基于C#+winform开发的“回文判定”程序：对于一个从键盘输入的字符串，判断其是否为回文。回文即正反序相同。如“abba”是回文，而“abab”不是回文。此判定程序包含了三种判定方法：1、根据数组元素；2、利用栈先进后出，队列先进先出的特点3、分段检测。（已给出完整的代码注释）-Based on C#+ winform development "palindromes judgement" program: for a keyboard input from the string, decide whether it is reported. That same palindromes positive and negative sequence. Such as "abba" is reported, and "abab" is not reported. The judge program includes three convicted methods: 1, according to an array element　2, the use of advanced after a stack, queue advanced first out features 3, stage detection.
