C# Management 類獲取本機各種信息

1. 添加

System.Management 的引用

2. 在cs代碼中初始化引用

ManagementClass mc = new ManagementClass("引用的WMI庫名稱");

可供引用的WMI類庫在MSDN中可查到：

http://msdn.microsoft.com/en-us/library/aa394084(v=VS.85).aspx

3. 獲取WMI實例

ManagementObjectCollection moc= vNetworkAdapter.GetInstances();

這裏獲取到的是WMI實例集合，例如，獲取網絡適配器信息，這裏會獲取到無線連接、有線連接、1394連接等與網絡連接有關的實例集合。

4. 循環個實例獲取其屬性

foreach (ManagementObject mo in moc)
{

　　//TODO: 獲取各實例屬性

　　//實例各屬性、方法、解釋也可在http://msdn.microsoft.com/en-us/library/aa394084(v=VS.85).aspx裏查到

}

5. 修改

修改需要用到 ManagementObject.InvokeMethod(MethodName, ManagementBaseObject, InvokeMethodOptions ); 方法

MethodName 爲要執行的方法名稱的，也可在上面MSDN的鏈接中查到；

ManagementBaseObject 不好解釋，官方解釋爲“包含管理對象的基本元素。用作管理更具體的管理對象類的基類。”

InvokeMethodOptions 執行附加選項，可以爲NULL。

 

完整實例：

ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject  mo in moc)
{
    //如果沒有啓用IP設置的網絡設備則跳過   
    if (!(bool)mo["IPEnabled"])
        continue; 

    // 獲取屬性
    string caption = mo["Caption"].ToString();              //名稱
    string[] addresses = (string[])mo["IPAddress"];         //IP地址
    string[] subnets = (string[])mo["IPSubnet"];            //子網掩碼
    string[] gateways = (string[])mo["DefaultIPGateway"];   //網關
    string[] dnses = (string[])mo["DNSServerSearchOrder"];  //DNS

    ManagementBaseObject newIP;

    // 修改IP及子網掩碼
    newIP = mo.GetMethodParameters("EnableStatic");    
    newIP["IPAddress"] = new string[] { "192.168.2.51" };
    newIP["SubnetMask"] = new string[] { "255.255.255.0" }; //修改IP同時，需要填寫子網掩碼
    mo.InvokeMethod("EnableStatic", newIP, null);
    

    // 設置網關地址 
    newIP = mo.GetMethodParameters("SetGateways");
    newIP["DefaultIPGateway"] = new string[] { "192.168.2.1" };
    mo.InvokeMethod("SetGateways", newIP, null);

    // 設置DNS 
    newIP = mo.GetMethodParameters("SetDNSServerSearchOrder");
    newIP["DNSServerSearchOrder"] = new string[] { "192.168.1.10" };
    mo.InvokeMethod("SetDNSServerSearchOrder", newIP, null);
