I use System.Data.OracleClient to connect and operate oracle database;
But I find a problem when inserting into oracle database with chinese
character;
Here is a simple exapmle:

using System;
using System.Data;
using System.Data.OracleClient;

namespace Test{
    class MainEntry{
        public static void Main(string[] args){
            String connString = "server=video;User Id=mono;password=jcyjcy";
            String insertSql = "INSERT INTO test(name) values (:name)";
            OracleConnection conn = new OracleConnection(connString);
            try{
                conn.Open();
                OracleCommand command = new OracleCommand();
                command.Connection = conn;
                command.CommandText = insertSql;
                command.CommandType = CommandType.Text;
                OracleParameter parm = new OracleParameter(":name",
OracleType.VarChar);
                // insert a Chinese stiing into oracle database(the string's
length is 4)
                parm.Value = "²âÊÔ²åÈë";
                command.Parameters.Add(parm);
                command.ExecuteNonQuery();
            }
            catch(Exception ex){
                Console.WriteLine(String.Format("Error is: {0}",ex.Message
));
            }
            finally{
                conn.Close();
            }
        }
    }
}


and the create table is :
create table test(name varchar(1000));

in sqlplus :
select * from test;
You will see the result is not we expected,not all the character insert into
the database.

Can't anybody tell me how to resolve this problem?
