求这样一个函数？

[jfy724]

输入字符串（汉字），输出其汉语拼音。

如 string F(string s)
{
...........................
return str;
}
则F(百度)返回一个'baidu'字符串。

[singwhatiwanna]

这个有点难吧，可能有专门的匹配数据库，我猜的。

[wangting0613]

public static string GetChineseSpell(string strText)
{
if (strText == null || strText.Length == 0)
return strText;
System.Text.StringBuilder myStr = new System.Text.StringBuilder();
foreach (char vChar in strText)
{
// 若是字母则直接输出
if ((vChar >= 'a' && vChar <= 'z') || (vChar >= 'A' && vChar <= 'Z'))
myStr.Append(char.ToUpper(vChar));
else if ((int)vChar >= 19968 && (int)vChar <= 40869)
{
// 若字符Unicode编码在编码范围则 查汉字列表进行转换输出
foreach (string strList in strChineseCharList)
{
if (strList.IndexOf(vChar) > 0)
{
myStr.Append(strList[0]);
break;
}
}
}
}
return myStr.ToString();
}// GetChineseSpell

strChineseCharList 这个没有定义啊。

[kay1990]

好像是的啊，那个中文转换成拼音，难度好打的啊！这个必须有对应的词库才行啊！！！
个人理解。。。。。
看楼下的了！！！

[Joop_Song]

这个问题你要有专门的匹配的数据才能显示啊！

先把汉字和发音存进库中，然后根据输入的汉字辨别发音。。。

这个库很大，不知道有没有现成的。。

[jfy724]

2楼，你的函数缺点东西。

[子夜__]

要有词库

public   static   string   convert(string   chrstr)  
{  
byte[]   array   =   new   byte[2];  
string   returnstr= " ";  
int   chrasc=0;  
int   i1   =   0;  
int   i2   =0;  
char[]   nowchar=chrstr.ToCharArray();  
for   (int   j=0;j <nowchar.Length   ;j++)  
{
//增加了对字符长度判断的处理，避免了因为字符串中存在英文、数字而引起的异常
byte[]   btchk   =   System.Text.Encoding.Default.GetBytes(nowchar[j].ToString   ());
if(btchk.Length   ==   1)
{
returnstr+=nowchar[j].ToString();
continue;
}
array   =   btchk;
i1   =   (short)(array[0]   );  
i2   =   (short)(array[1]   );  
chrasc=i1*256+i2-65536;  
if   (chrasc> 0   &&   chrasc <160)  
{  
returnstr+=nowchar[j];  
}  
else  
{  
for   (int   i=(pyvalue.Length   -1);i> =0;i--)  
{  
if   (pyvalue[i] <=chrasc)  
{  
returnstr+=pystr[i];  
break;  
}  
}  
}  
}  
return   returnstr;  
}
