Ping超时时间

我有一个完全正常工作的ping代码,但我发现,如果ping返回时间很长,它将被标记为脱机。

代码:

 Try
        If BackgroundWorker1.CancellationPending Then
            Exit Sub
        End If
        If My.Computer.Network.Ping(PRIBox.Text) Then
            'Online
            If GetPingMs(PRIBox.Text) < 125 Then
                'Good ping
                PRIPingIcon.Image = My.Resources.PingUP
            Else
                'Bad ping
                PRIPingIcon.Image = My.Resources.PingHIGH
            End If
        Else
            PRIPingIcon.Image = My.Resources.PingDOWN
            'Offline
        End If
    Catch
    End Try

在使用此功能的情况下,有没有超时,等于1500毫秒,或类似的东西?

我用于长往返

的附加功能
Public Function GetPingMs(ByVal address As String) As Long
    Dim ping As New System.Net.NetworkInformation.Ping
    Return ping.Send(address).RoundtripTime
End Function

想出来,抱歉浪费你所有的时间!

 Try
    If BackgroundWorker1.CancellationPending Then
        Exit Sub
    End If
    If My.Computer.Network.Ping(PRIBox.Text, 1500) Then '<----
        'Online
        If GetPingMs(PRIBox.Text) < 125 Then
            'Good ping
            PRIPingIcon.Image = My.Resources.PingUP
        Else
            'Bad ping
            PRIPingIcon.Image = My.Resources.PingHIGH
        End If
    Else
        PRIPingIcon.Image = My.Resources.PingDOWN
        'Offline
    End If
Catch
End Try
