C\#中一些日期格式的转换。

创建公共方法类（UtilityHandle.cs），代表如下：

/// <summary>
    /// 公共方法类
    /// </summary>
    public static class UtilityHandle
    {
        /// <summary>
        ///  字符串日期转DateTime
        /// </summary>
        public static DateTime TransStrToDateTime(string strDateTime)
        {
            DateTime now;
            string[] format = new string[] 
            { 
                "yyyyMMddHHmmss", "yyyy-MM-dd HH:mm:ss", "yyyy年MM月dd日 HH时mm分ss秒",
                "yyyyMdHHmmss","yyyy年M月d日 H时mm分ss秒", "yyyy.M.d H:mm:ss", "yyyy.MM.dd HH:mm:ss","yyyy-MM-dd","yyyyMMdd"
                ,"yyyy/MM/dd","yyyy/M/d"
            };
            if (DateTime.TryParseExact(strDateTime, format, CultureInfo.InvariantCulture, DateTimeStyles.None, out now))
            {
                return now;
            }
            return DateTime.MinValue;
        }
    
        /// <summary>
        /// 日期转换
        /// </summary>
        public static string TransformDataLong(DateTime? dateTime)
        {
            string result = "";
            if (dateTime.HasValue)
            {
                result = dateTime.Value.ToString("yyyy-MM-dd HH:mm:ss");
            }
            return result;
        }
    
        /// <summary>
        /// 日期转换
        /// </summary>
        public static string TransformDataShort(DateTime? dateTime)
        {
            string result = "";
            if (dateTime.HasValue)
            {
                result = dateTime.Value.ToString("yyyy-MM-dd");
            }
            return result;
        }
    
        /// <summary>
        /// 将日期转换成decimal
        /// </summary>
        public static decimal TransDateTimeToDecimal(DateTime date)
        {
            decimal ret = 0;
            ret = Convert.ToDecimal(date.ToString("yyyyMMddHHmmss"));
            return ret;
        }
    
        /// <summary>
        /// 将decimal转换成日期格式
        /// </summary>
        /// <param name="date">yyyyMMddHHmmss</param>
        /// <returns>yyyy-MM-dd HH:mm:ss</returns>
        public static string TransDecimalToDateTime(string date)
        {
            DateTimeFormatInfo dtfi = new CultureInfo("zh-CN", false).DateTimeFormat;
            DateTime dateTime = DateTime.Now;
            DateTime.TryParseExact(date, "yyyyMMddHHmmss", dtfi, DateTimeStyles.None, out dateTime);
            return dateTime.ToString("yyyy-MM-dd HH:mm:ss"); ;
        }
    }
