【问题描述】：

如何在这两种颜色类型之间进行转换？

【问题讨论】：

System.Drawing.Color => System.Windows.Media.Color 的可能重复项

【参考方案1】：

您可以在下面查看两种转换方向的示例：

Drawing.Color 到 Windows.Media.Color

// This is your color to convert from
System.Drawing.Color color; 
System.Windows.Media.Color newColor = System.Windows.Media.Color.FromArgb(color.A, color.R, color.G, color.B);

Windows.Media.Color 到 Drawing.Color

// This is your color to convert from
System.Windows.Media.Color color; 
System.Drawing.Color newColor = System.Drawing.Color.FromArgb(color.A, color.R, color.G, color.B);

【参考方案2】：

...或使用@Rion Williams 回答作为扩展名：

public static System.Windows.Media.Brush ToBrush(this System.Drawing.Color color)

    return new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(color.A, color.R, color.G, color.B));

【参考方案3】：

为了经常使用，我建议这样的助手：

using SDColor = System.Drawing.Color;
using SWMColor = System.Windows.Media.Color;

namespace ColorHelper

    public static class ColorExt
    
        public static SWMColor ToSWMColor(this SDColor color) => SWMColor.FromArgb(color.A, color.R, color.G, color.B);
        public static SDColor ToSDColor(this SWMColor color) => SDColor.FromArgb(color.A, color.R, color.G, color.B);
    

【参考方案4】：

这是我用的：

using System.Runtime.CompilerServices;
using System.Windows.Media;

namespace HQ.Wpf.Util

    public static class ColorExtension
    
        /// <summary>
        /// Convert Media Color (WPF) to Drawing Color (WinForm)
        /// </summary>
        /// <param name="mediaColor"></param>
        /// <returns></returns>
        [MethodImpl(MethodImplOptions.AggressiveInlining)]
        public static System.Drawing.Color ToDrawingColor(this System.Windows.Media.Color mediaColor)
        
            return System.Drawing.Color.FromArgb(mediaColor.A, mediaColor.R, mediaColor.G, mediaColor.B);
        

        /// <summary>
        /// Convert Drawing Color (WPF) to Media Color (WinForm)
        /// </summary>
        /// <param name="drawingColor"></param>
        /// <returns></returns>
        [MethodImpl(MethodImplOptions.AggressiveInlining)]
        public static System.Windows.Media.Color ToMediaColor(this System.Drawing.Color drawingColor)
        
            return System.Windows.Media.Color.FromArgb(drawingColor.A, drawingColor.R, drawingColor.G, drawingColor.B);
