[lamyae Benabdeljalil]

I am using mono 1.0, and i have a problem with a lethod of the
System.Convert class. My statement is :
 Hashkey=System.Convert.FromBase64String(dr.GetValue(0).ToString());
i get the following error:
Unhandled Exception: System.IndexOutOfRangeException: Array index is out
of range.
in <0x00098> System.Data.Odbc.OdbcDataReader:GetValue (int)
in <0x00054> (wrapper remoting-invoke-with-check)
System.Data.Odbc.OdbcDataReader:GetValue (int)
in <0x003d6> Test:checkkeys ()
in <0x000cb> Test:Main ()

Please, can you help me?
