1. 第一步：加入參考
   專案→加入參考→.Net→System.Management
   第二步：引用命名空間
   using System.Management;
2. 第三步：調用WMI Class
   1：類別實體化
   例：
         ManagementClass mClass = new ManagementClass("Win32_Share");
   2：引用類別方法(Methods)
         例1：
         ManagementBaseObject mMethod = mClass.GetMethodParameters("Create");
   
         例2：
     

private void button24_Click(object sender, EventArgs e)
        {
            // Get the object on which the method will be invoked
            ManagementClass processClass =new ManagementClass("Win32_Process");

            // Get an input parameters object for this method
            ManagementBaseObject inParams = processClass.GetMethodParameters("Create");

            // Fill in input parameter values
            inParams["CommandLine"] = "calc.exe";

            // Method Options
            InvokeMethodOptions methodOptions = new InvokeMethodOptions(null,System.TimeSpan.MaxValue);

            // Execute the method
            ManagementBaseObject outParams =processClass.InvokeMethod("Create",inParams, methodOptions);

            // Display results
            // Note: The return code of the method is
            // provided in the "returnValue" property
            // of the outParams object
            MessageBox.Show("Creation of calculator process returned: " + outParams["returnValue"]);
            MessageBox.Show("Process ID: " + outParams["processId"]);
        } 



3：引用類別屬性(Properties)
      例1：利用foreach取得屬性
     

        private void button5_Click(object sender, EventArgs e)
        {//獲取CPU編號
            ManagementClass MyClass= new ManagementClass("Win32_Processor");
            ManagementObjectCollection MyCollection =  MyClass.GetInstances();
            String MyInfo="當前系統CPU編號為：";
            string MyCPUID = "";
            foreach (ManagementObject MyObject in MyCollection)
            {
               MyCPUID= MyObject.Properties["ProcessorId"].Value.ToString();
               break;
            }
            MyInfo += MyCPUID;
            MessageBox.Show(MyInfo, "訊息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
        }

      
      例2：


        private void button1_Click(object sender, EventArgs e)
        {
            ManagementClass mc = new ManagementClass("Win32_SerialPortConfiguration");
            ManagementObjectCollection moc = mc.GetInstances();

            foreach (ManagementObject mo in moc)
            {
                  // only return MAC Address from first card

                   MessageBox.Show (mo["Name"].ToString());
            }
         }
