private void getContain(string pgid)
{
int nBufferSize = 255;
byte[] arrbyte = new byte[nBufferSize];
MemoryStream objMemoryStream;
BinaryFormatter objBinaryFormatter;
SqlCommand comm = new SqlCommand();
comm.Connection = new SqlConnection(ConfigurationSettings.AppSettings["connectionstring"]);
comm.CommandText =
comm.Parameters.Add(new SqlParameter("@pgid", SqlDbType.Char,14));
comm.Parameters["@pgid"].Value = pgid;
comm.Connection.Open();
SqlDataReader dr = comm.ExecuteReader();
if (dr.Read())
{
titletxt.Value = dr["title"].ToString();
arrbyte = (byte[])dr["contect"];
objMemoryStream = new MemoryStream(arrbyte);
objBinaryFormatter = new BinaryFormatter();
cotain.Text = (string)objBinaryFormatter.Deserialize(objMemoryStream);
objMemoryStream.Close();
}
comm.Connection.Close();
}


中间这两行中
titletxt.Value = dr["title"].ToString();
arrbyte = (byte[])dr["contect"];
titletxt是什么意思啊,contect又是什么意思
