</ResourceDictionary>

2.App.Xmal中添加创建的字典

<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Dictionary1.xaml"></ResourceDictionary>
<ResourceDictionary Source="Dictionary2.xaml"></ResourceDictionary>

</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>

3.动态添加按钮的方法

private void GetUiElement_F()
{
//Uri resourceUri = new Uri("Images/logo.png", UriKind.Relative);
//StreamResourceInfo streamInfo = Application.GetResourceStream(resourceUri);

//BitmapFrame temp = BitmapFrame.Create(streamInfo.Stream);
//var brush = new ImageBrush();
//brush.ImageSource = temp;
var tb = new Button
{
VerticalAlignment = VerticalAlignment.Top,
HorizontalAlignment = HorizontalAlignment.Left,
FontSize = 11,
FontWeight = FontWeights.Bold,
Foreground = Brushes.Transparent,
Width = 100,
Height = 100,
Margin = new Thickness(10),
};
// logo.RegisterName("btn1", tb);
tb.SetResourceReference(StyleProperty, "GlassYButton");
// tb.Background = brush;
tb.Click += new RoutedEventHandler(btnEvent_Click);
logo.Children.Add(tb);
}
