C#中汉字转换数字和汉字转换拼音的的方法

1、汉字数字相互转换
 
view plainprint?
public static string ChineseTONumber(string chineseStr)
{
            string numStr = "0123456789";
            string chineseStr = "零一二三四五六七八九";
            char[] c = chineseStr.ToCharArray();
            for (int i = 0; i < c.Length; i++)
            {
                int index = chineseStr.IndexOf(c[i]);
                if (index != -1)
                    c[i] = numStr.ToCharArray()[index];
            }
            numStr = null;
            chineseStr = null;
            return new string(c);
 }
public static string NumberToChinese(string numberStr)
{
            string numStr = "0123456789";
            string chineseStr = "零一二三四五六七八九";
            char[] c = numberStr.ToCharArray();
            for (int i = 0; i < c.Length; i++)
            {
                int index = numStr.IndexOf(c[i]);
                if (index != -1)
                    c[i] = chineseStr.ToCharArray()[index];
            }
            numStr = null;
            chineseStr = null;
            return new string(c);
}
2、汉字转换拼音
当然这种方式解决不了多音字的问题，所以只能在一般的场合使用。
