你如何克隆在Silverlight的道路资源？(How do you clone a path re

我在我的XAML文件中定义的资源，如下所示：

 <Path x:Key="myPath"
    Data="M14.773241,18.080208 C12.373256,18.080208 10.239936,19.30687 10.239936,27.573483
    L10.239936,36.106766 C10.239936,45.440037 12.586588,46.506699 14.986573,46.506699
    C18.613216,46.506699 19.359879,42.400059 19.359879,35.3601 L19.359879,27.733482
    C19.359879,20.05353 17.386559,18.080208 14.773241,18.080208 z M14.879907,11.786915

    C2.1333201,52.799992 2.1333201,37.600086 2.1333201,32.160122 C2.1333201,28.05348

    14.879907,11.786915 z"
 />

我希望能够多这条道路（和其他几个人）的“实例”添加到一个StackPanel。当然，我不能简单地“mypath中”添加到面板上，因为它已经是另一个容器的孩子。

不过，我似乎无法能够要么克隆的路径。我试过了：

Path clone = new Path() 
{
  Data = source.Data
};

但没有运气...约值的例外是把预期范围。

最后，我想挖成source.Data（一的PathGeometry），但不包含PathFigures ......我不知道为什么，因为如果我从资源部分直接复制到面板的路径中呈现。

是什么赋予了？

谢谢，塞尔吉奥

把路径数据在一个字符串资源：

<Page.Resources>
    <system:String x:Key="PathData">
    M14.773241,18.080208 C12.373256,18.080208 10.239936,19.30687  10.239936,27.573483
    L10.239936,36.106766 C10.239936,45.440037 12.586588,46.506699 14.986573,46.506699
    C18.613216,46.506699 19.359879,42.400059 19.359879,35.3601 L19.359879,27.733482
    C19.359879,20.05353 17.386559,18.080208 14.773241,18.080208 z M14.879907,11.786915
    C17.973221,11.786915 22.293194,13.013573 24.906511,17.920212 C26.773167,21.386856
    27.519829,27.093487 27.519829,32.213455 C27.519829,34.506775 27.306496,41.706726
    24.906511,46.453365 C23.626518,49.013351 20.906536,52.799992 15.199905,52.799992
    C2.1333201,52.799992 2.1333201,37.600086 2.1333201,32.160122 C2.1333201,28.05348
    2.1333201,22.666847 4.4266391,18.453541 C5.8666301,15.840225 8.639946,11.786915
    14.879907,11.786915 z
    </system:String>
</Page.Resources>

并使用它：

<Path x:Name="Path1" Data="{StaticResource PathData}" Fill="Blue" ... />
<Path x:Name="Path2" Data="{StaticResource PathData}" Fill="Red" ... />

你需要这在你的XAML声明：

xmlns:system="clr-namespace:System;assembly=mscorlib"

如果你想通过程序生成路径中使用一个共同的路径字符串，Silverlight是缺少一点是WPF具有重要功能 - 让你不得不杂牌吧：

string pathXaml = 
@"<Path xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation""
        xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml""
        Data=""path_data_goes_here"" />";
Path path = (Path)System.Windows.Markup.XamlReader.Load(pathXaml);
