How to resize canvas through code?

Question

Unity

Hello ! During the test of the game, I noticed that the screen resolution does not match with some devices, how can I change the screen size with a code?

Answer 1

The code is not necessary, in the canvas there is a section "Render mode", and there select "Screen space - camera". Next, put "Main Camera" a little lower in "Render camera". Now the canvas will always be under the camera size.
