如何在不将LINQ语句分配给变量的情况下执行它？
|
我有以下功能
Public Function GetPositionBySchoolID(ByVal SchoolID As Integer) As CPAPositionsDataTable
Dim positions As New CPAPositionsDataTable
Dim tmp = (From pos In PositionsAdapter.GetData()
Where (pos.SchoolID = SchoolID)
Select pos)
tmp.ToList.ForEach(Sub(i) positions.ImportRow(i))
Return positions
End Function
Public Function GetPositionBySchoolID(ByVal SchoolID As Integer) As CPAPositionsDataTable
Dim positions As New CPAPositionsDataTable
(From pos In PositionsAdapter.GetData()
Where (pos.SchoolID = SchoolID)
Select pos).ToList.ForEach(Sub(i) positions.ImportRow(i))
Return positions
End Function
没有找到相关结果

PositionsAdapter.GetData().Where(Function(pos) pos.SchoolID = SchoolID) _ .ToList().ForEach(Sub(i) positions.ImportRow(i))搂腹时
，因此可以迭代。 另外，您可以创建一个方法（由于LINQ堆栈是关于没有副作用，而都是关于副作用），因此未包含在内）作为的扩展，您不必在调用之前。
