在C#中使用WMI

关于WMI的介绍可以参考https://www.cnblogs.com/zhaotianff/p/14764740.html

 

在C#中使用主要用到

ManagementClass和ManagementObjectSearcher两个类

 

示例代码如下：

 internal class WMIHelper
    {
        internal static string GetWmiProperty(string wmiObject,string propertyName)
        {
            ManagementClass managementClass = new ManagementClass(wmiObject);
            ManagementObjectCollection moc = managementClass.GetInstances();

            foreach (ManagementObject managementObject in moc)
            {
                return managementObject[propertyName].ToString();
            }
            return "";
        }

        internal static Dictionary<string,string> GetAllWmiProperty(string wmiObject)
        {
            Dictionary<string, string> dic = new Dictionary<string, string>();
            ManagementObjectSearcher managementObjectSearcher = new ManagementObjectSearcher("select * from " + wmiObject);

            foreach (ManagementObject managementObject in managementObjectSearcher.Get())
            {
                foreach (PropertyData property in managementObject.Properties)
                {
                    dic.Add(property.Name, property.Value == null ? "" : property.Value.ToString());
                }
            }

            return dic;
        }
    }

 

例如获取CPU ID

 internal static string GetCpuId()
        {
            return WMIHelper.GetWmiProperty("win32_processor", "processorid");
        }

 

获取CPU所有信息

WMIHelper.GetAllWmiProperty("win32_processor");
