vb.net - linq2sql的交叉连接问题

Question

我有以下 LINQ2SQL 查询:

From pc In DBContext.ProcessCodes
Join c In DBContext.Cells On pc.idCell Equals c.idCell
    Where pc.idType = "Cars" AndAlso
          pc.Active = True AndAlso
          c.Active = True
    Select c

出于某种原因，当我认为我应该获得内部连接时，我却获得了交叉连接(笛卡尔积)。如果我在 where 中进行多个 From 的键比较，我会得到同样的结果。

我做错了什么？

Answer 1

我认为这对你有帮助:

From pc In DBContext.ProcessCodes 
From c In DBContext.Cells
Where pc.idType = "Cars" AndAlso           
      pc.Active = True AndAlso
      c.Active = True     
Select c
