string.empty converted to null when passing JSON object to MVC Controller

Question

I\'m passing an object from client to server. Properties of the object which are represented as string.empty are being converted to null during this process. I was wondering

Answer 1

When posting data with $.ajax, null is not a possible value for a property of the data option. If you look at the request with an http debugger, you will see that it's converted to an empty string.

So I guess that your MVC controller is applying the opposite conversion.

What I do in an ajax application to workaroung this issue is that I don't use the data option of $.ajax(), but I serialize everything in JSON and put it into a single field "data" of the data option. Like that you don't have problems with null values. Of course, you have to deserialize on the server side.
