I have read about desearlizing a json file into class fields which I understand. But what I cannot find in a tutorial is how to read in the json data. Everyone just adds the data to a variable and uses it. I will be passing in a json file from a mobile app. I know I should use a web service but for now I want to use an asp.net ASPX page to do this. I will be using the newton king json control.

Can someone show me how to read in the json to a variable? Hopefully I will be set then!
