这是我在这里的第一个留言，而且我不是母语为英语的人，所以请提前感谢你不要轻视我的错误。
我的问题是我想要更改OpenFileDialog和SaveFileDialog的默认文本，因为在我的应用程序中有一个更改语言设置的选项。
按钮文本是＆＃34; Save＆＃34;和＆＃34;打开＆＃34;。
我可以通过MessageBoxManager为其他按钮执行此操作，但是我也需要为按钮执行此操作＆＃34; Save＆＃34;按钮＆＃34;打开＆＃34;。
这些按钮必须通过其他方式处理，因为我无法找到他们的＆＃34; ID＆＃34; （ID_ok = 1，ID_cancel = 2），我无法找到＆＃34;保存＆＃34;。
所以，如果您对解决方案有任何想法，我将非常感激。

编辑： 首先，感谢纠正我的错误（其中很多）^^ ....原因，我想翻译按钮很简单。我的程序必须翻译成5种语言，可以通过菜单选择。我没有＆＃34;窗口终极＆＃34;改变我想要的设置语言。
但无论如何，我不希望每次点击都改变操作系统的语言。我只有两个解决方案由我自己创建所有的messageBox和openDialog并更改程序调用messageBox.show由我的新表单（将花费很多时间......）或正确翻译按钮的开关/保存对话框的1500倍。所使用的计算机适用于该程序，不应使用任何其他程序。
目前我能够正确翻译所有的邮箱，但我的问题是按钮＆＃34;保存＆＃34;，＆＃34;打开＆＃34;（此文字更改为我的按钮＆＃34 ;好的＆＃34;）如果你想我可以告诉你在哪里可以下载项目以更好地了解实现的功能
