    InsertPoints(Int32,IEnumerable<MapPoint>) Method
    In This Topic
    Insert a range of points at the specified index.
    Syntax
    public void InsertPoints( 
       int index,
       IEnumerable<MapPoint> points
    )
    Public Overloads Sub InsertPoints( _
       ByVal index As Integer, _
       ByVal points As IEnumerable(Of MapPoint) _
    ) 

    Parameters

    index
    The index specifying where the points will be inserted. A negative value means that the points coordinates will be added to the end of the corresponding list. Otherwise, the value must be in the range [0, Coordinate2Ds.Count] inclusive.
    points
    The points to insert.
    Exceptions
    ExceptionDescription
    The input points enumeration is null.
    The point index is > Coordinate2Ds.Count.
    Remarks
    The XY-values of the points are inserted into 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 inserted into 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.
