How to handle user defined exception from C#?

Question

Hi:
I have some PL/SQL code that will throw a user defined exception if certain conditions are met. How do I handle user defined exceptions if this procedure/function is being called from C#? C# can handle a normal Oracle SQL error (e.g. ORA-XXXX) because they are defined in the proper class, but how do I get it to know about my user defined exception? Does anyone have any links to examples of doing this?
Thanks.

Hi Gaff,
Is there a particular problem you're having doing this? It works as normal for me...
Cheers

PLSQL
=========
create or replace procedure throwsomething as
begin
raise_application_error(-20001,'kaboom');
end;
ODP
=====
    class Program
        static void Main(string[] args)
            using (OracleConnection con = new OracleConnection())
                con.ConnectionString = "user id=scott;password=tiger;data source=orcl";
                con.Open();
                using (OracleCommand cmd = new OracleCommand())
                    cmd.CommandText = "begin throwsomething;end;";
                    cmd.Connection = con;
                    try
                        cmd.ExecuteNonQuery();
                    catch (OracleException oe)
                        Console.WriteLine("caught " + oe.Message);
OUTPUT
========
caught ORA-20001: kaboom
ORA-06512: at "SCOTT.THROWSOMETHING", line 3
ORA-06512: at line 1
