Method Touches
Touches(Geometry, Geometry)
Returns true if geometry1 touches geometry2.
Declaration
public static bool Touches(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.Touches Method returns true if the two geometries have at least one boundary point in common, but no interior points. The following is a visual example of when this method returns true:
Supports true curves.
