How to create a System.Drawing.Color from its hexadecimal RGB string?
I want to create a System.Drawing.Color
from a value like #FF00FF
or FF00FF
without needing to write code for that. T开发者_运维问答here is any .NET built-in parser for that?
ColorTranslator.FromHtml("#FF00FF");
You can use the System.Drawing.ColorTranslator static method FromHtml.
use:
System.Drawing.ColorTranslator.FromHtml("#FFFFFF");
It is rather easy when you use the Convert-Class. The ToInt32
function has an overload with a second parameter which represents the base the string is in.
using System.Drawing
Color yourColor = Color.FromARGB(Convert.ToInt32("FF00FF", 16));
Use the ColorConverter class:
var converter = System.ComponentModel.TypeDescriptor.GetConverter( typeof( Color ) );
color = converter.ConvertFromString( "#FF00FF" );
This can also convert from the standard named colors e.g. ConvertFromString( "Blue" )
See here for a discussion of the standard .NET type conversion mechanisms.
If the color you want to use is a constant, in C# use System.Drawing.Color.FromArgb (0xFF00FF)
. That is slightly faster than System.Drawing.Color.FromName
or System.Drawing.Color.FromHtml
, since the parsing from a string to integer is done at compile time rather than at runtime.
The FromName method worked for me
System.Drawing.Color.FromName("#FF00FF");
