Load the Excel in Dataset and Access the Column collection to get the ColumnName gives the Column header

       foreach (DataColumn dc in output.Tables[0].Columns)
       {
           Console.WriteLine(dc.ColumnName);
       }

Calling GetSchemaTable on the SqlDataReader derived class returns a DataTable with a Columns property. This will give you the names of the columns.
