c# - C#：Picturebox使用的绘图方法

Question

背景：在 Picturebox 中，通过将 Bitmap 对象分配给 Picturebox 的 Image 属性，可以在屏幕上绘制位图图像。

问题： Picturebox在屏幕上绘制位图图像的绘制方法（GDI+？）是什么？

提前致谢。

Answer 1

If by PictureBox you mean System.Windows.Forms.PictureBox, it paints with GDI+ as GDI+ is the rendering technology used by all of Windows Forms (WinForms). The GDI+ "wrapper" for WinForms comes from System.Drawing.

Windows Presentation Foundation (WPF) on the other hand, uses DirectX to "paint". WPF does not have a PictureBox control.
