windows mobile常用数据库对象应用

string dest = "mytest.sdf";             SqlCeConnection cnn = new SqlCeConnection("Data Source =" + dest);  try {                 cnn.Open();                    SqlCeCommand cmd = cnn.CreateCommand();                  cmd.CommandText = "select name from test";                 SqlCeDataReader rdr = cmd.ExecuteReader();                  while (rdr.Read()) {                     this.label1.Text = rdr["name"].ToString();                 }                                                rdr.Close();                 cmd.Dispose();                 cnn.Close();                 MessageBox.Show("Ok"); }               catch (SqlCeException err)  {                 MessageBox.Show(err.ToString()); }             finally {                cnn.Dispose();            }   注：数据库在测试程序目录中，数据库对象SqlCeConnection,SqlCeCommand,SqlCeDataReader比较常用到的对象，在测试用发现Sql Server Compact Edition 3.5不支持top关键字，很是苦恼。
