C#_获取汉字拼音（三个方案）
时间：03-24来源：作者：点击数：
我们在做系统是经常遇到需要通过汉字提取汉字拼音 的情况 ，我在网上搜集了几种获取方案包含了收首字母和完整拼音的获取，供大家参考！
在此向原作者表示感谢！
方案一：这个本人测试通过，最简单
/// <summary>
/// 获取拼音
/// </summary>
/// <param name="str"></param>
/// <returns></returns>
public string GetPYString(string str)
{
string tempStr = "";
foreach (char c in str)
{
if ((int)c >= 33 && (int)c <= 126)
{//字母和符号原样保留
tempStr += c.ToString();
}
else
{//累加拼音声母
tempStr += GetPYChar(c.ToString());
}
}
return tempStr;
}
///
/// 取单个字符的拼音声母
///
/// 要转换的单个汉字
/// 拼音声母
public string GetPYChar(string c)
{
byte[] array = new byte[2];
array = System.Text.Encoding.Default.GetBytes(c);
int i = (short)(array[0] - '\0') * 256 + ((short)(array[1] - '\0'));
if (i < 0xB0A1) return "*";
if (i < 0xB0C5) return "a";
if (i < 0xB2C1) return "b";
if (i < 0xB4EE) return "c";
if (i < 0xB6EA) return "d";
if (i < 0xB7A2) return "e";
if (i < 0xB8C1) return "f";
if (i < 0xB9FE) return "g";
if (i < 0xBBF7) return "h";
if (i < 0xBFA6) return "j";
if (i < 0xC0AC) return "k";
if (i < 0xC2E8) return "l";
if (i < 0xC4C3) return "m";
if (i < 0xC5B6) return "n";
if (i < 0xC5BE) return "o";
if (i < 0xC6DA) return "p";
if (i < 0xC8BB) return "q";
if (i < 0xC8F6) return "r";
if (i < 0xCBFA) return "s";
if (i < 0xCDDA) return "t";
if (i < 0xCEF4) return "w";
if (i < 0xD1B9) return "x";
if (i < 0xD4D1) return "y";
if (i < 0xD7FA) return "z";
return "*";
}
-----------------------------------------------------------------------------------
方案二；
首先要引用Visual Studio International Pack -->CHSPinYinConv.msi 里面的包ChnCharInfo
using Microsoft.International.Converters.PinYinConverter; //引入命名空间
/// <summary>
/// 获得一个字符串的拼音
/// </summary>
/// <param name="str"></param>
/// <returns></returns>
public static string GetPinYin(string str)
{
StringBuilder sb = new StringBuilder();
foreach (char item in str)
{
//判断是不是汉字，如果不是原字符返回
if (ChineseChar.IsValidChar(item))
{
sb.Append(GetPinYin(item));
}
else
{
sb.Append(item);
}
}
return sb.ToString();
}
/// <summary>
/// 获得单个字符的拼音
/// </summary>
/// <param name="c"></param>
/// <returns></returns>
public static string GetPinYin(char c)
{
ChineseChar cc = new ChineseChar(c);
string str = cc.Pinyins[0]; //多音字只取第一个
return str.Substring(0, str.Length - 1); //去掉最后的声调
}
----------------------------------------------------------------------------------------------------------------------------------------------------------------------
