ODP.NET

I have something similar to the information below:

OracleCommand oraCmd = new OracleCommand("insert into my_table (field1, field2) values (:Param1, :Param2)", new OracleConnection(ConfigurationManager.ConnectionStrings["fsgebs"].ConnectionString));
oraCmd.Parameters.Add("Param1", ### I want to use a ControlParameter from the web form here ###);
oraCmd.Parameters.Add("Param2", ### I want to use a ControlParameter from the web form here ###);

I have a web form with about 20 fields and I don't really want to manually do all of this. ControlParameter would be ideal.

Can anyone explain how I can do this? Will I need casting? Obviously I'm using C# here, but if someone has a VB example that might help.

I have tried each of the three lines below with no luck.
OracleParameter p = (Parameter)(new ControlParameter("Field1", "wizCreateRequest$txtItemNumber"));
OracleParameter p = (OracleParameter)(new ControlParameter("Field1", "wizCreateRequest$txtItemNumber"));
OracleParameter p = new ControlParameter("Field1", "wizCreateRequest$txtItemNumber");

Thanks!
