Use DateTime.ToStringwith the specified formatMM.dd.yyyy:
使用DateTime.ToString指定的格式MM.dd.yyyy：
this.TextBox3.Text = DateTime.Now.ToString("MM.dd.yyyy");
Here, MMmeans the month from 01 to 12, ddmeans the day from 01 to 31 and yyyymeans the year as a four-digit number.

Little addition to Jason's answer:
杰森回答的一点补充：
- The
ToShortDateString()is culture-sensitive.
- 该
ToShortDateString()是文化敏感。
From MSDN:
来自 MSDN：
The string returned by the ToShortDateString method is culture-sensitive. It reflects the pattern defined by the current culture's DateTimeFormatInfo object. For example, for the en-US culture, the standard short date pattern is "M/d/yyyy"; for the de-DE culture, it is "dd.MM.yyyy"; for the ja-JP culture, it is "yyyy/M/d". The specific format string on a particular computer can also be customized so that it differs from the standard short date format string.
ToShortDateString 方法返回的字符串区分区域性。它反映了当前区域性的 DateTimeFormatInfo 对象定义的模式。例如，对于 en-US 文化，标准的短日期模式是“M/d/yyyy”；对于 de-DE 文化，它是“dd.MM.yyyy”；对于 ja-JP 文化，它是“yyyy/M/d”。还可以自定义特定计算机上的特定格式字符串，使其不同于标准的短日期格式字符串。
That's mean it's better to use the ToString()method and define format explicitly (as Jason said). Although if this string appeas in UI the ToShortDateString()is a good solution because it returns string which is familiar to a user.
这意味着最好使用该ToString()方法并明确定义格式（如 Jason 所说）。虽然如果这个字符串出现在 UI 中，这ToShortDateString()是一个很好的解决方案，因为它返回用户熟悉的字符串。
- If you need just today's date you can use
DateTime.Today.
- 如果您只需要今天的日期，您可以使用
DateTime.Today.
