网络状况确认工具 主要包括：HostTransforIP、PingHost、PingPort、PingServer
1 HostTransforIP
private IPAddress HostTransforIP(string host

ipString
= new IPEndPoint(Dns
.GetHostEntry(host
).AddressList
[0], 0).Address
.ToString();
}

)
{
this.showMsg("DNS Exception:" + (object) ex
);
throw new Exception("DNS Exception:" + (object) ex
);
}

.Parse(ipString
);
}
2 PingHost
private void PingHost(string host
)
{
try
{

= new Process();
process

.Arguments
= host
;
process
.StartInfo
.UseShellExecute
= false;
process
.StartInfo
.CreateNoWindow
= true;
process
.StartInfo
.FileName
= "ping.exe";
process
.StartInfo
.RedirectStandardInput
= true;
process
.StartInfo
.RedirectStandardOutput
= true;
process
.StartInfo

= true;
process
.Start();
string end
= process

.ReadToEnd();
process
.Close();
}
catch (Exception ex
)

}
}
3 PingPort
private void PingPort(string host
, int port
)
{
try

Stopwatch stopwatch
= new Stopwatch();
stopwatch
.Start();

= new Socket(AddressFamily
.InterNetwork
, SocketType
.Stream
, ProtocolType
.Tcp
))

) ipEndPoint
);
stopwatch
.Stop();
}
}
catch (Exception ex
)

}
}
4 PingServer
private void PingServer(string uri

stopwatch
.Start();
XMLHTTP instance

, (object) false, (object) null, (object) null);
instance
.send((object) bstrUrl
);
int status
= instance
.status
;
stopwatch
.Stop();
if (status
== 200)
{
this.showMsg("PingServer 終了（" + stopwatch
.ElapsedMilliseconds
.ToString() + "ms）");
}
else
{

.ToString());
}
}
catch (Exception ex
