Custom Pipeline Component -how to loop through Ibasemessage.bodypart

I wrote a custom pipeline component to validate csv data before inserting into Sql server DB.

my problem is I have to be able to read the following data and retreive each field data to check if  required fields are empty or not and then let the orchestration process the data.

my Ibasemessage.bodypart looks like foll:

I am unable to understand this format and how do I retreive my field names from this stream of data :
eg: I have to check if  (Deal# = “” & VIN =””) then
    “DO NOT PROCESS THE ROW”
    “GO TO NEXT ROW “
    “AND INSERT ONLY THOSE ROWS THAT HAVE rREQUIRED FIELDS”
    “I HAVE 73 fields in each ROW.
    “1st row is header row (I need to exclude that row too)

HOW DO I DO THIS , Please any support is gr8tly appreciated
