Question : How do I open and read an Excel file in Visual Basic 2010?

I am trying to convert a VB 6.0 application to VB 2010.  I am having trouble with opening and reading/writing to Excel workbooks.  Can I see an example?

        Dim xlApp As New Microsoft.Office.Interop.Excel.Application
        Dim xlBook As Microsoft.Office.Interop.Excel.Workbook
        Dim xlSheet As Microsoft.Office.Interop.Excel.Worksheet
(NOW WHAT???)

Here is another example, surely written in vb.net (the version of .net has no impact)
