Method Crosses
Crosses(Geometry, Geometry)
Returns true if geometry1 crosses geometry2.
Declaration
public static bool Crosses(this Geometry geometry1, Geometry geometry2)Parameters
| Type | Name | Description |
|---|---|---|
| Geometry | geometry1 | The first geometry to calculate intersection with. |
| Geometry | geometry2 | The second geometry to calculate intersection with. |
Returns
| Type | Description |
|---|---|
| System.Boolean |

Remarks
This method is one of several that determines the spatial relationship between two geometries. If the spatial relationship exists between the two input geometries then true is returned. If the spatial relationship does not exist between the two input geometries then false is returned. The spatial relationship test used by this method is based on the Dimensionally Extended 9 Intersection Model (DE-9IM) developed Clementini, et al., and is discussed further in the web pages: DE-9IM and Understanding spatial relations.
The GeometryEngine.Crosses Method returns true if an intersection results in a geometry whose dimension is one less than the maximum dimension of the two source geometries and the intersection set is interior to both source geometries. This method returns true only for the following combinations of geometries: MultiPoint/Polygon, MultiPoint/Polyline, Polyline/Polyline, and Polyline/Polygon comparisons. The following is a visual example of when this method returns true:
Supports true curves.
