JSON serialization error [maxJsonLength property.]

In my previous project I need to retrieve ticket  from Web service.When I request the web service it return a ticket as JSON format.Some time I need to retrieve more than 10 lacks ticket per requet.In that time I got the following error

Exception information: Exception type: InvalidOperationException Exception message: Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

Solution is 

            We need to set Maximum allowed length of json response in Web.config file 

The MaxJsonLength property cannot be unlimited, is an integer property that defaults to 102400 (100k).

You can set the MaxJsonLength property on your web.config

<configuration>    <system.web.extensions>        <scripting>            <webServices>                <jsonSerialization maxJsonLength="50000000"/>            </webServices>        </scripting>    </system.web.extensions> </configuration>
