类的错误控制问题

[epjack]

Public Class Class1
Private errdes
Public ReadOnly Property errDescription()
Get
Return errdes
End Get
End Property

Public Function geturl(ByVal url As String)
Try
'.....
Catch ex As Exception
'....
End Try

End Function
End Class

请教，如何将geturl()中的发生的错误信息返回给类的属性errdescription，请终止geturl的执行。

在错误处理模块里 直接写你要想要的代码 .

谢谢，geturl不返回值，vb.net 2005 会提示有问题的．

[vinsonhwj]

Public Function geturl(ByVal url As String)
Try
return "Vinson" ' 填你想返回的结果。
Catch ex As Exception
errdes = ex.message
return nothing ‘在调用geturl的地放要判断geturl是否为Nothing
End Try

End Function
