Is it possible to get sqldatasource and determine the type of specific column and its header ?

Suppose I have a sqldatasource of this structure
id , Country, Sales, Country Code
Respective types are
Int, String, Double, LongInt
Is it possible to have a code to put into
Label1 their type separated by commas, ie  "Int, String, Double, Int32" and
Label2 their column headers, separated by commas, ie "id , Country, Sales, Country Code"

Thanks
