Method NearestVertex
NearestVertex(Geometry, MapPoint)
Returns a ProximityResult that describes the nearest vertex in the input geometry to the input point.
Declaration
public static ProximityResult? NearestVertex(this Geometry geometry, MapPoint point)Parameters
| Type | Name | Description |
|---|---|---|
| Geometry | geometry | The geometry in which the nearest vertex to a specified point is to be found. |
| MapPoint | point | The point which to find the nearest vertex to. |
Returns
| Type | Description |
|---|---|
| ProximityResult | The proximity result. |
Remarks
If the specified geometry is a polyline or polygon the nearest vertex is the closest ending position of the line segment that comprises geometry; it may not necessarily be the closest point of the line segment. If you want to obtain the closest point in the polyline or polygon use the NearestCoordinate(Geometry, MapPoint) Method instead.
If the specified geometry is an envelope, the geometry will first be converted to a Polygon to perform the calculation of the nearest coordinate. The final PartIndex will always be invalid for an envelope.
Input geometries with true curves (where HasCurves is true) are
supported, although curve segments do not affect the return value.
