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！

                foreach (char c in str)
                {
                    if ((int)c >= 33 && (int)c <= 126)
                    {//字母和符号原样保留   
                        tempStr += c.ToString();

            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>

            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
