First, WinForm computer blue screen effect

The first method: basic operations:

First step: Create a new C # form "Form1";

Step two: In the design window, change its properties:

1) Text property: Cancels the text in the Form1 Text property, and then lets the form name appear blank;

2) Showicon property: Because the WinForm form defaults to the icon, you only need to change the Showicon property to False (the icon is not displayed);

3) StartPosition property: Centerscreen;

4) Formboderstyle property: Set to none; (The border of the form will be removed)

5) BackColor property: Set to Hottrack, (you can also set other colors, here to show the realistic effect, using this color ...) )

The third step: you can add text and other control effects. Here are two pictures. (to show the realistic effect, xiaoqing or recommend the first one is better ...) ）

Effect One:

Effect Two:

The second way: to write code (but a bit of trouble oh ...) ）
