自定义颜色转换

前端

<Grid Background="#ffffff" x:Name="brdStateBackground" />

后台

using System.Windows.Media;

brdStateBackground.Background = new SolidColorBrush((Color)ColorConverter.ConvertFromString("#ffffff"));

//string转Color
(Color)ColorConverter.ConvertFromString((string)str);

"#FFFFFF"转Color

public Color StringToColor(string colorName)
{
    if (colorName.StartsWith("#"))
    {
        colorName = colorName.Replace("#", string.Empty);
    }
    if (int.TryParse(colorName, System.Globalization.NumberStyles.HexNumber, null, out int value))
    {
        return Color.FromArgb(
            //Convert.ToByte((value >> 24) & 255),  // a 默认为255，即不透明
            Convert.ToByte((value >> 16) & 255),  // R
            Convert.ToByte((value >> 8) & 255),   // G
            Convert.ToByte((value >> 0) & 255)    // B
            );

    }
    return Color.Red;
}
