Use

System.Drawing.Color.FromArgb(myHashCode);

    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));
    }

我需要将HEX颜色代码转换为System.Drawing。颜色，特别是在WPF表单上作为背景的爱丽丝蓝的阴影，并发现找到答案的时间比预期的要长:

using System.Windows.Media;

--

System.Drawing.Color myColor = System.Drawing.ColorTranslator.FromHtml("#EFF3F7");
this.Background = new SolidColorBrush(System.Windows.Media.Color.FromArgb(myColor.A, myColor.R, myColor.G, myColor.B));

Use

System.Drawing.Color.FromArgb(myHashCode);

你可以看到Silverlight/WPF用十六进制的颜色设置椭圆来使用十六进制值:

your_contorl.Color = DirectCast(ColorConverter.ConvertFromString("#D8E0A627"), Color)

对于任何Xamarin开发人员，您都需要了解

指定颜色类型，以防止强制转换异常假设您谈论的是Xamarin.Forms.Color 创建一个ColorConverter类型的对象

var conv = new System.Drawing.ColorConverter();
var color = (System.Drawing.Color)conv.ConvertFromString("#FF1D65AE");
