最佳回答

我现在想知道,我如何能够在我的过滤方法中增加额外的参数。

你可以这样做,手递签名必须与活动签名相符。 最容易的解决办法是把这个年龄储存在外地,并在你的手里利用这个领域:

Private _age As Int32

Public Sub FilterByAge(ByVal Item As Object, ByVal e As FilterEventArgs)
     
     
    Dim PersonToFilter As Person = TryCast(e.Item, Person)
     
     
    If Not PersonToFilter.Age = _age Then
         
        e.Accepted = False
         
    End If
     
     
End Sub
