How to change background color in C#?

Question

I' have form that user can select a color. I'm writing that color to my database for use other forms too.

When I'm saving a color to database it's looks like this;

Color [A=255, R=255, G=128, B=64]

How can i convert this and use as background color?

Answer 1

假设这是一个 WinForms 应用程序，使用Color.FromArgb() ：

BackColor = Color.FromArgb(a, r, g, b);

Answer 2

当您从数据库中读取时，您应该将Color.ToArgb()中的值存储在数据库中，并将Color.FromArgb()的值存储在数据库中。

Answer 3

int A = 255; int R=255; int G = 128; int B=64;
System.Drawing.Color c = System.Drawing.Color.FromArgb( A, R, G, B);

Answer 4

I you write the color to the dbase as a string then you can use the ColorConverter class, ConvertToString() and ConvertFromString() methods. Or you can store it as an integer, use the Color.ToArgb() and FromArgb() methods.
