interface don´t expose some fields

[Luiz]

I'm constructing a class to database access using the
following interface component :

IDBDataAdapter my_i_DataAdapte r;
......
The project has an instance of the class
OdbcDataAdapter my_odbcDA, then I make this:

my_i_DataAdapte r = my_odbcDA;

but when I try to set the parameters, the
interface don't expose the field "value",
So I can not do this:

this.my_i_DataA dapter.SelectCo mmand.Parameter s[0].value = variable ;

How can I resolve this ?
thanks.

Luiz,
See the IDbCommand and IDbDataParamete r interfaces, which cover your
SelectCommand and its parameter(s) respectively.

RE: interface don´t expose some fields

Hi Peter,

thanks for your reply, but the solution was not to consult the documentation
of
the IDBCommand, IDbDataParamete r or IDataAdapter but to use the class
DBAdapter ( without I ) that is a better implementation of the Interface
IDataAdapater. That class is locate in System.Data.Com mon and expose more
methods and properties. Other classes also has implementation in details like
DBCommand, DBParameter...
