代码如下：
 1  /// <summary>
 2         /// 格式化时间字符串
 3         /// </summary>
 4         /// <param name="strDate"></param>
 5         /// <returns></returns>
 6         private DateTime StrConvertDateToString(string strDate)
 7         {
 8             return (DateTime.ParseExact(strDate, "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture)); //day
 9 
10         }
11         /// <summary>
12         /// 格式化时间字符串
13         /// </summary>
14         /// <param name="strDate"></param>
15         /// <returns></returns>
16         private string StrDateConvertDateToString(string strDate)
17         {
18             return (DateTime.ParseExact(strDate, "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture)).ToString("yyyy-MM-dd"); //day
19 
20         }
