One more thing worth noting.

If you are using oracle client, and would like to include unicode characters in the CommandText, you should add the folloing line to the start of your application:

System.Environment.SetEnvironmentVariable("ORA_NCHAR_LITERAL_REPLACE", "TRUE");

This will allow you, in case you need it, to use the following syntax:

command.CommandText = "INSERT into UNICODEDATA (ID, UNICODESTRING) Values (11, N'Τι κάνεις;')";
