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：

private void btn_chinchar_click(object sender, eventargs e)
        {
            chinesechar cr =null;
            string str = "", txtstring = txt_string.text.trim();
            if (!string.isnullorempty(txtstring))
            {
                foreach (var item in cr.getchinesespellings(txtstring))
                {
                    str += item + "-";
                }
            }
            messagebox.show(str);
        }

扩展方法：

public static class chinesecharacters
    {
        public static icollection<string> getchinesespellings(this chinesechar chinchar ,string value)
        {
            list<string> list;
            int i,start;
            char c;

            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;
        }
    }

运用结果：
