C # read hard disk information ManagementClass class

One, in many cases, you may need to get the hardware information of the microcomputer. This sentence needs to be added as follows:

using System.Management;

To obtain hardware information, you need to know the hardware parameter information:

According to the information provided above, get what you need;

New ManagementClass ("win32_processor");  

The following describes the ManagementClass class;

1.GetInstances (): There are four overloads of this method;

2.Get (): There are two overloads for this method;

3.GetSubclasses (): There are four overloaded versions of this method

Two. Some applications of the ManagementClass class:

1. Get the CPU number

       /// <summary>        ///Get CPU Number/// </summary>        /// <returns></returns>         Public stringGetcpuid () {varCPUID =string.            Empty; varMC =NewManagementClass ("Win32_Processor"); varMOC =MC.            GetInstances (); foreach(varOinchMOC) {                varMo =(ManagementObject) o; CPUID= mo. properties["Processorid"].            Value.tostring (); }            returnCpuid; }

2. Get the hard drive serial number

Empty;9             varMC =NewManagementClass ("win32_diskdrive");Ten             varMOC =MC. GetInstances (); One             foreach(varOinchMOC) A             { -                 varMo =(ManagementObject) o; -HDid = (string) mo. properties["Model"]. Value; the                 //This statement solves the problem of having multiple physical disks, taking only the first physical hard disk -                  Break; -             } -             returnHDid; +}
