XAML成员资源无法识别或无法访问

Question

我尝试在鼠标悬停时设置按钮的更改图像。 我尝试过代码，但是我在对象中遇到了错误。有人能帮助我吗？ 谢谢

<Grid>
    <Page.Resources>
        <ImageBrush x:Key="Aggiungi_Ticket_normal" ImageSource="Properties/Icons/add-2-512.png" />
        <ImageBrush x:Key="Aggiungi_Ticket_hover" ImageSource="Properties/Icons/search-2-512.pngg" />

        <ControlTemplate TargetType="Button" x:Key="btnAggiungi">
            <Grid Name="button" Background="{StaticResource Aggiungi_Ticket_normal}">
                <ContentPresenter/>
            </Grid>
            <ControlTemplate.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter TargetName="button" Property="Background" Value="{StaticResource Aggiungi_Ticket_hover}" />
                </Trigger>
            </ControlTemplate.Triggers>
        </ControlTemplate>
    </Page.Resources>

    <Button Name="btnAggiungi" Template="{StaticResource btnAggiungi}" HorizontalAlignment="Left" Margin="50,56,0,0" VerticalAlignment="Top" Width="100" Height="100" Click="btnAggiungi_Click" Cursor="Hand"/>
