static member GetChild : 
        reference:DependencyObject *
        childIndex:int -> DependencyObject

The parent visual, referenced as a DependencyObject.

Type: System.Int32

The index that represents the child visual that is contained by reference.

Return Value

Type: System.Windows.DependencyObject

The index value of the child visual object.

Call the GetChildrenCount method to determine the total number of child elements of a parent visual.

The value of reference can represent either a Visual or Visual3D object, which is why the common base type DependencyObject is used here as a parameter type.

The following example shows how to enumerate all the descendants of a visual object. This is a technique you might use if you are interested in serializing all the rendering information of a visual object hierarchy or are performing analysis or alternative rendering.
