website with excel database prepared in asp.net and c#

Do you really have to use an Excel spreadsheet as a database? That's a very very very bad idea... Better take Microsoft SQL Server.
And: Excel has some "compatibility" issues with ASP.

Given below is a working code

C#

If fileExtension = ".xls" Then
     ExcelConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & fileName & ";Extended Properties='Excel 8.0;HDR=YES;'"
 Else
     ExcelConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & fileName & ";Extended Properties='Excel 12.0 Xml;HDR=YES;'"
 End If


 Dim dtFill As New DataTable

Make use of OLEDB connection.

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\MyExcel.xls;Extended Properties="Excel 8.0;HDR=Yes;IMEX=1";

or plz check the belwo code

public static DataTable ReadExcel(string path)
{
    //create a DataTable to hold the query results
    DataTable dTable = new DataTable();

    try
    {
        if (!File.Exists(path))
            return null;

        //create the "database" connection string 
        string connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;";

        //create the database query
        string query = "SELECT * FROM [Sheet1$]" ;

        //create an OleDbDataAdapter to execute the query
        OleDbDataAdapter dAdapter = new OleDbDataAdapter(query, connString);
        //fill the DataTable
        dAdapter.Fill(dTable);
        dAdapter.Dispose();
    }
    catch (Exception e)
    {
        Console.WriteLine(e);
    }

    return dTable;
}
