C# 汉字转化拼音的简单实例代码

首先引入ChnCharInfo.dll 第3方的一个库

代码：

btn_chinChar_Click事件：

扩展方法：

            if (string.IsNullOrEmpty(value))return null;

            start = 0;
            list = new List<string>();

            for (i = 0; i < value.Length; ++i)
            {
                c = value[i];
                if (ChineseChar.IsValidChar(c))
                {
                    if (i > start)
                    {
                        list.Add(value.Substring(start, i - start));
                    }
                    chinChar = new ChineseChar(c);
                    list.Add(chinChar.Pinyins.First().Substring(0, chinChar.Pinyins.First().Length - 1).ToLower());
                    start = i + 1;
                }
            }

            if (i > start)
            {
                list.Add(value.Substring(start, i - start));
            }
            return list;
        }
    }
</div>
运用结果：
