C# 以编程方式反转静态资源字典颜色wpf

我的调色板.xaml文件中有以下颜色，我很想知道

我是否可以通过编程在资源字典中循环颜色并反转颜色值

类似于在photoshop中拍摄图像并添加反转过滤器。我这样做是因为我不希望在手动反转颜色的情况下复制xaml文件。我宁愿它是一个更程序化的解决方案

<Color x:Key="Accent01">#1d7b87</Color>
<Color x:Key="Accent02">#28aabc</Color>

<Color x:Key="ColorWhite">White</Color>
<Color x:Key="ColorBlack">Black</Color>

<Color x:Key="Color01">#e0e0e0</Color>
<Color x:Key="Color02">#c3c5c7</Color>
<Color x:Key="Color03">#a6a9ad</Color> 
<Color x:Key="Color04">#8b8f94</Color>
<Color x:Key="Color05">#71757a</Color>
<Color x:Key="Color06">#585c61</Color>
<Color x:Key="Color07">#404347</Color>
<Color x:Key="Color08">#292b2e</Color>
<Color x:Key="Color09">#1e1f21</Color>
<Color x:Key="Color10">#121314</Color>

加载目录后，您可以在其项上循环，并使用keys属性更改其值。它应该是这样的：

foreach(object keyy in RescourcesDir.Keys)
{
    //get the object and it's value
    object val = RescourcesDir[keyy];
    //change it's value ...
    RescourcesDir[keyy] = somevalue;
}

如果您不介意更改值，Ahmad的解决方案非常好。但是，如果您想保留原始值并使用反向版本，该怎么办

假设您有一个名为Converters的文件夹，并在其中创建以下两个

IValueConverter

类：

将

System.Windows.Media.Color

转换为

System.Windows.Media.SolidColorBrush

的基类：

using System;
using System.Globalization;
using System.Windows.Data;
using System.Windows.Media;

namespace WPFTest.Converters
{
  public class ColorToBrush : IValueConverter
  {
    public virtual object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
      return value is Color ? new SolidColorBrush((Color)value) : Brushes.Black;
    }

    public virtual object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
      throw new NotImplementedException();
    }
  }
}

用于反转颜色的继承类--然后将其转换为画笔：

using System;
using System.Globalization;
using System.Windows.Media;

namespace WPFTest.Converters
{
  public class InvertColorToBrush : ColorToBrush
  {
    public override object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
      if (value is Color)
      {
        Color color = (Color)value;
        int iCol = ((color.A << 24) | (color.R << 16) | (color.G << 8) | color.B) ^ 0xffffff;
        Color inverted = Color.FromArgb((byte)(iCol >> 24),
                                        (byte)(iCol >> 16),
                                        (byte)(iCol >> 8),
                                        (byte)(iCol));

        return base.Convert(inverted, targetType, parameter, culture);
      }
      else
      {
        return Brushes.Black;
      }
    }

    public override object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
      throw new NotImplementedException();
    }
  }
}

申报您的钥匙：

<converters:ColorToBrush x:Key="BrushColor" />
<converters:InvertColorToBrush x:Key="BrushInvertColor" />

使用方法：

<Label
  Content="COLOR TEST"
  Background="{Binding Converter={StaticResource BrushColor}, Mode=OneWay, Source={StaticResource Blue}}"
  Foreground="{Binding Converter={StaticResource BrushColor}, Mode=OneWay, Source={StaticResource Yellow}}"/>

<Label
  Content="COLOR INVERT TEST"
  Background="{Binding Converter={StaticResource BrushInvertColor}, Mode=OneWay, Source={StaticResource Blue}}"
  Foreground="{Binding Converter={StaticResource BrushInvertColor}, Mode=OneWay, Source={StaticResource Yellow}}"/>

<converters:ColorToBrush x:Key="BrushColor" />
<converters:InvertColorToBrush x:Key="BrushInvertColor" />

<Label
  Content="COLOR TEST"
  Background="{Binding Converter={StaticResource BrushColor}, Mode=OneWay, Source={StaticResource Blue}}"
  Foreground="{Binding Converter={StaticResource BrushColor}, Mode=OneWay, Source={StaticResource Yellow}}"/>

<Label
  Content="COLOR INVERT TEST"
  Background="{Binding Converter={StaticResource BrushInvertColor}, Mode=OneWay, Source={StaticResource Blue}}"
  Foreground="{Binding Converter={StaticResource BrushInvertColor}, Mode=OneWay, Source={StaticResource Yellow}}"/>
