漢字轉化為拼音

很多問題都是因為中文問題造成的

如檔案名最好别用中文

現在的解決方法一般是産生一個ID,将這個ID做檔案名

網頁上如果url帶漢字也經常出錯

現在的解決方法一般用urlencode編碼

現在用了這個轉化，就好多了

原理：利用哈希表技術   Hashtable ht=new Hashtable(10);

1.添加索引，如： ht.put("-20295","ang");

2.倒序周遊，如：  while(!ht.containsKey(Integer.toString(num)))num--;

<%@ page language="java" import="java.util.*" contentType="text/html" %>

<%!

Hashtable ht=new Hashtable(10);

String g(Integer n){

 int num=n.intValue();

 if(num>0&&num<160){

  return String.valueOf((char)num);

 }

 else if(num<-20319||num>-10247){

  return "";

 }

 else{

  if(ht.size()==0){b();}

  while(!ht.containsKey(Integer.toString(num)))num--;

  return ht.get(Integer.toString(num)).toString();

 }

}

String c(String str){

 char[] hz=str.toCharArray();

 int len=str.length();

 int p,q;

 String ret="";

 for(int i=0;i<len;i++){

  p=(int)hz[i];

  if(p>160){

   q=(int)hz[++i];

   p=p*256+q-65536;

  }

  ret+=g(new Integer(p));

 }

 return ret;

}

用C#實作漢字轉化為拼音

其實作的原理就是先将漢字轉化成為内碼，然後通過内碼和拼音的對照來查找。

詳細的代碼如下所示：
