JSON serialized data exceeds maximum value (maxjsonlength)

1. Serialization:

The following code will error when the object is too large: There was an error serializing or deserializing. The length of the string exceeds the value set for the Maxjsonlength property.

1. Jsonobj when the big time will be error
2. var serializer = new JavaScriptSerializer ();
3. Return serializer. Serialize (Jsonobj);

Using Newtonsoft.json also has this problem, the solution is to set Maxjsonlength:

1. var serializer = new JavaScriptSerializer ();
2. Serializer. Maxjsonlength = Int32.MaxValue; //Set to the maximum value of int
3. Return serializer. Serialize (Jsonobj);

2. Ajax Access WebService:

With jquery access to WebService, if the post data is too large, you will also receive a HTTP500 error, and the workaround is to set the maxjsonlength in Web. config:

2. <system.web.extensions>
4. <scripting>
6. <webservices>
8. <!--units in bytes--
10. <jsonserializationmaxjsonlength="1024000"/>
12. </webservices>
14. </Scripting>
16. </system.web.extensions>
