How to extract GXDLMSProfileGeneric's buffer data

My Meter Is ACE SL7000 - Itron
I'm writing the steps I follow

1. Init GXDLMSProfileGeneric's
GXDLMSProfileGeneric obj = new GXDLMSProfileGeneric("1.1.89.1.1.255");

2. Read Data
var captureObjects = conn.Comm.Read(obj, 3);//CaptureObjects: 3
Log(captureObjects);
//Not Reading Buffer without read CaptureObjects
Log("Buffer");
var buffer = conn.Comm.Read(obj, 2);//Buffer: 2
Log("Buffer SerializeObject");
Log(buffer);

Here is the result CapturedObjects and Buffer

You Can Visualise Following data from http://chris.photobooks.com/json/

1. CapturedObjects http://www.buurl.com/guruxqcap
2. Buffer http://www.buurl.com/guruxqbuff

According to the this data
a) How to extract Buffer or seek data properly way. Or should I match Buffer and CaptureObjects
b) What is the CaptureObjects's (List<GXKeyValuePair<GXDLMSObject, GXDLMSCaptureObject>>) GXDLMSCaptureObject:Value data and How should i use
c) What does it do CaptureObjects and How should i use
d) Is there relationship beetween CaptureObjects and Buffer, What is it?
e) How to detect date types from Buffer

Thanks for advice.
