You can use the ToStringmethod with the appropriate formatting string:
var time = date.ToString("H:mm");
回答by Soner G?nül
You can use "H" custom format specifier.
您可以使用 “H”自定义格式说明符。
The "H" custom format specifier represents the hour as a number from 0 through 23; that is, the hour is represented by a zero-based 24-hour clock that counts the hours since midnight. A single-digit hour is formatted without a leading zero.
“H”自定义格式说明符将小时表示为 0 到 23 之间的数字；也就是说，小时由从零开始的 24 小时制表示，该时钟计算自午夜以来的小时数。单位数小时的格式不带前导零。
Nullable<DateTime> data = new DateTime(2007, 6, 15, 5, 23, 45);
Console.WriteLine(data.Value.ToString("H:mm"));
Output will be;
输出将是；
5:23

Nullable<DateTime> data = new DateTime(2007, 6, 15, 5, 23, 45);
var timeofDay = data.Value.TimeOfDay; // 05:23:45
回答by Adeel
var time = date.ToString("H:mm");
Hhere represents 24 hour time. i.e. 0-23
H这里代表24小时时间。即 0-23

If you need to get a TimeSpantype, use the property in DateTime class called TimeOfDay. It returns only the "time" part.
如果需要获取TimeSpan类型，请使用 DateTime 类中名为TimeOfDay. 它只返回“时间”部分。
If you need to get a string in that format, using TimeOfDay is an overkill and simply use ToString("hh:mm")to format your output. If you don't want results like 05:40, use ToString("H:mm").
如果您需要以该格式获取字符串，则使用 TimeOfDay 是一种矫枉过正，仅用于ToString("hh:mm")格式化输出。如果您不想要像 那样的结果05:40，请使用ToString("H:mm")。

strange, it works fine for me, maby it's a setting in visual studio?
奇怪，它对我来说很好用，也许这是 Visual Studio 中的设置？
You can try this
你可以试试这个
Nullable<DateTime> data = new DateTime(2007, 6, 15, 5, 23, 45);
Debug.Write(data.Value.Hour + ":" + data.Value.Minute);
