blocks|key|1523834|text|在DateTime中，您可以使用.TimeOfDay+-但这将为您提供一个表示一天中的时间(10小时)的TimeSpan。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1523835|entityMap^0|1|8|G|A|1G|8|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|O|8|@]|D|@]|E|$]]]|G|$]]

From a <code>DateTime</code>, you can use <code>.TimeOfDay</code> - but that gives you a <code>TimeSpan</code> representing the time into the day (10 hours).

blocks|key|1524156|text|在C#中只有DateTime类型，它由date和time部分组成。如果您不关心DateTime的日期部分，请将其设置为默认值，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1524157|DateTime+myTime+=+default(DateTime).Add(myDateTime.TimeOfDay)|code-block|syntax|javascript|1524158|这样，即使微软决定将基准日期更改为1/1/0001以外的其他日期，您也可以在所有版本的.NET中保持一致。|1524159|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

There is only DateTime type in C# and it consist of both the date and time portion. If you don't care about the Date portion of DateTime, set it to default value like this:

<pre><code>DateTime myTime = default(DateTime).Add(myDateTime.TimeOfDay)
</code></pre>

This way you can be consistent across all versions of .NET, even if Microsoft decides to change the base date to something else than 1/1/0001.

blocks|key|1523895|text|您可能需要研究一下DateTime.ToShortTimeString()方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1523896|此外，DateTime对象上还有许多其他方法和属性，可以帮助您以您喜欢的任何方式格式化日期或时间。只需查看文档即可。|1523897|entityMap|0|LINK|mutability|MUTABLE|url|http://msdn.microsoft.com/en-us/library/system.datetime.toshorttimestring.aspx|1|http://msdn.microsoft.com/en-us/library/system.datetime_members.aspx^0|9|S|0|0|3|8|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

Also, there many other methods and properties on the <a href="http://msdn.microsoft.com/en-us/library/system.datetime_members.aspx" rel="noreferrer">DateTime</a> object that can help you in formating the date or time in any way you like. Just take a look at the documentation.

blocks|key|1524176|text|试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1524177|TimeSpan+TodayTime+=+DateTime.Now.TimeOfDay;|code-block|syntax|javascript|1524178|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Try this:

<pre><code>TimeSpan TodayTime = DateTime.Now.TimeOfDay;

blocks|key|1524043|text|有不同的方法可以做到这一点。您可以使用DateTime.Now.ToLongTimeString()，它只返回字符串格式的时间。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1524044|entityMap^0|J|V|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

There are different ways to do so. You can use <code>DateTime.Now.ToLongTimeString()</code> which
returns only the time in string format.

You can use this

<pre><code>lblTime.Text = DateTime.Now.TimeOfDay.ToString(); 
</code></pre>

It is realtime with milliseconds value and it sets to time only.

blocks|key|1524089|text|这对我很有效。当我不得不使用DateTime.Date来获取日期部分时，我发现了它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1524090|var+wholeDate+=+DateTime.Parse("6/22/2009+10:00:00+AM");
var+time+=+wholeDate+-+wholeDate.Date;|code-block|syntax|javascript|1524091|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

This works for me. I discovered it when I had to work with DateTime.Date to get only the date part.

<pre><code>var wholeDate = DateTime.Parse("6/22/2009 10:00:00 AM");
var time = wholeDate - wholeDate.Date;
</code></pre>

blocks|key|1524098|text|可以长时间使用ToString("T")，短时间使用ToString("t")。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1524099|entityMap^0|7|D|Q|D|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

You can use <code>ToString("T")</code> for long time or <code>ToString("t")</code> for short time.

blocks|key|1308903|text|如果你想要比较时间，而不是日期，你可以只有一个标准的比较日期，或者与你正在使用的日期相匹配，比如...|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1308904|DateTime+time+=+DateTime.Parse("6/22/2009+10:00AM");
DateTime+compare+=+DateTime.Parse(time.ToShortDateString()+%2B+"+2:00PM");
bool+greater+=+(time+>+compare);|code-block|syntax|javascript|1308905|也许有更好的方法可以做到这一点，但要让你的约会保持一致。|1308906|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

If you're looking to compare times, and not the dates, you could just have a standard comparison date, or match to the date you're using, as in...

<pre><code>DateTime time = DateTime.Parse("6/22/2009 10:00AM");
DateTime compare = DateTime.Parse(time.ToShortDateString() + " 2:00PM");
bool greater = (time &gt; compare);
</code></pre>

There may be better ways to to this, but keeps your dates matching.

blocks|key|1524207|text|如果你使用的是gridview，那么你只能用DataFormatString="{0:t}"来显示时间示例：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1524208|++++By+bind+the+value:-
<asp:Label+ID="lblreg"+runat="server"+Text='<%25#Eval("Registration_Time+",+"{0:t}")+%25>'></asp:Label>

if you are using gridview then you can show only the time with <code>DataFormatString="{0:t}"</code>
example: 

<pre><code> By bind the value:-
&lt;asp:Label ID="lblreg" runat="server" Text='&lt;%#Eval("Registration_Time ", "{0:t}") %&gt;'&gt;&lt;/asp:Label&gt;

By bound filed:-
&lt;asp:BoundField DataField=" Registration_Time" HeaderText="Brithday" SortExpression=" Registration Time " DataFormatString="{0:t}"/&gt;
</code></pre>

blocks|key|1524288|text|你也需要考虑到DateTime的种类。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1524289|public+static+DateTime+GetTime(this+DateTime+d)
{
++++return+new+DateTime(d.TimeOfDay.Ticks,+d.Kind);

You need to account for DateTime Kind too.

<pre><code>public static DateTime GetTime(this DateTime d)
{
 return new DateTime(d.TimeOfDay.Ticks, d.Kind);
}
</code></pre>

Suppose I have the value 6/22/2009 10:00:00 AM. How do I get only 10:00 Am from this date time.

How to get only time from date-time C#
