How do I convert a Color to a Brush in C#?
Color
Brush
这是从 Color到 Brush。
你不能转换它,你必须做一个新的刷子... 。
SolidColorBrush brush = new SolidColorBrush( myColor );
现在,如果您在 XAML 中需要它,您可以制作一个自定义值转换器并在绑定中使用它
Brush brush = new SolidColorBrush(color);
反过来说:
if (brush is SolidColorBrush colorBrush) Color color = colorBrush.Color;
或者类似的东西。
Point being not all brushes are colors but you could turn all colors into a (SolidColor)Brush.
SolidColorBrush brush = new SolidColorBrush( Color.FromArgb(255,255,139,0) )
你可以用这个:
new SolidBrush(color)
颜色是这样的:
Color.Red
or
Color.FromArgb(36,97,121))
或者..。
If you happen to be working with a application which has a mix of Windows Forms and WPF you might have the additional complication of trying to convert a System.Drawing.Color to a System.Windows.Media.Color. 我不知道是否有更简单的方法,但我是这样做的:
System.Drawing.Color MyColor = System.Drawing.Color.Red; System.Windows.Media.Color = ConvertColorType(MyColor); System.Windows.Media.Color ConvertColorType(System.Drawing.Color color) { byte AVal = color.A; byte RVal = color.R; byte GVal = color.G; byte BVal = color.B; return System.Media.Color.FromArgb(AVal, RVal, GVal, BVal); }
然后,您可以使用前面提到的技术之一转换为画笔。
通常使用兄弟或父亲的画笔就足够了,在 wpf 中可以通过检索前景或背景属性轻松实现这一点。

我以前也遇到过同样的问题,这是我的课程,它解决了颜色转换问题 Use it and enjoy :
在这里你去,使用我的类多色转换
using System; using System.Windows.Media; using SDColor = System.Drawing.Color; using SWMColor = System.Windows.Media.Color; using SWMBrush = System.Windows.Media.Brush; //Developed by امین امیری دربان namespace APREndUser.CodeAssist { public static class ColorHelper { public static SWMColor ToSWMColor(SDColor color) => SWMColor.FromArgb(color.A, color.R, color.G, color.B); public static SDColor ToSDColor(SWMColor color) => SDColor.FromArgb(color.A, color.R, color.G, color.B); public static SWMBrush ToSWMBrush(SDColor color) => (SolidColorBrush)(new BrushConverter().ConvertFrom(ToHexColor(color))); public static string ToHexColor(SDColor c) => "#" + c.R.ToString("X2") + c.G.ToString("X2") + c.B.ToString("X2"); public static string ToRGBColor(SDColor c) => "RGB(" + c.R.ToString() + "," + c.G.ToString() + "," + c.B.ToString() + ")"; public static Tuple<SDColor, SDColor> GetColorFromRYGGradient(double percentage) { var red = (percentage > 50 ? 1 - 2 * (percentage - 50) / 100.0 : 1.0) * 255; var green = (percentage > 50 ? 1.0 : 2 * percentage / 100.0) * 255; var blue = 0.0; SDColor result1 = SDColor.FromArgb((int)red, (int)green, (int)blue); SDColor result2 = SDColor.FromArgb((int)green, (int)red, (int)blue); return new Tuple<SDColor, SDColor>(result1, result2); } } }
Here is the Easiest way, No Helpers, No Converters, No weird Media references. Just 1 line:
System.Drawing.Brush _Brush = new SolidBrush(System.Drawing.Color.FromArgb(this.ForeColor.R, this.ForeColor.G, this.ForeColor.B));
