如果你想用Windows商店应用程序，后面跟着@Hans Kesting和@Jink回答:

    string colorcode = "#FFEEDDCC";
    int argb = Int32.Parse(colorcode.Replace("#", ""), NumberStyles.HexNumber);
    tData.DefaultData = Color.FromArgb((byte)((argb & -16777216) >> 0x18),
                          (byte)((argb & 0xff0000) >> 0x10),
                          (byte)((argb & 0xff00) >> 8),
                          (byte)(argb & 0xff));

假设你是指HTML类型的RGB代码(称为十六进制代码，如#FFCC66)，使用ColorTranslator类:

System.Drawing.Color col = System.Drawing.ColorTranslator.FromHtml("#FFCC66");

如果你使用的是ARGB十六进制代码，你可以使用System.Windows.Media命名空间中的ColorConverter类:

Color col = ColorConverter.ConvertFromString("#FFDFD991") as Color;
//or      = (Color) ColorConverter.ConvertFromString("#FFCC66") ;

我猜这是ARGB代码…你指的是system。drawing。color还是system。windows。media。color ?例如，后者在WPF中使用。我还没见过有人提到它，所以以防你在找它:

using System.Windows.Media;

Color color = (Color)ColorConverter.ConvertFromString("#FFDFD991");

    private Color FromHex(string hex)
    {
        if (hex.StartsWith("#"))
            hex = hex.Substring(1);

        if (hex.Length != 6) throw new Exception("Color not valid");

        return Color.FromArgb(
            int.Parse(hex.Substring(0, 2), System.Globalization.NumberStyles.HexNumber),
            int.Parse(hex.Substring(2, 2), System.Globalization.NumberStyles.HexNumber),
            int.Parse(hex.Substring(4, 2), System.Globalization.NumberStyles.HexNumber));
    }

XNA / Monogame (Microsoft.Xna.Framework.Color)。 适用于6或8(带alpha)字符的十六进制字符串 可能还有更好的替代方案(位屏蔽/移位)。

    using Microsoft.Xna.Framework;
    using System.Globalization;
    
    public static class ColorBuilder
    {
        public static Color FromHex(string color)
        {
            var hex = color.Replace("#", string.Empty);
            var h = NumberStyles.HexNumber;

            var r = int.Parse(hex.Substring(0, 2), h);
            var g = int.Parse(hex.Substring(2, 2), h);
            var b = int.Parse(hex.Substring(4, 2), h);
            var a = 255;

            if (hex.Length == 8)
            {
                a = int.Parse(hex.Substring(6, 2), h);
            }
 
            return new Color(r, g, b, a);
        }
    }
    
    //create a blue color
    var color = ColorBuilder.FromHex("#2733C5"); //or ColorBuilder.FromHex("2733C5");
    
    //create a blue color with 50% alpha
    var colorTrans = ColorBuilder.FromHex("#2733C580");
