I’m trying to deserialize a JSON object in c#, my problem is that one

  • 0

I’m trying to deserialize a JSON object in c#, my problem is that one of the fields can contain html text (I plan on sanitizing it afterwards).

I’m using a JavaScriptSerializer object to deserialize, but I’m getting a “Invalid object passed in“ error (from the JavaScriptSerializer). If I pass plain text for that same field it works fine and the other fields (including a date and an array) in the object also deserialize correctly so it seems like the html is what’s tripping it up.

I’m using JSON.stringify to serialize the Javascript object and I’m passing it to my page via jQuery.

Is there something I’m supposed to do to in order to pass a string that contains html? I’ve tried enclosing it in quotes, but it didn’t help.

As an example of a string that’s accepted vs what throws an error: “Test” is fine while

"<div style="text-align: center;">Test</div>" is not.
Strangely <span> tags also seem to be fine.

    Can you encode the html with the javascript escape() function before serializing.
