DateTime.Now.Month.ToString("d2")
回答by Jon Skeet
Either format the integer with two digits as suggested by Mehrdad, or format the DateTimeitself to give you a two-digit month:
要么按照 Mehrdad 的建议用两位数格式化整数，要么格式化它DateTime本身以给您一个两位数的月份：
DateTime.Now.ToString("MM")

I'm using Selenium Webdriver to test a website and set various vars, strings, etc. at the beginning; this made it a lot simpler:
我正在使用 Selenium Webdriver 测试网站并在开始时设置各种变量、字符串等；这使它变得简单得多：
/* Date strings */
public static string TodayNum = DateTime.Now.ToString("dd"); // e.g 07
public static string ThisMonthNum = DateTime.Now.ToString("MM"); // e.g 03
public static string ThisMonthShort = DateTime.Now.ToString("MMM"); // e.g Mar
public static string ThisMonthLong = DateTime.Now.ToString("MMMM"); // e.g March
public static string ThisYearNum = DateTime.Now.ToString("yyyy"); // e.g 2014
回答by Naveed Mansuri
You could use: DateTime.Now.Month.ToString().PadLeft(2, '0');
你可以使用： DateTime.Now.Month.ToString().PadLeft(2, '0');
It will return: 07
它将返回： 07

You can also convert Month and Day to two digit number by following functions too:
您还可以通过以下功能将月和日转换为两位数：
System.DateTime.Now.Month.ToString("00") //Give 01 for January
System.DateTime.Now.Day.ToString("00")
