格式.NET日期时间＆QUOT;白天＆QUOT;没有前导零 [英] Format .NET DateTime "Day" with no leading zero

问题描述

有关以下code，我希望的结果的等于2，因为MSDN指出，D再presents月份的一天，从1号经过31个位数的日被格式化不带前导零。

For the following code, I would expect result to equal 2, because the MSDN states that 'd' "Represents the day of the month as a number from 1 through 31. A single-digit day is formatted without a leading zero.".

DateTime myDate = new DateTime( 2009, 6, 4 );
string result = myDate.ToString( "d" );

然而，结果的是实际上等于'2009/6/4 - 这是短日期格式（这也是D）。我可以用DD，但增加了一个前导零，这是我不想要的。

However, result is actually equal to '6/4/2009' - which is the short-date format (which is also 'd'). I could use 'dd', but that adds a leading zero, which I don't want.

推荐答案

要表明这是一个自定义格式说明（相对于标准的格式说明），它必须是两个字符长。这可以通过添加一个空间（这将在输出中显示）来完成，或通过包括百分号单个字母之前，这样的：

To indicate that this is a custom format specifier (in contrast to a standard format specifier), it must be two characters long. This can be accomplished by adding a space (which will show up in the output), or by including a percent sign before the single letter, like this:

string result = myDate.ToString("%d");
