根据出生日期，计算年龄（距当前时间），调用：Age(20121202); 方法如下：

     private void Age(string Date)
        {
            string RValue = string.Empty;

string NowDate = DateTime.Now.ToString("yyyyMMdd");
DateTime BrithDate = DateTime.Parse(Date.Insert(6, "-").Insert(4, "-"));

            if (DateTime.Now.Year == BrithDate.Year) //年份相等
            {
                #region
                if (DateTime.Now.Month == BrithDate.Month) //月份相等
                {
                    RValue = (DateTime.Now.Day - BrithDate.Day).ToString() + "天";
                }
                else //月份不相等
                {
                    if (DateTime.Now.Day >= BrithDate.Day)
                    {
                        RValue = (DateTime.Now.Month - BrithDate.Month).ToString() + "月";

                    }
                    else
                    {
                        RValue = (DateTime.Now.Month - BrithDate.Month - 1).ToString() + "月";
                    }

}
#endregion

            }
            else //年份不相等
            {
                #region

                if (DateTime.Now.Month > BrithDate.Month)
                {
                    if (DateTime.Now.Day >= BrithDate.Day)
                          RValue = (DateTime.Now.Year - BrithDate.Year).ToString() + "年"+(DateTime.Now.Month-BrithDate.Month).ToString()+"月";
                    else
                        RValue = (DateTime.Now.Year - BrithDate.Year).ToString() + "年" + (DateTime.Now.Month - BrithDate.Month-1).ToString() + "月";
                }
                else if (DateTime.Now.Month < BrithDate.Month)
                {
                    if (DateTime.Now.Year - BrithDate.Year - 1 == 0)
                    { //eg:出生日期:20111020,当前日期:20120820
                        if (DateTime.Now.Day >= BrithDate.Day)

                        }

                    }
                    else
