C # To obtain information about the local computer

Create a class. And then read the information. The calling code is as follows.
Hardinfoclass myclass=new Hardinfoclass ();
Textbox1.text=myclass. Getharddiskid ();
Textbox2.text=myclass. Getcpuid ();
Textbox3.text=myclass. Getnetcardmac ();
Textbox4.text=myclass. Getnetcardip ();
Textbox5.text=myclass. GetHostName ();
Textbox6.text=myclass. Getvolof ("D");//c plate 58c6b679 is different from D disk 6ed62864

Textbox7.text=myclass. GetHashCode ();
Textbox8.text=myclass. Getcpuid ();

The class Hardinfoclass code is as follows

Using System;
Using System.Net;
Using System.Runtime.InteropServices;
Using System.Management; Need to refer to the System.Management.DLL file in the solution
