Question

我想从一个dll设置我的Window图标，但是它的抛出错误。

我在JIMS.Resources.dll中有一个名为JIMS.ico的图标，我在我的窗口中将其消耗为

<Window x:Class="JIMS.Home"        
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"                  
        Title="JIMS" WindowStyle="None" 
        Icon="/JIMS.Resources;component/JIMS.ico">
</Window>

但它抛出异常

尝试以下方法：

Icon="pack://application:,,,/JIMS.Resources;component/JIMS.ico"

这样，图标必须构建为Resource
