我已经看到很多代码允许我设置本地工作站的IP地址,但它只有在工作站已经有静态IP地址时才有效。我需要将适配器设置从自动获取IP地址更改为使用我提供的静态IP。
我现在使用的代码如下。它在每个objMO的第一个if语句中失败。我知道至少有一个适配器有IPv4加密(我可以在网络和共享中心看到它),但是,就像我说的那样,它设置为自动获取IP地址:
protected static void ChangeIPAndSubnet( IPAddress ipToSet, IPAddress subnetToSet )
{
ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection objMOC = objMC.GetInstances();
// change the IP for all active ManagementObjects
foreach (ManagementObject objMO in objMOC)
{
if ((bool)objMO["IPEnabled"])
{
try
{
ManagementBaseObject setIP;
ManagementBaseObject newIP = objMO.GetMethodParameters("EnableStatic");
// it's too bad that we have nice, neat ip addresses to use, only to change them
// back to strings, but that's how this code works
string ip_address = ipToSet.ToString();
string subnet_mask = subnetToSet.ToString();
newIP["IPAddress"] = new string[] { ip_address };
newIP["SubnetMask"] = new string[] { subnet_mask };
setIP = objMO.InvokeMethod("EnableStatic", newIP, null);
}
catch (Exception)
{
// report error
string strError = "The IP Address and/or Subnet mask could not be changed.\n";
strError += "Please check the values and try again";
MessageBox.Show(strError, "Settings Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
}
}
如何更改适配器设置以使用我提供的IP地址(和子网掩码)?
