Gets a copy of the Point at the specified index.

Syntax

public Point GetPoint( int pointIndex ) |

Public Function GetPoint ( _ pointIndex As Integer _ ) As Point |
Parameters
- pointIndex
- Type: System..::.Int32
The index of the Point to retrieve.
Return Value
A copy of the point.Examples
The code below shows two alternative ways to iterate through the Points comprising a Multipoint; firstly by using
GetPoint and PointCount to enumerate over each vertex in a Multipoint by point index number, and secondly by using
a foreach (For Each in Visual Basic) statement and the GetPoints method.
The code assumes there is an existing Multipoint called mpt.
Instances of the Point class are fully-qualified to avoid namespace clashes with System.Drawing.Point.

// For an existing single part Multipoint called mpt, GetPoint and PointCount can be used to iterate points by index number. for (int pointIndx = 0; pointIndx < mpt.PointCount; pointIndx++) { // Use GetPoint to get a copy of the specific point. System.Diagnostics.Debug.WriteLine(mpt.GetPoint(pointIndx).ToString()); } // Alternatively, Points can be iterated by using foreach. foreach (ESRI.ArcGISExplorer.Geometry.Point pt in mpt.GetPoints()) { System.Diagnostics.Debug.WriteLine(pt.ToString()); }
