Json.NET crashes when serializing unsigned integer (ulong) array

Question

Getting a parser error when trying to serialize a ulong array, looks like the Json.NET library isnt checking if the integer is signed or unsigned; any one know of a workaro

Answer 1

You're right, JSON.Net doesn't handle values larger than long.MaxValue in this case.

I didn't find any way to modify that behavior, except by modifying the source code of the library. As a workaround, you could deserialize it as decimal[] and then convert that into ulong[].
