我有一个样式具有名为“Fill”的setter属性,并将DrawingBrush作为其值。我想从中提取DrawingBrush以在viewmodel中使用。这是我的风格。
<Style x:Key="ICON_STYLE" TargetType="Rectangle">
<Setter Property="Fill">
<Setter.Value>
<DrawingBrush Viewbox="0,0,39.125,39.125" ViewboxUnits="Absolute">
<DrawingBrush.Drawing>
<GeometryDrawing Brush="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=uiEntityViews:ViewModel}, Path=MeSiteColor}" Geometry="F1M19.5625,0.999954C29.8144,0.999954 38.125,9.31053 38.125,19.5625 38.125,29.8142 29.8143,38.1249 19.5625,38.1249 9.31073,38.1249 1,29.8142 1,19.5625 1,9.31053 9.31064,0.999954 19.5625,0.999954z">
<GeometryDrawing.Pen>
<Pen DashCap="Square" EndLineCap="Flat" LineJoin="Round" MiterLimit="10" StartLineCap="Flat" Thickness="2">
<Pen.Brush>
<LinearGradientBrush EndPoint="0.849422,0.849423" StartPoint="0.150577,0.150578">
<GradientStop Color="#FF657783" Offset="0"/>
<GradientStop Color="White" Offset="0.146"/>
<GradientStop Color="#FF2C4758" Offset="1"/>
</LinearGradientBrush>
</Pen.Brush>
<Pen.DashStyle>
<DashStyle/>
</Pen.DashStyle>
</Pen>
</GeometryDrawing.Pen>
</GeometryDrawing>
</DrawingBrush.Drawing>
</DrawingBrush>
</Setter.Value>
</Setter>
</Style>
我想提取DrawingBrush如下 -
if (resourceObject is Style)
{
Style iconStyle = resourceObject as Style;
var collections = iconStyle.Setters;
// How to extract iconBrush from collections????
DrawingBrush iconBrush = ???
}
答案 0 :(得分:3)
以下可能有效:
DrawingBrush iconBrush = GrabFirstDrawingBrushInStyle(resourceObject as Style);
private DrawingBrush GrabFirstDrawingBrushInStyle(Style style)
{
if (style != null)
{
foreach (var setter in style.Setters.OfType<Setter>())
{
if (setter.Value is DrawingBrush)
return (DrawingBrush)setter.Value;
}
}
return null;
}
