如何通过 C# 代码生成图像？

Question

I've got a button in my WinForms plugin. It's got an image on it. The thing is, when I click the button, I want the image to change from whatever image it is now, to whatever image I want it to be.

So basically how do i make button change its image? The image type is System.Drawing.Image .

Answer 1

In order to change a Button 's image in WinForms you set it's Image property. You can either load a bitmap from a file with Bitmap.FromFile , or you can draw an image using the Graphic class by creating a new instance of Bitmap using the Width/Height constructor (ie new Bitmap(100, 100) ) and then use the Graphic.FromImage method. Lookup the documentation on the Graphic class for more info.
