Version

AddSegments(Int32,IEnumerable<Segment>) Method
Adds segments to the MultipartBuilderEx. The segments will be added to the end of the Parts list.
Syntax
public void AddSegments( 
   int partIndex,
   IEnumerable<Segment> segments
)

Parameters

partIndex
The index of the part to which the segments will be added. The segments are added to the end of the part.
segments
An enumeration of segments.
Exceptions
ExceptionDescription
segments is null.
partIndex is greater than PartCount - 1 or PartCount == 0 and part index is greater than 0.
Remarks
The spatial reference of each segment is ignored, and the attribute of each segment does not affect the attribute awareness of the builder. However, if the builder has an attribute and the start or end point of a segment also has that attribute, then the attribute value will be taken from the point. If the point doesn't have that attribute, then a default value will be set in the builder. For example, suppose the HasZ property of the builder is set to true. If the HasZ property of a point is set to true, then the point's Z-value is used. Otherwise, the default value is used. The default value for Z is 0, for M is NaN and for ID is 0.If partIndex == 0 and PartCount == 0, then a new part is created. If partIndex is less than zero, then the segments are added to the last part.
