方法一：调用cmd 的ping命令
private static string CmdPing(string strIp)
{
Process p = new Process(); p.StartInfo.FileName = "cmd.exe";//设定程序名
p.StartInfo.UseShellExecute = false; //关闭Shell的使用
p.StartInfo.RedirectStandardInput = true;//重定向标准输入
p.StartInfo.RedirectStandardOutput = true;//重定向标准输出
p.StartInfo.RedirectStandardError = true;//重定向错误输出
p.StartInfo.CreateNoWindow = true;//设置不显示窗口
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 = "连接";
}
else if (strRst.IndexOf("Destination host unreachable.") != -1)
{
pingrst = "无法到达目的主机";
}
else if (strRst.IndexOf("Request timed out.") != -1)
{
pingrst = "超时";
}
else if (strRst.IndexOf("Unknown host") != -1)
{
pingrst = "无法解析主机";
}
else
{
pingrst = strRst;
}
p.Close();
return pingrst;
}
方法二：使用C#中的ping 类
private void displayReply(PingReply reply) //显示结果
{
Ping p1 = new Ping(); //只是演示，没有做错误处理
PingReply reply = p1.Send("填写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("超时");
}else{
response.write("失败");
}
}
