-- 关于trycatch的问题
我做了个函数，用来测试是否能联通某个后台，如下所示：
Dim api As String = Args(0)
Dim url As String = "http://192.168.5.210:32177/" & api
Dim hp As New HttpClient(url)
hp.Timeout = 3
Dim s As String = ""
Try
s = hp.GetData()
Catch ex As Exception
s = ""
End Try
If s > "" Then
Return 1
Else
Return 0
End If
可是即使用了trycath但，还是跳出错误，rt所示：
