我想一个文本框输入南京，然后页面显示的简码为NJ，请问这个功能怎么实现呀

在chang事件里面用replace方法替换一下就行了

其实现的原理就是先将汉字转化成为内码，然后通过内码和拼音的对照来查找。
　　
　　详细的代码如下所示：

微软好像在.net2.0的哪个补丁中加入了汉字拼字互转的类可以用，你找找

下载一个CHSPinYinConv.msi
是微软的
Simplified Chinese Pin-Yin Conversion Library 库中提供了中文转拼音的方法。很好用

最笨的方法:
  所有汉字按照首字母写到一个键值集合(hashTable)里:
       hashTable.add("A","啊阿安昂爱.....")
       hashTable.add("B","吧被比笨.....")
       hashTable.add("C","擦才藏测.....")
       ...........
然后写一个方法接收汉字参数,返回首字母.
嘎嘎
效率估计慢死了.

那要这么复杂,要就是就题而论的话,就是你写下其他城市也可以的
先建立个二唯数组,比如南京 NJ,北京BJ....,不就可以了

这个问题的解决方法：----------------------------------
下载一个CHSPinYinConv.msi
是微软的
Simplified Chinese Pin-Yin Conversion Library 库中提供了中文转拼音的方法。很好用
这种方法特牛

调试易

我想一个文本框输入南京，然后页面显示的简码为NJ，请问这个功能怎么实现呀
