Can we fill data set from data reader
If yes then how?

well,we can,

but DataSet and DataReader are two complete different objects

however a data source should accept both of them

and how.

You wont find any direct methods to fill dataset using datareader.
You can loop through the records and you can manually create rows ,table,columns and set the value of the record to the rows.

in ADO.NET 2 DataTable would have a method,

DataTable.Load(DataReader);

but in ADO.NET 1.1

look into MSDN,in DbDataAdapter class its Fill method has something interesting,
you can derive your own adapter from DbDataAdaptor and use that method.
