现在学生机已经连接到我服务端了，我现在想要发送命令过去，设置学生机IP，让他们不能上网哈哈，命令用socket发送就可以了，这个在前面几个文章中已经讲过了，现在来看看怎么更改IP这个些东西。

代码如下：

/// <summary>
/// 设置IP MASK DNS
/// </summary>
/// <param name="ip"></param>
/// <param name="submask"></param>
/// <param name="getway"></param>
/// <param name="dns"></param>
public void SetNet(string[] ip, string[] submask, string[] getway, string[] dns)
{
    ManagementClass wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");
    ManagementObjectCollection moc = wmi.GetInstances();
    ManagementBaseObject inPar = null;
    ManagementBaseObject outPar = null;
    foreach (ManagementObject mo in moc)
    {
        //如果没有启用IP设置的网络设备则跳过
        if (!(bool)mo["IPEnabled"])
            continue;

        //设置IP地址和掩码
        if (ip != null && submask != null)
        {
            inPar = mo.GetMethodParameters("EnableStatic");
            inPar["IPAddress"] = ip;
            inPar["SubnetMask"] = submask;
            outPar = mo.InvokeMethod("EnableStatic", inPar, null);
        }

        //设置网关地址
        if (getway != null)
        {
            inPar = mo.GetMethodParameters("SetGateways");
            inPar["DefaultIPGateway"] = getway;
            outPar = mo.InvokeMethod("SetGateways", inPar, null);
        }

        //设置DNS地址
        if (dns != null)
        {
            inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");
            inPar["DNSServerSearchOrder"] = dns;
            outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);
        }
    }
}

用法示例

--------------说明------------------</para>

string[] ip = { "192.168.1.2" };

string[] ipmask = { "255.255.255.0" };

string[] gateway = { "192.168.1.1" };

string[] dns = { "114.114.114.114","227.210.210.210" };

SetNet(ip, ipmask, gateway, dns);
