C # how to add a background image to a dynamically generated button in WINFORM
Below I provide several methods
First, use the Properties. Resources class. This method requires you to add images to the project in advance,
The method is as follows:

 

The code usage is as follows:

Button. BackgroundImage = namespace name. Properties. Resources. Image name; second, use the image method directly.
Using Bitmap. FromFile ("");
Let's take a look at the example below.

Button. BackgroundImage = Bitmap. FromFile ("d: \ 123.png"); the problem can be basically solved. Let's try again.

This is quite simple to determine, but recently several friends asked me on QQ, so I will send an article.

I believe there are other methods and better methods. I hope you can share your thoughts.
