如何为wpf窗口的背景颜色定义静态资源？ [英] How to define static resource for background color of wpf window?

问题描述

大家好，

我在window.resource中编写LinearGradientBrush代码，如下所示

  <   Window.Resources  >  
 <   LinearGradientBrush     x：密钥  =  cbColor >  
 <   GradientStop    偏移量  =  0 < span class =code-attribute>  颜色  = 红色 >  <   / GradientStop  >  
 <   GradientStop     Offset   =  0.5   颜色  = 银 >  <   / GradientStop  >  
 <   GradientStop    偏移量  =  1   颜色  = 绿色 >  <   / GradientStop  >  
 
 <   / LinearGradientBrush  >  
 
 <   /Window.Resources  >  
 

并将其作为背景使用窗口作为一个静态资源，但它给出了一些错误。

如果我使用它作为一个动态资源它工作正常，我很困惑为什么它不使用静态资源，因为我只写它在窗口xaml代码



我尝试过：



i试图使用静态资源标记

解决方案

对StackOverflow上的问题有一个很好的解释：

c＃ - ResourceDictionary的Windows样式不适用 - 堆栈溢出 [ ^ ]



基本上，窗口是在嵌套<$ c $之前创建的c> ResourceDictionary 已处理完毕。此时，< Window.Resources> 字典中没有定义任何内容。



如果使用 StaticResource ，设计器将失败，应用程序将崩溃。



如果您使用 DynamicResource ，最初将创建窗口而不应用资源;一旦处理了嵌套的 ResourceDictionary ，并且其资源可用，窗口样式将会更新。



更好的解决方案是将资源移动到< Application.Resources> 字典，在创建窗口之前 处理。

hi all,
im writing LinearGradientBrush code in window.resource like below

<Window.Resources>
 <LinearGradientBrush x:Key="cbColor">
           <GradientStop Offset="0" Color="Red"></GradientStop>
           <GradientStop Offset="0.5" Color="Silver"></GradientStop>
           <GradientStop Offset="1" Color="Green"></GradientStop>

 </LinearGradientBrush>

   </Window.Resources>

and using this as a background of window as a static resource but it is giving some error.
and if am using it as a dynamic resource it working fine,im confused why it is not working with static resource as i am writing it only in window xaml code

What I have tried:

i tried to write in window.resource with static resource tag

解决方案

There's a good explanation of the problem on StackOverflow:
c# - Windows Style from ResourceDictionary don't apply - Stack Overflow[^]

Basically, the Window is created before the nested ResourceDictionary is processed. At that point, nothing defined in the <Window.Resources> dictionary is available.

If you use a StaticResource, the designer will fail and the application will crash.

If you use a DynamicResource, the window will initially be created without the resource being applied; once the nested ResourceDictionary has been processed, and its resources are available, the window style will be updated.

A better solution is to move your resources to the <Application.Resources> dictionary, which is processed before the window is created.
