Populates an array with references to points in the Multipoint. The QueryPoints method on IPointCollection makes copies of the points.
[Visual Basic .NET] Public Sub GetPoints ( _ ByVal pPointCollection As IPointCollection4, _ ByVal Index As Integer, _ ByRef Points As IPoint[] _ )
[C#] public void GetPoints ( IPointCollection4 pPointCollection, int Index, ref IPoint[] Points );
[C++]
HRESULT GetPoints(
IPointCollection4* pPointCollection,
long Index,
Array* Points
);
[C++]
Parameters pPointCollection [in]
pPointCollection is a parameter of type IPointCollection4 Index Index is a parameter of type long Points [in, out] Points is a parameter of type Array
All development languages compatible version of IPointCollection::GetPoints .
public void GetPoints()
{
//prepare inputPoints
IPoint point1=new PointClass();
point1.PutCoords(10, 10);
IPoint point2=new PointClass();
point2.PutCoords(20, 20);
IPoint[] inputPointArray=new IPoint[2];
inputPointArray[0]=point1;
inputPointArray[1]=point2;
IPointCollection4 pointCollection=new MultipointClass();
//add points to pointCollection
IGeometryBridge geometryBridge=new GeometryEnvironmentClass();
geometryBridge.AddPoints(pointCollection, ref inputPointArray);
//get Points

for (int i=0; i < outputPointArray.Length; i++)
{

if (currentPoint == null)
{
System.Windows.Forms.MessageBox.Show("Current point=null");
}
else
{
