如何取得ping返回值

[zydyw]

ASP.NET中怎样取得dos命令ping的返回值或者有好的办法确认网络的通讯正常。

public virtual bool Connected
{
get
{
try
{
//检查socket的状态是否可读
if(m_socket.Connected && m_socket.Poll(0, SelectMode.SelectRead))
{
byte[] aByte = new byte[1];
//因为TCP/IP协议无法精确的判断网络是否可用
//试读一个字符，Peek参数指定读取的字符不会从缓冲区中移除
//假如可读则表示连接可用
if(m_socket.Receive(aByte, 0, 1, SocketFlags.Peek) != 0)
return true;
Close("Disconnected.");
return false;
}
}
catch(SocketException e)
{
OnException(e);
}
return m_socket.Connected;
}
}

While (Not proc.HasExited)
proc.WaitForExit(500)
End While
Dim pingResult As String = proc.StandardOutput.ReadToEnd()
If pingResult <> "" Then
End If
proc.StandardOutput.Close()
Catch ex As Exception
Finally
Try
proc.Close()
proc.Dispose()
Catch ex As Exception
End Try
End Try

pingResult即返回结果

If pingResult <> "" Then
中可以填入你的处理
