XData group code exception when casting to string #180
Description
I am getting a "System.InvalidCastException : Unable to cast object of type 'System.Double' to type 'System.String'." when trying to parse a DXF created with AutoCAD 2017. The group code in question is 1040 (see https://help.autodesk.com/view/OARX/2020/ENU/?guid=GUID-A2A628B0-3699-4740-A215-C560E7242F63) when reading XData. The error occurs on the following line.
dxf/src/IxMilia.Dxf/IDxfHasXData.cs
Line 26 in 7149f0b
The DXF lines are
