Xin chào các bạn, bài viết hôm nay mình chia sẻ đến các bạn tools tạo class object từ table Sqlserver trong lập trình C#, Winform.

[C#] Create class object from table sqlserver

Trong lập trình ứng dụng, nếu bạn nào đang sử dụng Entity Framework để phát triển cho dự án của mình thì trong Entity đã có sẵn chức năng Migrate data to model object.

Tuy nhiên, nếu các nào đang sử dụng Dapper hoặc muốn tạo một class Object nhanh chóng từ Table Sqlserver, các bạn có thể downlaod tool bên dưới về để sử dụng.

Hoặc các bạn có thể tùy chỉnh lại theo nhu cầu sử dụng của mình.

Trong demo ứng phần mềm, mình có sử dụng công cụ CodeEditor để hiển thị code: Công cụ đó là ScintillaNET, các bạn có thể từ khóa này tìm trên github để tham khảo nhé.

Dưới đây là giao diện demo ứng:

Để sử dụng, các bạn nhập các thông tin kết nối database vào, xong chọn table cần tạo class để sử dụng.
