asp.net mvc - IgnoreDataMember attribute is skipping json object properties during **DE**serialization -

according docs, ignoredatamember attribute supposed considered during serialization.

from i'm seeing, however, mvc model binding using during *de*serialization of json well.

consider following class:

public class tax {     public tax() { }      public int id { get; set; }      [required]     [range(1, int.maxvalue)]     [ignoredatamember]     public int propertyid { get; set; } } 

if post/put following json string action method:

{"position":0,"description":"state sales tax","rate":5,"rateispercent":true,"propertyid":1912} 

i following validation error:

{   "message": "the request invalid.",   "modelstate": {     "newtax.propertyid": [       "the field propertyid must between 1 , 2147483647."     ]   } } 

both [range(1, int.maxvalue)] , [required] attributes invalid.

if remove [ignoredatamember] attribute, works fine.

is there different attribute can used tell mvc binding not ignore property during deserialization?

this happens when posting json string. if post name/value string, everthing works fine.

the answer has behavior of json.net. that's model binding using , it's checking ignoredatamember both serialization , deserialization making useless me (since want use serialization).

the jsonignore attribute works same way.

given that, pulled ignore attributes off properties , switched using json.net's conditional serialization methods.

so add above propertyid field:

public bool shouldserializepropertyid() { return false; } 

that allows deserialization come in blocks serialization going out.
