c# - How to set default value instead of null in deserialization -

-

after deserialization object null, cause exception in deserialization i've avoided problem setting appropriate property in class:

[jsonproperty("jerseynumber", nullvaluehandling = nullvaluehandling.ignore)] public int jerseynumber { get; set; }

the problem after deserialization, value of int equal 0 because in json null.
want set null value empty, how can achieve this?
i've tryed with: [defaultvalue("null")] don't working because value integer.

set int nullable try following:

public int? jerseynumber { get; set; }
