How to handle a missing dictionary element?

Sometimes the JSON returned doesn't contain the wind/deg element so thought I could try and catch this like this:

try
{
windd = degtocompass(data["wind"]["deg"]);
}
catch( ex )
{
windd = "?";
}

But I still get Failed invoking <symbol> Unexpected Type Error. Is there a good way to see if that element actually exists?

Seems to work! ;-)

if (data["wind"]["deg"] == null)
{
windd = "?";
}
else
{
windd = degtocompass(data["wind"]["deg"]);
}
