In This Topic
    ToGeometry Method (MultipointBuilderEx)
    In This Topic
    Returns a Multipoint instance representing the current state of the builder.
    Syntax
    public new Multipoint ToGeometry()
    Public Shadows Function ToGeometry() As Multipoint

    Return Value

    Example
    Construct a Multipoint - from an enumeration of MapPoints
    // Use a builderEx convenience method or use a builderEx constructor.
    
    List<MapPoint> list = new List<MapPoint>();
    list.Add(MapPointBuilderEx.CreateMapPoint(1.0, 1.0));
    list.Add(MapPointBuilderEx.CreateMapPoint(1.0, 2.0));
    list.Add(MapPointBuilderEx.CreateMapPoint(2.0, 2.0));
    list.Add(MapPointBuilderEx.CreateMapPoint(2.0, 1.0));
    
    // use the builderEx constructors which don't need to run on the MCT.
    // use AttributeFlags.NoAttributes since we have 2d points in the list
    MultipointBuilderEx builderEx = new MultipointBuilderEx(list, AttributeFlags.None);
    Multipoint multiPoint = builderEx.ToGeometry() as Multipoint;
    int ptCount = builderEx.PointCount;
    
    // builderEx convenience methods don't need to run on the MCT
    multiPoint = MultipointBuilderEx.CreateMultipoint(list);
    // multiPoint.HasZ, HasM, HasID will be false - the attributes are determined 
    //    based on the attribute state of the points in the list
    
    // or specifically set the state
    multiPoint = MultipointBuilderEx.CreateMultipoint(list, AttributeFlags.None);
    // multiPoint.HasM = false
    
    multiPoint = MultipointBuilderEx.CreateMultipoint(list, AttributeFlags.HasM);
    // multiPoint.HasM = true
    
    ptCount = multiPoint.PointCount;
    
    Modify the points of a Multipoint
    // assume a multiPoint has been built from 4 points
    // the modified multiPoint will have the first point removed and the last point moved
    
    // use the builderEx constructors which don't need to run on the MCT.
    MultipointBuilderEx builderEx = new MultipointBuilderEx(multipoint);
    // remove the first point
    builderEx.RemovePoint(0);
    // modify the coordinates of the last point
    var ptEx = builderEx.GetPoint(builderEx.PointCount - 1);
    builderEx.RemovePoint(builderEx.PointCount - 1);
    
    var newPtEx = MapPointBuilderEx.CreateMapPoint(ptEx.X + 1.0, ptEx.Y + 2.0);
    builderEx.AddPoint(newPtEx);
    Multipoint modifiedMultiPointEx = builderEx.ToGeometry() as Multipoint;
