It is possible to refer to the illustrations in the subsequent documentation. Personally, all of it does my head in and my head only has the potential to explode 3 periods per day:
注意:加密文件之后如果忘记了用来加密该文件的密码,再想恢复出原始文件就不可能了。当然,这与密码本身的复杂程度有关,要想保证文件的安全,最好采用较复杂的密码,例如混合运用字母、数字和特殊字符(如“$”符号等)。
然而必须说明的是,没有一种防范泄密的安全技术是绝对坚固的,因为密码有可能被未经授权的人获得。
Like many of the finer items in life, File Explorer has gotten far better with age. To check it out in Windows 10, choose its icon within the taskbar or the Start menu, or push the Home windows emblem crucial + E with your keyboard.
The More choice is now not offered. So as to add or eliminate information to the type by menu, you will need to briefly change to "'Aspects" casper77 see, incorporate the main points you'd like like below, and afterwards swap back towards the layout see you need.
类型系统提供重要的广度,在某种程度上同样迎合了安全性、描述性、动态性和本机互操作性。 首先,类型系统启用面向对象的编程模型。 它包括类型、(单基类)继承、接口(包括默认方法实现)和虚拟方法调度,为对象方向允许的所有类型分层提供合理的行为。 泛型类型 无处不在,使你能够将类专用于一个或多个类型。

While you key in the Research Box, Windows Lookup will instantly casper77 commence a straightforward research in the index by default to match your typed casper77 textual content with folder names, documents names, the contents of information, and file Homes. It's going to then Exhibit the search engine results in File Explorer.
注意这段代码创建了三个文件流:fin,表示明文形式的原始文件;fout,加密结果文件;crStream,加密流,用来把DES加密的结果转入输出文件fout。增加一个crStream流的好处是不必把结果保存到临时文件或缓冲区。
Doesn't work ! Observe, I had no interval during the research string and do NOT want just one inside the resultant listing of filenames !
C# 面向对象,运行时支持对象方向。 C# 需要垃圾回收,运行时提供跟踪垃圾回收器。 库(以及应用堆栈)将这些功能塑造成概念和对象模型,使开发人员能够在直观的工作流中高效编写算法。

而这种原始转换(由子类转换为父类)方向相同的可变性,被称为协变(covariant);其反向操作则被称为逆变(contravariant)。当同样的情形应用于泛型时,例如:
