CSharp 读取IP检测网络

1、引用库类

using System.Management;

 

2、关键代码

/* 获取网关 */
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
string gatw = "";
foreach (ManagementObject mo in moc)
{
    if (!(bool)mo["IPEnabled"])
        continue;
    string[] gateways = (string[])mo["DefaultIPGateway"];
    foreach (string gw in gateways)
        gatw += gw;
    //MessageBox.Show(gatw);
    break;
}
//return;



/* 检查网络是否正常 */

 // 引用系统库 using System.Net.NetworkInformation;

Ping p = new Ping();
PingReply pr = p.Send(gatw); //p.Send("192.168.1.1");
if (pr.Status != IPStatus.Success)
{
    MessageBox.Show("请检查网络");
    return;
}
