ArcGIS Runtime SDK for .NET (WPF)

## PolygonIsEqual Method |

Compares two Polygon for equality. This will check for a matching SpatialReference
and the content of Parts match. The order of parts must match too.

Syntax

- other
- Type: Esri.ArcGISRuntime.GeometryGeometry

A geometry to test for equality.

Value to indicate if the two geometries are equal.

Remarks

The various geometry **IsEqual** Methods (i.e.
IsEqual(Geometry),
IsEqual(Geometry),
IsEqual(Geometry),
IsEqual(Segment),
IsEqual(Geometry),
IsEqual(Geometry),
IsEqual(Geometry),
IsEqual(Segment))
provide the most strict comparison of two geometries to ensure they are equal (aka.
identical). You can also use the Equals(Geometry, Geometry) Method
but the test for ensuring that two geometries are equal (aka. identical) is not quite as strict. The following table provides a
comparison of the geometry comparison options:

geometryA.IsEqual(geometryB) | GeometryEngine.Equals(geometryA,geometryB) |
---|---|

Type | Type |

Shape | Shape |

Orientation | Orientation |

Order of Coordinates | -- |

In a nutshell, if you need to ensure that the 'Order of Coordinates' that comprise your geometries
are exactly the same, use the various geometry **IsEqual** Methods.
