名称“UpDataDBData”在类或命名空间“Example_1_1.UpdateData”中不存在

  private void UpdataDBData(String myID,String myName)
  {
   //设置访问数据库的连接
   string accessString= ACCESSCONNECTIONSTRING +Server.MapPath("dbfiles//MyFirstAccessDB.mdb").ToString();
   //设置更新数据库的SQL语句
   string cmdText = "UPDATE MyDataTable SET MyName="+myName+"WHERE MyID=" +myID;
   //创建访问数据库的连接＆Command
   OleDbConnection accessConn = new OleDbConnection(accessString);
   OleDbCommand accessComm = new OleDbCommand(cmdText,accessConn);
   try
   {
    accessConn.Open();
    accessComm.ExecuteNonQuery();
    accessConn.Close();
   }
   catch(Exception ex)
   {
    Response.Write(ex.Message);
   }
  }
  private void UpdateDataBtn_Click(object sender, System.EventArgs e)
  {
   if(MyID.Text.Trim().Length>0 && MyName.Text.Trim().Length>0)
   {
    UpDataDBData(MyID.Text.Trim(),MyName.Text.Trim());
    ShowDBData();
   }
  }
  经过检查发现命名空间的引用集已经引用完毕，困扰了半个小时后，终于发现了函数UpDataDBData(MyID.Text.Trim(),MyName.Text.Trim());
调用时upDataDBData应该是updataDBData，完全是大小写错误！
