其中有这么一条语句 Console.WriteLine("{0,-9}{1,-6}{2,-18}{3}",m_record.name, m_record.age,m_record.phone,m_record.address); 它表示对输出进行格式化{} 中使用的第二个数表示输出占据的屏幕位数正 数表示从右边起计而负数表示从左边起计。作者:Q_Lucky

揭开神秘面纱：什么是红客联盟？,红客和黑客白客灰客（骇客）有什么区别？
作者:Q_Lucky
本文转载自18580.com
概念：
“红客”词源来源于黑客，在中国，红色有着特定的价值含义，正义、道德、进步、强大等等。红客是一种精神，它是一种热爱祖国、坚持正义、开拓进取的精神。所以只要具备这种精神并热爱着计算机技术的都可称为红客。红客通常会利用自己掌握的技术去维护国内
网络的安全，并对外来的进攻进行还击。
定义：
红客红客是指维护国家利益，不去利用网络技术入侵自己国家电脑，而是维护正义，为自己国家争光的黑客。
红客与其它客的联系和区别：
黑客，现在已被分为，红客、白客、灰客。
红客则是一些技术过硬但又不屑与那些破坏者为伍的人，称做红客。
白客，又称安全防护者，用寻常话说就是一些原本的黑客转正了，他们进入各大科技公司专门防护网络安全。
灰客，亦骇客，又称破坏者，他们在那些红、白、黑客眼里是破坏者，是蓄意毁坏系统，恶意攻击等等一系列的破坏手段。
黑客即建设，骇客则破坏。
