c# - DateTime specifier with spaces

Question

I have for example following date time

 DateTime dt = new DateTime(2013,18,04,22,23,0);

this date should be represented like

18-04-2013 22:23    Environment.NewLine

Worth to mention is there are spaces between number 3 (of 22:23) and Environment.NewLine. So, field length is 20characters from beginning to E letter (of Environment.NewLine).

How can I represent date in this format with spaces?

Answer 1

我将使用标准日期格式和非特定日期字符串格式代码的组合：

string.Format("{0:MM-dd-yyyy HH:mm}    \n", dt);

或者如果长度“20”很重要：

string.Format("{0,-20:MM-dd-yyyy HH:mm}\n", dt);

这有效地将字符串“填充”为 20 个字符并左对齐。这样，即使有人决定更改日期格式（例如，不要用零填充），您仍然只有 20 个字符

Answer 2

string.Format("{0,-20}  {1}", DateTime.ToString("MM-dd-yyyy HH:mm"), Environment.NewLine);

Answer 3

假设您修复了DateTime作业，因此月份在前一天：

DateTime dt = new DateTime(2013, 4, 18, 22, 23, 0);
String.Format("{0,-20}{1}",
    dt.ToString("dd-MM-yyyy HH:mm"),
    "Environment.NewLine" //*/ Environment.NewLine // Whichever you want
);

Format允许您在格式化程序中指定空格填充，因此{0,-20}表示以 20 个字符的列显示，左对齐。同样，{0,20}会做 20 个字符，右对齐。
