Remarks

This read-only property returns the name of the field which records the length of each feature. Only feature classes that have a ShapeType of esriGeometryPolygon or esriGeometryPolyLine have a Length field. For Line features, this field records the length of the polyline. For polygon features, this field records the perimeter of the polygon.

A null pointer will be returned if:

• the feature class does not have a shape type of esriGeometryPolygon or esriGeometryPolyLine
• the underlying database does not maintain an area field
• the feature class is a shapefile or CAD data
