SQL查询到左LINQ的加入到实体

我有以下SQL查询SQL查询到左LINQ的加入到实体

Select LC.*,LP.[LandingPageName] from [LandingPageCompanies] LC 
Left join [LandingPageContent] LP on LP.SubCategoryID=LC.SubCategoryID 
where LC.[CategoryID]=17

，我需要将其转换为LINQ to entity。

我试过下面的查询，但它的工作作为Inner join

var data = (from t1 in dbSavingContainer.LandingPageCompanies 
         join t2 in dbSavingContainer.LandingPageContents on t1.SubCategoryID equals t2.SubCategoryID 
         where t1.CategoryID == CategoryID 
         select new 
         { 
          CategoryID = t1.CategoryID, 
          CompanyID = t1.CompanyID, 
          CompanyLink = t1.CompanyLink, 
          CompanyLogo = t1.CompanyLogo, 
          CompanyName = t1.CompanyName, 
          SubCategoryID = t1.SubCategoryID, 
          LandingPageName = t2.LandingPageName 
         }).ToList();

如果缺乏即时。？

答案实际上应该是一个评论，更超过代替发布一个链接，你应该写查询，因为该链接可能会在未来被删除，并使这个答案obselete – praveen 2013-03-22 11:37:40

我是新来这个网站，我认为低声誉我无法评论，这就是为什么我必须发布答案。顺便说一句，现在考虑评论，一旦得到privelege这样做。 – 2013-03-22 11:43:11
