import excel file into dropdownlist then export to sql server 2005

i am handling a project where user can choose the excel file and the field in the excel file to export into sql server 2005. which mean there will be dropdownlist where the user can choose the field and so on. anyone know how to do this?I'm a bit uncertain how this question is Asp.Net related. Please clarify how it is.|||which mean i will need to import the excel file into a dataset and then bind the dataset to the drop down list and at last import it to the sql server 2005. it can be in vb.net or asp.net
