ArcGIS.Core.Geometry Namespace / PolygonBuilderEx Class / PolygonBuilderEx Constructor / PolygonBuilderEx Constructor(Polygon)
Polygon used for construction of the geometry of this builder.
Example

In This Topic
    PolygonBuilderEx Constructor(Polygon)
    In This Topic
    Initializes a new instance of the PolygonBuilderEx class from the input polygon.
    Syntax
    public PolygonBuilderEx( 
       Polygon polygon
    )
    Public Function New( _
       ByVal polygon As Polygon _
    )

    Parameters

    polygon
    Polygon used for construction of the geometry of this builder.
    Exceptions
    ExceptionDescription
    The input polygon is null.
    Remarks
    All properties of the input polygon, including the spatial reference, are inherited by the new builder.
    Example
    Builder Properties
    // list of points

      MapPointBuilderEx.CreateMapPoint(1, 1, 5, 6),
      MapPointBuilderEx.CreateMapPoint(2, 1, 6),
      MapPointBuilderEx.CreateMapPoint(0, 0)
