Set System.Drawing.Color values

Question

Hi how to set R G B values in System.Drawing.Color.G ?

which is like System.Drawing.Color.G=255; is not allowed because its read only

Property or indexer 'System.Drawing.Color.G' cannot be assigned toit is read only 

i just need to create a Color Object by assigning custom R G B values

Answer 1

You could create a color using the static FromArgb method:

Color redColor = Color.FromArgb(255, 0, 0); 

You can also specify the alpha using the following overload.

Answer 2

The Color structure is immutable (as all structures should really be), meaning that the values of its properties cannot be changed once that particular instance has been created.

Instead, you need to create a new instance of the structure with the property values that you want. Since you want to create a color using its component RGB values, you need to use the FromArgb method:

Color myColor = Color.FromArgb(100, 150, 75);
