How would you use the TJSONXXX classes to parse this JSON:

{
"result":
[
{
"MecYear":"0",
"10YrSurrIndexCurr":"0.00",
"10yrSurrIndexGuar":"0.00",
"20yrSurrIndexCurr":"0.00",
"20yrSurrIndexGuar":"0.00",
"Message":"None",
"Error":""
}
]
}

It's a response from a datasnap request. I tried using a JSON pair with the "result" begin the name part and the array being the value part (only one element in the array) . Then in the array is another JSON Object. But I'm getting confused..

    TJSONXxxx should have a isNull, usInteger, isArray... and so on. No?

    Dany Marmur There is already Null which checks for IsNull. One can still use TryGetValue to check for compatibility with a specific type. That might even be preferred when handling enumeration types which are represented as strings inside JSON. Besides that one can ask for value is TJSONArray and others.
