Methods
| Name | Description | |

|
CheckAccess | Determines whether the calling thread has access to this object. (Inherited from DependencyObject.) |
|
ClearValue | Clears the local value of a dependency property. (Inherited from DependencyObject.) |
|
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |

Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
|
GetAnimationBaseValue | Returns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.) |
|
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
GetValue | Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.) |
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
ReadLocalValue | Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.) |
|
SetValue | Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.) |
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |

Remarks
Geometries can be used individually or in combination to declare the data for a Path.
FillRule is technically a property inherited from the base Geometryclass, but setting it has no effect on an EllipseGeometry.
EllipseGeometry Compared to Ellipse
The Ellipse class has a Fill, Stroke, and other rendering properties that EllipseGeometry lacks.
The EllipseGeometry class simply defines the geometry of an ellipse, and cannot render itself. Because of its simplicity, it has a wider range of uses.
Examples
The following example shows how to create an ellipse using EllipseGeometry.
<Canvas>
<Path Fill="Gold" Stroke="Black" StrokeThickness="1">
<Path.Data>
<EllipseGeometry Center="50,50" RadiusX="50" RadiusY="50" />
</Path.Data>
</Path>
</Canvas>
The following illustration shows the output from the example.
