将汉字转为英文字母 整理笔记

将汉字转为英文字母来记录数据，在此跟大家分享一下了。。。

       //调用 ConvertLetters（String chinese）方法，传入参数（只要是汉字，则转为大写的英文字母，可自己去定义了）

        public String ConvertLetters(String chineseStr)
        {
            try
            {
                char[] buffer = new char[chinese.Length];
                for (int i = 0; i < chinese.Length; i++)
                {
                    buffer[i] = ConvertChar(chinese[i]);
                }
                return new String(buffer).Replace(" ", "");
            }
            catch
            {
                return "";
            }
        }
        
        public char ConvertChar(Char chinese)
        {
            try
            {
                Encoding gb2312 = Encoding.GetEncoding("GB2312");
                Encoding unicode = Encoding.Unicode;
                byte[] unicodeBytes = unicode.GetBytes(new Char[] { chinese });
                byte[] asciiBytes = Encoding.Convert(unicode, gb2312, unicodeBytes);
                if (asciiBytes.Length < 2)
                    return chinese; //待转换的字符在ascii码表示范围内
                int n = (int)asciiBytes[0] << 8;
                n += (int)asciiBytes[1];
                //   根据汉字区域码获取拼音声母
