jquery - How to increase the json size limit for ASP.NET WebAPI Post call? -

my form on page little large. collects monthly measurement data. please take @ sample:

{ "year":2013, "month":3, "records":[     {"id":0,"date":"3/1/2013","riversection":5,"usernumber":56},     {"id":0,"date":"3/1/2013","riversection":7,"usernumber":200},     {"id":0,"date":"3/1/2013","riversection":8,"usernumber":556},     {"id":0,"date":"3/2/2013","riversection":5,"usernumber":56},     {"id":0,"date":"3/2/2013","riversection":7,"usernumber":200},     ...     ...     {"id":0,"date":"3/31/2013","riversection":7,"usernumber":200} } 

so posting big data apicontroller.

i works fine in local machine using visual studio debugger server. after uploaded code server (iis 6). gives 500 internal server error.

i tried posting sample data , checked length of stringified json.

in 1 sample data set, length of json 5743, , got "success". if json size goes 17345, got 500 internal server error.

so tried increase limit of json. base on this post

in web.config:

<system.web.extensions> <scripting>   <webservices>     <jsonserialization maxjsonlength="5000000">     </jsonserialization>   </webservices> </scripting> </system.web.extensions> 

but not working.

there answer, using:

var serializer = new javascriptserializer(); serializer.maxjsonlength = int32.maxvalue; 

but should place code? in global.asax?

please note using iis 6. problem? how can correctly increase limit of json size data can hit webapi action?

thank assistance.

try adding aspnet:maxjsondeserializermembers under appsettings in web.config

<add key="aspnet:maxjsondeserializermembers" value="20000"/> 

source: an asp.net request has lots of form keys, files, or json payload members fails exception
