class AppendSample
{
  static void Main()
  {
    string constr = "User Id=scott;Password=tiger;Data Source=oracle";
    OracleConnection con = new OracleConnection(constr);
    con.Open();
 
    OracleBlob blob = new OracleBlob(con);
      
    // Append 2 bytes {4, 5} to the OracleBlob
    byte[] buffer = new byte[3] {4, 5, 6};
    blob.Append(buffer, 0, 2);
 
    byte[] appendBuffer = blob.Value;
 
    // Prints "appendBuffer = 45"
    Console.Write("appendBuffer = ");
    for(int index = 0; index < appendBuffer.Length; index++)
    {
      Console.Write(appendBuffer[index]);
    }
    Console.WriteLine();
