如何使公共 MySQLDataReader 符合 CLS？

Question

我有一个符合 CLS 的项目，除了一个变量声明让我很困惑如何更正。

我有一个类叫 MySQL，总结起来是这样的：

public class mysql
 implements idisposable

 private connection as new mysqlconnection
 private command as new mysqlcommand
 <CLSCompliant(false)> public reader as mysqldatareader

 public sub new(byval query as string)
  if connection.state = connectionstate.open then
    connection.connectionstring = my.settings.connectionstring
    connection.open()

    command.connection = connection
    command.commandtext = query
 end sub

 public sub parameters(byval name as string, byval value as string)
  command.parameters.addwithvalue(name, value)
 end sub

 public sub retrieve()
  reader = command.executereader()
 end sub

 public sub send()
  command.executenonquery()
 end sub

 public sub close()
  if me.command.connection.state = connectionstate.open then me.command.connection.close
  if me.connection.state = connectionstate.open then me.connection.close
  me.dispose()
 end sub

 #region "IDisposable support"
  private disposedvalue as boolean
   protected overridable sub dispose(disposing as boolean)
     if not me.disposedbalue then
       if disposing then
       #dispose maaged state
       end if

       connection.dispose()
       command.dispose()
       reader = nothing
      end if
      me.disposedvalue = true
   end sub

  public sub dispose() implement idisposable.dispose
    dispose(true)
    gc.suppressfinalize(me)
  end sub
 #end region

end class

用法：

dim sql as new MySQL("SELECT * FROM TABLE WHERE NAME = ?Name")
sql.parameters("?Name", me.textboxusername.text)

call sql.retrieve()

while sql.reader.read
  text = sql.reader.getstring(sql.readergetordinal("User_Name")
end while

call sql.close()

作为 MySQLDataReader 的公共阅读器不符合 CLS，我不确定如何更正该问题。我已升级到最新的 mysql 数据连接器版本。我想知道是否应该将其设为私有变量并读取结果抛出一个函数？

对于以下代码 sn-p 中的大写错误、拼写错误等，我深表歉意，我是在从远程桌面连接查看时输入的。

先生，试试这个代码来声明mysqlcommand。

    Public query As String, cmd As MySqlCommand, reader As MySqlDataReader
    Public SQLConnection As MySqlConnection = New MySqlConnection
