Hi,
Are you getting an error? If so, what?
This works for me..

create table longtab(col1 varchar2(10), col2 long );
using System;
using System.Data;
using Oracle.DataAccess.Client;
using Oracle.DataAccess.Types;
using System.Text;
public class longwrite
public static void Main()
// make a long string
StringBuilder sb = new StringBuilder();
for (int i=0;i<55000;i++)
sb.Append("a");
sb.Append("Z");
string indata = sb.ToString();
Console.WriteLine("string length is {0}",indata .Length);
// insert into database
OracleConnection con = new OracleConnection("user id=scott;password=tiger;data source=orcl");
con.Open();
OracleCommand cmd = new OracleCommand();
cmd.CommandText = "insert into longtab values(1,:longparam)";
cmd.Connection = con;
OracleParameter longparam = new OracleParameter("longparam",OracleDbType.Long,indata .Length);
longparam.Direction = ParameterDirection.Input;
longparam.Value = indata ;
cmd.Parameters.Add(longparam);
cmd.ExecuteNonQuery();
Console.WriteLine("insert complete");
//now retrieve it
cmd.CommandText = "select rowid,col2 from longtab where col1 = 1";
OracleDataReader reader = cmd.ExecuteReader();
reader.Read();
string outdata = (string)reader.GetOracleString(1);
Console.WriteLine("string length is {0}",outdata.Length);
//Console.WriteLine("string is {0}",outdata);
reader.Close();     
con.Close();
con.Close();
}
