请考虑以下代码

 var currentType = Type.GetType("Some.Type, Some");
 dynamic myDynamic = new System.Dynamic.ExpandoObject();
 myDynamic.A = "A";
 var objectInCorrectType = ???

如何将动态转换为currentType？

我正在尝试在故事板完成后运行一些代码，但似乎找不到如何设置的代码...

Completed="LoadingStoryBoard_Completed"

在情节提要元素上，我收到错误消息“无法在样式的目标标签上指定事件'已完成'。请改用EventSetter。” 但是，很难找到有关如何使用事件设置器的良好参考。

Xaml代码如下所示（其结构如下：当图像可见时，它可以启动）

<Window.Resources>
    <Style x:Key="AnimationImageStyle" TargetType="{x:Type Image}">
        <Style.Triggers>

             Value="True">
