将Window1图标绑定到MainWindow图标

Question

我尝试了以下代码，但它不起作用。有什么建议？

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    x:Class="Window1" x:Name="Window1" Title="Window1" 
    Height="300" Width="300"
    Icon="{Binding ElementName=Application.Current.MainWindow, Path=Icon}" >

<Grid>

</Grid>

Answer 1

这应该有效：

<Window ...
   Icon="{Binding Path=MainWindow.Icon, Source={x:Static Application.Current}}">

    <Grid>

    </Grid>
</Window>
