Obtain the hardware information of the machine (cpu id serial number, motherboard information, hard disk serial number, and system information:
41 keywords: hardware CPU motherboard hard drive font: [large, medium, small]
In many cases, you may need to obtain the hardware information of the microcomputer. For example, you want to lock your software and prevent others from accessing it at will.
The most effective way is to get the serial number of the CPU, and then let your software run on a machine with such a serial number. As we all know, the CPU serial number is unique! Therefore, you can lock your software.
Another example that requires hard disk information is: the hard disk has several partitions, and each partition has its own space. When you are creating a multimedia application, you may also need to obtain hardware information about the sound card and video card.
Another wonderful application of this application is to obtain information about the system memory, such as the memory address and memory device.
Code usage
First, you must know that the function of this application is obtained by using the system. management class. Therefore, you need to add the following sentence:
using System.Management;
To obtain hardware information, you also need to create a managementobjectsearcher object.
ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from " + Key);
The key of the code above is a value that will be filled in with the correct data. For example, to obtain CPU information, you need to set the key value to win32_processor. The possible values of all keys are listed as follows:

First, call the get () method in the managementobjectsearcher instance (in this example, It is searcher). This method will fill in the returned information in this instance. Then, all you need to do is to process the data in the searcher instance.
foreach (ManagementObject share in searcher.Get())
{
// Some Codes ...
}
Each managementobject object contains some data that we need. Of course, we can process the data as follows:
foreach (PropertyData PC in share.Properties)
{
//some codes ...
}
The other part of the code in this article is just some operations on the listview control, which is very simple and will not be detailed again!
