IGeometryBridge.GetPoints Method

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

Description

All development languages compatible version of IPointCollection::GetPoints .

[C#]

    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
        int index=0;
        IPoint[] outputPointArray=new IPoint[inputPointArray.Length - index];
        geometryBridge.GetPoints(pointCollection, index, ref outputPointArray);
        for (int i=0; i < outputPointArray.Length; i++)
        {
            IPoint currentPoint=outputPointArray[i];
            if (currentPoint == null)

            }
            else
            {
                System.Windows.Forms.MessageBox.Show("X=" + currentPoint.X + ", Y=" + currentPoint.Y);
