Xin chào các bạn, bài viết hôm nay mình xin chia sẽ đến các bạn source code C# lấy thông tin chi tiết của phần cứng (Hardware) của máy tính của mình, code phần mềm được chia sẽ bởi tác giả Alireza shirazi.

[C#] Share source code lấy thông tin hardware (phần cứng máy tính)

Trong lập trình C#, các bạn muốn lấy các thông tin của các phần cứng máy tính như: CPU, RAM, HDD, SSD, Network, BIOS, Sound Card, Video Card, USB...

Thì trong C#, Microsoft đã cung cấp cho chúng ta thư viện qua class System.Management.

Các bạn phải import thư viện này vào project của mình nhé.

Trong thư viện này, nó cung cấp cho chúng ta một class object ManagementObjectSearcher.

Để lấy các thông tin cụ thể của từng phần cứng chúng ta sẽ sử dụng câu truy vấn query theo cú pháp như bên dưới đây, và chúng ta sẽ hiển thị thông tin đó ra ListView, hoặc sử dụng theo mục đích của mình.

Câu truy vấn của ManagementObjectSearcher C#:

ManagementObjectSearcher searcher = new ManagementObjectSearcher(
    "select * from " + Key);

Ở đây, chúng ta cần truyền vào tham số của Key để trả về thông tin của phần cứng đó.

Giao diện demo ứng dụng lấy thông tin Hardware C#:

và
