Question

如果我这样做，我有一个正确的linq语句

Dim mList = From w In oS
            Where w.Active = True
            Select w

Dim mlist2 = From w In mList
             Where w.EmployeeID <> 19
             Select w

Dim mlist3 = From w In mlist2
             Where w.EmployeeID <> 20
             Select w

我想将它们合并为一个陈述但却无法解决问题。这不起作用，它会过滤掉w.Active = true，但19和20的EmployeeID不会被过滤掉。

Dim mList = From w In oS
            Where w.Active = True AndAlso (w.EmployeeID <> 19 Or w.EmployeeID <> 20)
            Select w

Answer 1

您需要为每个语句添加位置原因。

Dim mList =来自w In OS 其中w.Active = True AndAlso（w.EmployeeID <> 19或w.EmployeeID <> 20）选择w

让linq在where子句中使用多个条件
