DateTime time=DateTime.Now;   //2010-5-28  11:22:02.4552691 星期五               ime.To("y")                         "2010年5月"               time.To("yy")                       "10"               time.To("yyy")                     "2010"               time.To("yyyy")                    "2010"               time.To("Y")                        "2010年5月"               time.To("m")                       "5月28日"               time.To("mm")                     "22"               time.To("mmm")                  "22"               time.To("mmmm")               "22"               time.To("M")                      "5月28日"               time.To("MM")                   "05"               time.To("MMM")                "五月"               time.To("MMMM")             "五月"               time.To("d")                         "2010-5-28"               time.To("dd")                       "28"               time.To("ddd")                     "五"               time.To("dddd")                   "星期五"               time.To("D")                        "2010年5月28日"               time.To("hh")                        "11"               time.To("hhh")                      "11"               time.To("hhhh")                     "11"               time.To("HH")                      "11"               time.To("HHH")                    "11"               time.To("HHHH")                 "11"               time.To("s")                         "2010-05-28T11:22:02"               time.To("ss")                       "02"               time.To("sss")                      "02"               time.To("ssss")                    "02"               time.To("f")                         "2010年5月28日 11:22"               time.To("ff")                        "45"               time.To("fff")                       "455"               time.To("ffff")                      "4552"               time.To("t")
