使用datetime.now以YYYYMM格式检索年份和月份

Question

我需要YYYYMM格式的年份和月份.我正在尝试使用

string yrmm = DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString();

但这会返回'20114'而不是'201104'.任何简单的方法来解决这个问题

t ---> Short Time ---> 21:08
T ---> Long Time ---> 21:08:59
f ---> Full date and time ---> 08 April 2007 21:08
F ---> Full date and time (long) ---> 08 April 2007 21:08:59
g ---> Default date and time ---> 08/04/2007 21:08
G ---> Default date and time (long) ---> 08/04/2007 21:08:59
M ---> Day / Month ---> 08 April
r ---> RFC1123 date ---> Sun, 08 Apr 2007 21:08:59 GMT
s ---> Sortable date/time ---> 2007-04-08T21:08:59
u ---> Universal time, local timezone ---> 2007-04-08 21:08:59Z
Y ---> Month / Year ---> April 2007
dd ---> Day ---> 08
ddd ---> Short Day Name ---> Sun
dddd ---> Full Day Name ---> Sunday

HH ---> 2 digit hour (24 hour) ---> 21
mm ---> 2 digit minute ---> 08
MM ---> Month ---> 04
MMM ---> Short Month name ---> Apr
MMMM ---> Month name ---> April
ss ---> seconds ---> 59
tt ---> AM/PM ---> PM
yy ---> 2 digit year ---> 07
yyyy ---> 4 digit year ---> 2007
: ---> seperator, e.g. {0:hh:mm:ss} ---> 09:08:59
