ThrowCorruptedShapefileDataException thrown when data is not corrupted when consumed by other software

[bjusticebuxton]

Hello! I'm sorry, I'm not very experienced working with shapefiles so I'm not sure if I'm going to properly explain my problem. I am calling Shapefile.ReadAllFeatures(filepath)using GeometryBuilderMode.IgnoreInvalidShapes on the attached file, and I'm hitting ThrowCorruptedShapefileDataException(). I tried parsing through it a few different ways and it looks like it's throwing the error on the 495th record in the file. This exception mentions that there must be a 1-to-1 relationship between geometries and attributes, however if I instantiate a ShapefilePolygonReader and a DbfReader pointing to the appropriate files, they both show equal values as their respective RecordCount properties. I'm not sure what is causing the exception.

A couple of other pieces of software that read shapefiles are able to parse this correctly (a program called Alteryx, and NetTopologySuite.IO.Shapefile, which I an trying to port over to this library). I really like this one because it is significantly more performant, but am unable to do so yet.

Please let me know if there is any additional information I can provide to help diagnose.
