C#大学课程(第五版)课后习题16.5儿童黑话

/*16.5
(儿童黑话)编写一个将英语短语编码成pig Latin( 儿童黑话) 的程序。pig Latin 是一种常用于娱乐的编码语言形式。有许多种用于构成Pig Latin 短语的方法，出于简单性的考虑，这里使用如下的一种算法。
为了将每一个英语单词翻译成一个pig Latin 单词，将英语单词的第一个字母放在pigLatin单词的未尾,并在其后添加字母“ay”。这样，单词“jump”就变成了“umpjay" ;单词"the”变成"hetay" 。单词间的空格保持不变。假设有下列条件: 英语短语由用空格分隔的单词组成，没有标点符号且所有的单词都有两个或多个字母。让用户输人一个句子。利用本章中讨论过的的技术将这个句子拆分成单词。用GetPigLain 方法将每个单词翻译成pie Latin 单词。一个文本框中持续显示所有转换后的句子。
