C#中的ManagementClass类

C# 提供了ManagementClass类来获取本机的一些基本信息，比如CPU的个数，CPU的频率，网卡的MAC，内存的大小，硬盘的大小等。

获取本机MAC地址：

       /// <summary>
       /// 获取本机的MAC地址
       /// </summary>
       /// <returns></returns>
       public static string GetMACString()
       {
           ManagementClass mAdapter = new ManagementClass("Win32_NetworkAdapterConfiguration");
           ManagementObjectCollection mo = mAdapter.GetInstances();
           foreach (ManagementBaseObject m in mo)
           {
               if ((bool)m["IpEnabled"] == true)
               {
                   return m["MacAddress"].ToString();
               }
           }
           mo.Dispose();
           return null;
       }

获取本机CPU的个数：

/// <summary>
       /// 获取CPU的个数
       /// </summary>
       /// <returns></returns>
       public static int GetCpuCount()
       {
           try
           {
               using (ManagementClass mCpu = new ManagementClass("Win32_Processor"))
               {
                   ManagementObjectCollection cpus = mCpu.GetInstances();
                   return cpus.Count;
               }
           }
           catch
           {
           }
           return -1;
       }

获取本机CPU的频率

/// <summary>
       /// 获取CPU的频率 这里之所以使用string类型的数组，主要是因为cpu的多核
       /// </summary>
       /// <returns></returns>
       public static string[] GetCpuMHZ()
       {
           ManagementClass mc = new ManagementClass("Win32_Processor");
           ManagementObjectCollection cpus = mc.GetInstances();

           string[] mHz = new string[cpus.Count];
           int c = 0;
           ManagementObjectSearcher mySearch = new ManagementObjectSearcher("select * from Win32_Processor");
           foreach (ManagementObject mo in mySearch.Get())
           {
               mHz[c] = mo.Properties["CurrentClockSpeed"].Value.ToString();
               c++;
           }
           mc.Dispose();
           mySearch.Dispose();
           return mHz;
       }

获取本机硬盘的大小

/// <summary>
       /// 获取硬盘的大小
       /// </summary>
       /// <returns></returns>
       public static string GetSizeOfDisk()
       {
           ManagementClass mc = new ManagementClass("Win32_DiskDrive");
           ManagementObjectCollection moj = mc.GetInstances();
           foreach (ManagementObject m in moj)
           {
               return m.Properties["Size"].Value.ToString();
           }
           return "-1";
       }
    

获取本机内存的大小：

/// <summary>
       /// 获取内存的大小
       /// </summary>
       /// <returns></returns>
       public static string GetSizeOfMemery()
       {
           ManagementClass mc = new ManagementClass("Win32_OperatingSystem");
           ManagementObjectCollection moc = mc.GetInstances();

           double sizeAll = 0.0;
           foreach (ManagementObject m in moc)
           {
               if (m.Properties["TotalVisibleMemorySize"].Value != null)
               {
                   sizeAll += Convert.ToDouble(m.Properties["TotalVisibleMemorySize"].Value.ToString());
               }
           }
           mc = null;
           moc.Dispose();

           return sizeAll.ToString();
       }

本程序是使用VS2005编写的，可运行。

ManageMentClass 对象被实例化时，根据初始化参数的不同能够获取不同的本地信息："Win32_NetworkAdapterConfiguration" 获取本机网络适配器对象。据此可以获取网络地址等。"Win32_DiskDiver" 获取本机硬盘的相关信息，"Win32_Processor" 获取本机CPU相关的信息。"Win32_OperatingSystem" 获取内存等相关信息。
