Import Excel Data Using Generic Sheet Name

Hello,
I'm importing data from an excel spreadsheet into an ASP.NET web page.  The problem is the sheet name keeps changing.  It's always the first sheet in the excel book - but the users change the name.

Is there a generic name for the first sheet in Excel.   So if the user names the sheet to "employees" - when I make a connection can I use something like [Sheet(0)]?

Using ASP.NET 4.0 and xlsx file.

Here's my typical connection:  (Source name not complete path here.)
In Web.config
 <add name="csXLMembers" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=...\Members.xlsx;Extended Properties=Excel 12.0"/>

Code Behind aspx Page
 Dim conString As String = ConfigurationManager.ConnectionStrings("csXLMembers").ConnectionString

****  The following line is where I want to use a generic name instead of Sheet1$
 Dim cmd As OleDbCommand = New OleDbCommand("SELECT * FROM [Sheet1$]", con)
