DateTime birthDate = new DateTime(1981, 8, 9);
Console.WriteLine ("I was born on the {0}. of {1}, {2}.", birthDate.Day, birthDate.ToString("MMMM"), birthDate.Year);

/* The above code will say:
"I was born on the 9. of august, 1981."

"dd" converts to the day (01 thru 31).
"ddd" converts to 3-letter name of day (e.g. mon).
"dddd" converts to full name of day (e.g. monday).
"MMM" converts to 3-letter name of month (e.g. aug).
"MMMM" converts to full name of month (e.g. august).
"yyyy" converts to year.
*/

It's

DateTime.Now.ToString("MMMM");

有4个Ms。

使用"MMMM"自定义格式说明符:

DateTime.Now.ToString("MMMM");

Debug.writeline(Format(Now, "dd MMMM yyyy"))

DateTime birthDate = new DateTime(1981, 8, 9);
Console.WriteLine ("I was born on the {0}. of {1}, {2}.", birthDate.Day, birthDate.ToString("MMMM"), birthDate.Year);

/* The above code will say:
"I was born on the 9. of august, 1981."

"dd" converts to the day (01 thru 31).
"ddd" converts to 3-letter name of day (e.g. mon).
"dddd" converts to full name of day (e.g. monday).
"MMM" converts to 3-letter name of month (e.g. aug).
"MMMM" converts to full name of month (e.g. august).
"yyyy" converts to year.

如果你想要当月的，你可以使用 DateTime.Now.ToString("MMMM")获取完整月份或DateTime.Now.ToString("MMM")获取缩写月份。

如果你有其他想要获取月份字符串的日期，在它加载到DateTime对象后，你可以在该对象中使用相同的函数: dt.ToString("MMMM")获取完整的月份，或dt.ToString("MMM")获取缩写的月份。
