Xin chào các bạn, bài viết hôm nay mình chia sẻ đến các bạn, 8 đoạn code tạo hình ảnh từ Text có hiệu ứng trong lập trình C#, Winform.

[C#] Text Effect Winform

Trong bài này, mình sẽ sử dụng thư viện: TextdesignerCSLibrary

Các bạn có thể download ở source code của mình

Dưới đây là hình ảnh các hiệu ứng chữ C# winform: Trông cũng giống WordArt trong Microsoft Word. ^^
