ArcGIS.Core.Geometry Namespace / MultipointBuilderEx Class / AddPoint Method / AddPoint(MapPoint) Method
The MapPoint to add. It cannot be null.
Example

In This Topic
    AddPoint(MapPoint) Method
    In This Topic
    Add a MapPoint to the list of points.
    Syntax
    public void AddPoint( 
       MapPoint point
    )
    Public Overloads Sub AddPoint( _
       ByVal point As MapPoint _
    ) 

    Parameters

    point
    The MapPoint to add. It cannot be null.
    Exceptions
    ExceptionDescription
    The input point is null.
    Remarks
    The XY-values of the point are added to the end of the Coordinate2Ds list. If the point property HasZ is true, and this builder property HasZ is true, then the Z-value of the point is added to the end of the Zs list. The same is true for Ms and IDs. If the point is missing any of the attributes (Z, M, or ID) that are present in this builder, a default value is used. The default value for Z is zero, M is NaN, and ID is zero. If a point has an attribute that is missing in the builder, the attribute is ignored.
    Example
    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;
