     .Include("AM_Response_Validation_T.AM_Validator_Type_T") 
     .Include(t => t.Catalog_Type_T) 
     .Include(t => t.Skills_T) 
     .Include("Skills_T.Record_Status_T") 
     .Include("Skills_T.BE_PS_Skill_Map_T") 
     .Include("Skills_T.BE_PS_Skill_Map_T.Skills_T1") 
     .Include("Skills_T.BE_PS_Skill_Map_T.Skills_T1.Record_Status_T") 
     .Include("Skills_T.BE_PS_Skill_Map_T.Skills_T1.BE_PS_Skill_Map_T") 
     .Include("Skills_T.BE_PS_Skill_Map_T.Skills_T1.KE_PS_Skill_Map_T") 
     .Include("Skills_T.KE_PS_Skill_Map_T") 
     .Include("Skills_T.KE_PS_Skill_Map_T.Skills_T1") 
     .Include("Skills_T.KE_PS_Skill_Map_T.Skills_T1.Record_Status_T") 
     .Include("Skills_T.KE_PS_Skill_Map_T.Skills_T1.BE_PS_Skill_Map_T") 
     .Include("Skills_T.KE_PS_Skill_Map_T.Skills_T1.KE_PS_Skill_Map_T") 
     .Include(t => t.Skill_Levels_T) 
     .Include(t => t.Skills_T.Skill_Levels_T) 
     .Include(t => t.Questions_T) 
     .Include(t => t.Questions_T.Question_Type_T) 
     .Include(t => t.AM_Master_T.AM_Master_Member_Map_T) 
     .Include(t => t.AM_Master_T.AM_Master_SPR_Map_T) 
     .Include(t => t.AM_Master_T.AM_Master_FSPR_Map_T) 
     .Include(t => t.AM_Master_T.AM_Master_FRP_Map_T) 
     .Include(t => t.AM_Master_T.AM_Master_Org_Function_Map_T) 
     .Include(t => t.AM_Master_T.AM_Master_RRP_Map_T) 
     .Include(t => t.AM_Master_T.AM_Master_Skills_Map_T) 
     .Include(t => t.AM_Master_T.AM_Master_FCM_Position_T) 
     .Include("AM_Master_T.AM_Master_FCM_Position_T.FCM_Position_T") 
     .Include(t => t.Amazon_Users_T) 
     .Include(t => t.Amazon_Users_T1) 
     .Include(t => t.AM_Response_Activity_T);

你並不需要使用此查詢語法，語法的方法將工作得很好。因爲我知道有沒有.INCLUDE的當量（）查詢語法

List<ModelYouWantToProjectTo> queryResult = CurrentContext.Set<AM_Response_T>() 
    .Include(t => t.AM_Master_T) 
    .Include(t => t.AM_Supporting_Evidences_T) 
    // Skipped a few 
    .Include(t => t.AM_Response_Activity_T) 
    .Select(t => new ModelYouWantToProjectTo 
     { 
      ModelProperty = t.Property, 
      // Etc... 
     }) 
    .ToList(); 

據：您可以在那裏和項目中使用。選擇（）和.ToList（）的模型。你可以混合使用這兩種語法，但是我發現它並不是很清楚。
