Configuration :: Read The System.web.extensions/scripting/webServices/jsonSerialization Value?

I'm trying to read the value in the web.config file for the <jsonSerialization /> element. Here's an example showing where it appears:

<configuration> <system.web.extensions> <scripting> <webServices> <jsonSerialization maxJsonLength="500000"/> </webServices> </scripting> </system.web.extensions></configuration>

So, here's what I did to try and get the value:

[Code]....

But it turns out that the OpenWebConfiguration(null) method call is returning the global web.config file, whereas I want the web.config file for this particular site. If I hard-code in the path to this particular site, then it works--but then my code isn't portable. There must be a way to open the web.config file for the particular site that the code is hosted on--isn't there? Could somebody point me in the right direction?nd, if there's another way I should go about trying to get the maxJsonLength attribute out of the web.config, let me know. I can't just instantiate a JavaScriptSerializer object and inspect the MaxJsonLength property, I already thought of that :-)
