方法一:調用cmd 的ping命令
private static string CmdPing(string strIp)
{
Process p = new Process(); p.StartInfo.FileName = "cmd.exe";//設定程式名
p.StartInfo.UseShellExecute = false; //關閉Shell的使用
p.StartInfo.RedirectStandardInput = true;//重新導向標準輸入
p.StartInfo.RedirectStandardOutput = true;//重新導向標準輸出
p.StartInfo.RedirectStandardError = true;//重新導向錯誤輸出
p.StartInfo.CreateNoWindow = true;//設定不顯示視窗
string pingrst; p.Start(); p.StandardInput.WriteLine("ping " + strIp);
p.StandardInput.WriteLine("exit");
string strRst = p.StandardOutput.ReadToEnd();
if (strRst.IndexOf("(0% loss)") != -1)
{
pingrst = "串連";
}
else if (strRst.IndexOf("Destination host unreachable.") != -1)
{
pingrst = "無法到達目的主機";
}
else if (strRst.IndexOf("Request timed out.") != -1)
{
pingrst = "逾時";
}
else if (strRst.IndexOf("Unknown host") != -1)
{
pingrst = "無法解析主機";
}
else
{
pingrst = strRst;
}
p.Close();
return pingrst;
}
方法二:使用C#中的ping 類
private void displayReply(PingReply reply) //顯示結果
{
Ping p1 = new Ping(); //只是示範,沒有做錯誤處理
PingReply reply = p1.Send("填寫ip地址");
StringBuilder sbuilder ;
if (reply.Status == IPStatus.Success)
{
sbuilder = new StringBuilder();
sbuilder.Append(string.Format("Address: {0} ", reply.Address.ToString ()));
sbuilder.Append(string.Format("RoundTrip time: {0} ", reply.RoundtripTime));
sbuilder.Append(string.Format("Time to live: {0} ", reply.Options.Ttl));
sbuilder.Append(string.Format("Don‘t fragment: {0} ", reply.Options.DontFragment));
sbuilder.Append(string.Format("Buffer size: {0} ", reply.Buffer.Length));
response.write(sbuilder.ToString());
}
else if (reply.Status == IPStatus.TimeOut)
{
response.write("逾時");
}else{
response.write("失敗");
}
}
