Asp.net 验证失败，重定向到其他网页

当验证失败超过3次时，用户将转到另一个页面，我如何编码？

我将使用CustomValidator执行验证。在CustomValidator的代码中，我将使用ViewState变量跟踪验证失败的次数，如果变量>3，则我将使用Response.Redirect（）转到其他页面

下面是一些示例代码：

     Property ValidationFailed() As Integer
        Get
            If ViewState("ValidationFailed") Is Nothing Then
                Return 0
            Else
                Return ViewState("ValidationFailed")
            End If
        End Get
        Set(ByVal value As Integer)
            ViewState("ValidationFailed") = value
        End Set
    End Property

    Public Function ValidationCode(ByVal arg As Object) As Boolean
        'TODO: Code that does the validation
    End Function

    Protected Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
        args.IsValid = ValidationCode(args.Value)
        If Not args.IsValid Then
            ValidationFailed = ValidationFailed + 1
        End If
        If ValidationFailed > 3 Then
            Response.Redirect("somepage.aspx")
        End If
    End Sub
