Gets a copy of the Point at the specified index.

Namespace: ESRI.ArcGISExplorer.Geometry
Assembly: ESRI.ArcGISExplorer (in ESRI.ArcGISExplorer.dll) Version: 2.0.0.900 (2.0.0.900)

Syntax

C#
public Point GetPoint( int pointIndex )

Visual Basic (Declaration)
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.

CopyC#

      // 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());
      }

CopyVB.NET

' For an existing single part Multipoint called mpt, GetPoint and PointCount can be used to iterate points by index number.
Dim pointIndx As Integer = 0
While pointIndx < mpt.PointCount
    ' Use GetPoint to get a copy of the specific point.
    System.Diagnostics.Debug.WriteLine(mpt.GetPoint(pointIndx).ToString())
    System.Math.Max(System.Threading.Interlocked.Increment(pointIndx), pointIndx - 1)
End While
' Alternatively, Points can be iterated by using foreach.
For Each pt As ESRI.ArcGISExplorer.Geometry.Point In mpt.GetPoints()
    System.Diagnostics.Debug.WriteLine(pt.ToString())
