如何将自定义属性设置为 XAML 值?

发布于 2024-08-09 08:02:04 字数 1476 浏览 8 评论 0原文

我有这个带有自定义颜色属性的库。我希望能够在 XAML 中使用这些属性,如下所示:

    <Style TargetType="{x:Type eg:MyWindow}">
        <Setter Property="Background">
            <Setter.Value>
                <SolidColorBrush Color="CustomClass.CustomColorProperty"/>
            </Setter.Value>
        </Setter>
    </Style>

包含 CustomClass 的命名空间已被引用。我该怎么办?谢谢。

编辑:

我刚刚注意到 CustomClass 是静态的,因此我无法在 XAML 中创建它的实例。另外,当我输入 eg: 时,CustomClass 不会显示在智能感知中。如果我有一个实例类,我无法让您的任何解决方案起作用,即使它们应该起作用。对于这种情况有解决方法吗?

编辑2:

这是实际的类和命名空间:

namespace Assergs.Windows
{
    public static class OfficeColors
    {
        public class Background
        {
            public static Color OfficeColor1 = (Color)ColorConverter.ConvertFromString("#e4e6e8");
            public static Color OfficeColor2 = (Color)ColorConverter.ConvertFromString("#dce0ed");
            public static Color OfficeColor3 = (Color)ColorConverter.ConvertFromString("#a8c3e0");
        }
    }
}

这是XAML命名空间:

xmlns:aw="clr-namespace:Assergs.Windows;assembly=Assergs.Windows"

如果我按照Zenuka的建议使用这一行:

<SolidColorBrush Color="{x:Static aw:OfficeColors.Background.OfficeColor1}"/>

它会在编译时抛出此错误:

Cannot find the type 'OfficeColors.Background'. Note that type names are case sensitive.

I have this library with custom Color properties. I wanna be able to use these properties in XAML like this:

    <Style TargetType="{x:Type eg:MyWindow}">
        <Setter Property="Background">
            <Setter.Value>
                <SolidColorBrush Color="CustomClass.CustomColorProperty"/>
            </Setter.Value>
        </Setter>
    </Style>

The namespace that contains CustomClass is already referenced. How should I go about this? Thanks.

EDIT:

I just noticed that CustomClass is static, so I can't create an instance of it in XAML. Also, when I type eg:, CustomClass doesn't show up in intellisense. I can't get any of your solutions to work, even though they should, if I had an instance class. Is there a workaround for this situation?

EDIT 2:

This is the actual class and namespace:

namespace Assergs.Windows
{
    public static class OfficeColors
    {
        public class Background
        {
            public static Color OfficeColor1 = (Color)ColorConverter.ConvertFromString("#e4e6e8");
            public static Color OfficeColor2 = (Color)ColorConverter.ConvertFromString("#dce0ed");
            public static Color OfficeColor3 = (Color)ColorConverter.ConvertFromString("#a8c3e0");
        }
    }
}

And this is the XAML namespace:

xmlns:aw="clr-namespace:Assergs.Windows;assembly=Assergs.Windows"

And if I use this line, as suggested by Zenuka:

<SolidColorBrush Color="{x:Static aw:OfficeColors.Background.OfficeColor1}"/>

It throws this error at compile time:

Cannot find the type 'OfficeColors.Background'. Note that type names are case sensitive.

使用这个:

<SolidColorBrush Color="{x:Static aw:OfficeColors+Background.OfficeColor1}"/>

注意使用 + 号而不是点来引用嵌套类

Use this:

<SolidColorBrush Color="{x:Static aw:OfficeColors+Background.OfficeColor1}"/>

Notice the + sign instead of a dot to reference nested classes

我假设您在 CustomClass 上有一个静态属性?
然后你可以使用:

<SolidColorBrush Color="{x:Static eg:CustomClass.CustomColorProperty}"/>

但也许你需要更改名称空间前缀...

编辑:
问题出在因为你在另一个类中声明一个类......
我建议您将 Backgroud 类移到 OfficeColors 类之外并将其声明为静态,或者将 Background 类的属性移至 OfficeColors 类(可能带有 Background 前缀),或者在您尝试时使用命名空间。

玩得开心:)

编辑2:
使用 Nir ​​的方法,使用 + 号“aw:OfficeColors+Background.OfficeColor1”来引用嵌套类,我不知道:)

I'm asuming you have a Static property on the CustomClass?
Then you could use:

<SolidColorBrush Color="{x:Static eg:CustomClass.CustomColorProperty}"/>

but maybe you need to change the namespace prefix...

EDIT:
The problem lies because you're declaring a class in another class...
I suggest you move the class Backgroud outside of the OfficeColors class and declare it static or move the Properties of the Background Class to the OfficeColors class (maybe with a Background prefix), OR use namespaces as you are kind of trying.

Have fun :)

EDIT2:
Use Nir's method using the + sign 'aw:OfficeColors+Background.OfficeColor1' to reference nested classes, didn't know that one :)

您必须将类的实例声明为资源之一。 (假设 CustomColorProperty 不是静态的)

<CustomNamespace.CustomClass x:Key=CcInstance />
<Style TargetType="{x:Type eg:MyWindow}">        
     <Setter Property="Background">            
         <Setter.Value>                
              <SolidColorBrush Color="{Binding Source={StaticResource CcInstance}, Path=CustomColorProperty} />            
         </Setter.Value>        
     </Setter>    
</Style>

You would have to declare an instance of the class as one of the resources. (Assuming CustomColorProperty is not static)

<CustomNamespace.CustomClass x:Key=CcInstance />
<Style TargetType="{x:Type eg:MyWindow}">        
     <Setter Property="Background">            
         <Setter.Value>                
              <SolidColorBrush Color="{Binding Source={StaticResource CcInstance}, Path=CustomColorProperty} />            
         </Setter.Value>        
     </Setter>    
</Style>
