Question

我希望使用Java代码在我的网卡中设置dns ip地址，我正在寻找C＃ManagementClass和ManagementBaseObject中的一个例程来执行此操作。

using System;
using System.ComponentModel;
using System.Windows.Forms;
using System.Management;

//Modify IP Address, Subnet Mask, Default Gateway, DNS and ALternate DNS
public void setIP(string IPAddress, string SubnetMask, string Gateway, string DNS, string ALTDNS)
{
ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterCon
figuration");
ManagementObjectCollection objMOC = objMC.GetInstances();

foreach (ManagementObject objMO in objMOC)
{
ManagementBaseObject objNewIP = null;
ManagementBaseObject objSetIP = null;
ManagementBaseObject objNewGate = null;
ManagementBaseObject objNewDNS = null;
ManagementBaseObject objSetDNS = null;

if (!(bool)objMO["IPEnabled"])
continue;

try
{


objNewIP = objMO.GetMethodParameters("EnableStatic");
objNewGate = objMO.GetMethodParameters("SetGateways");
objNewDNS = objMO.GetMethodParameters("SetDNSServerSearchOrder");

//Set DefaultGateway
objNewGate["DefaultIPGateway"] = new string[] { Gateway };
objNewGate["GatewayCostMetric"] = new int[] { 1 };

//Set IPAddress and Subnet Mask
objNewIP["IPAddress"] = new string[] { IPAddress };
objNewIP["SubnetMask"] = new string[] { SubnetMask };

objSetIP = objMO.InvokeMethod("EnableStatic", objNewIP, null);
objSetIP = objMO.InvokeMethod("SetGateways", objNewGate, null);

objNewDNS["DNSServerSearchOrder"] = new string[] { DNS, ALTDNS };
objSetDNS = objMO.InvokeMethod("SetDNSServerSearchOrder", objNewDNS, null);

Console.WriteLine("Updated IPAddress, SubnetMask and Default Gateway!");
}
catch (Exception ex)
{
MessageBox.Show("Unable to Set IP : " + ex.Message);
}
finally
{
objNewIP = null;
objSetIP = null;
objNewGate = null;
objNewDNS = null;
objSetDNS = null;
}
}
}

那么，如何将此代码转换为Java？存在一些使用上面C＃代码中使用的ManagementClass和ManagementBaseObject的Java框架？

欢迎任何建议。

Java代码：

     Path path = Paths.get("c:\\dns.vbs");
     BufferedWriter writer = null;
