c# - 从 WPF 中的 dll 设置窗口图标

Question

我想从 dll 设置我的窗口图标，但它抛出错误。

我在 JIMS.Resources.dll 中有一个名为 JIMS.ico 的图标，我在窗口中将其用作

<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>

但是它抛出异常

尝试以下操作:

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

为此，图标必须构建为资源
