使用条件 (WPF) 以编程方式更改 ImageBrush Imagesource

Question

我有这样的xaml

<Window x:Class="Imagebind.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525" Background="#FF3F3B51">
<Window.Resources>
    <Style x:Key="ButtonStyle1" TargetType="{x:Type Button}">
        <Setter Property="FocusVisualStyle">
            <Setter.Value>
                <Style>
                    <Setter Property="Control.Template">
                        <Setter.Value>
                            <ControlTemplate>
                                <Rectangle Margin="2" SnapsToDevicePixels="True" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </Setter.Value>

        <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="HorizontalContentAlignment" Value="Center"/>
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="Padding" Value="1"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" SnapsToDevicePixels="True">
                        <Border.Background>
                            <ImageBrush ImageSource="Cancel.bmp"/>
                        </Border.Background>
                        <ContentPresenter x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsDefaulted" Value="True">
                            <Setter Property="BorderBrush" TargetName="border" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
                        </Trigger>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Background" TargetName="border">
                                <Setter.Value>
                                    <ImageBrush ImageSource="Cancel (Mouseover).bmp"/>
                                </Setter.Value>
                            </Setter>
                            <Setter Property="BorderBrush" TargetName="border" Value="#FFDDDDDD">
                            </Setter>
                        </Trigger>
                        <Trigger Property="IsPressed" Value="True">
                            <Setter Property="Background" TargetName="border">
                                <Setter.Value>
                                    <ImageBrush ImageSource="Cancel (Pressed).bmp"/>
                                </Setter.Value>
                            </Setter>
                            <Setter Property="BorderBrush" TargetName="border" Value="#FF2C628B"/>
                        </Trigger>
                        <Trigger Property="ToggleButton.IsChecked" Value="True">
                            <Setter Property="Background" TargetName="border" Value="#FFBCDDEE"/>
                            <Setter Property="BorderBrush" TargetName="border" Value="#FF245A83"/>
                        </Trigger>
                        <Trigger Property="IsEnabled" Value="False">
                            <Setter Property="Background" TargetName="border" Value="#FFF4F4F4"/>
                            <Setter Property="BorderBrush" TargetName="border" Value="#FFADB2B5"/>
                            <Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="#FF838383"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>
<Button Content="" HorizontalAlignment="Left" Margin="174,226,0,0" VerticalAlignment="Top" Width="161" Height="24" Style="{DynamicResource ButtonStyle1}"/>

还有这样的c#代码

  using System.Windows;

namespace Imagebind
{
    public partial class MainWindow : Window
    {
        private string language;
        public MainWindow()
        {
    string language = "english";
            InitializeComponent();
            if (language == "english")
            {
            /* Here I need to change Imagesource of ImageBrush of 3 state buttons programmaticaly
For example this Cancel (Mouseover).bmp for Cancel(english) (Mouseover).bmp
*/
            }
        }
    }
}

所以我想要的是，如果用户使用不同的语言，界面中的所有图像都将使用我设置条件的语言。所以我需要在 c# 代码中将所有状态的按钮的所有图像更改为新的。

如果您正在尝试本地化您的应用程序，您应该考虑查看现有的库来帮助您解决问题，例如 WPFLocalizationExtension。

要回答您的直接问题，您可以将所有图像定义为静态属性或应用程序中某处的资源，并根据语言将它们分配给正确的值。如果您不需要支持在应用程序运行时更改语言，静态属性将更容易设置。

只需像这样定义属性：

internal static class Images
{
    public static Uri CancelMouseOver { get; set; }
}

像这样设置它们：

Images.CancelMouseOver = new Uri("Cancel(english) (Mouseover).bmp", UriKind.Relative);

然后像这样使用它们：

<ImageBrush ImageSource="{x:Static local:Images.CancelMouseOver}"/>
