Populates the array with references to a sub-sequence of geometries.
[Visual Basic .NET] Public Sub QueryGeometries ( _ ByVal pGeometryCollection As IGeometryCollection, _ ByVal Index As Integer, _ ByRef geometries As IGeometry[] _ )
[C#] public void QueryGeometries ( IGeometryCollection pGeometryCollection, int Index, ref IGeometry[] geometries );
[C++]
HRESULT QueryGeometries(
IGeometryCollection* pGeometryCollection,
long Index,
Array* geometries
);
[C++]
Parameters pGeometryCollection [in]
pGeometryCollection is a parameter of type IGeometryCollection Index Index is a parameter of type long geometries [in, out] geometries is a parameter of type Array
All development languages compatible version of IGeometryCollection::QueryGeometries.
