I'll put everything together into one answer:

You could do something like this:

<pre><code> string urlSafeDateString = HttpServerUtility.UrlTokenEncode(date.ToUniversalTime().ToString(System.Globalization.CultureInfo.InvariantCulture).ToCharArray());

 DateTime date = DateTime.Parse(new string(HttpServerUtility.UrlTokenDecode(urlSafeDateString)), System.Globalization.CultureInfo.InvariantCulture).ToLocalTime();
</code></pre>

Or you could do something like this:

<pre><code> string urlSafeDateString = date.ToUniversalTime().ToString("yyyyMMddTHHmmss", System.Globalization.CultureInfo.InvariantCulture);

 DateTime date = DateTime.ParseExact(urlSafeDateString, "yyyyMMddTHHmmss", System.Globalization.CultureInfo.InvariantCulture).ToLocalTime();
</code></pre>

It's probably not part of any standard or anything like that, but you could always use a <a href="http://en.wikipedia.org/wiki/Unix_timestamp" rel="nofollow noreferrer">Unix timestamp</a> as those only contain digits.

blocks|key|1256207|text|实际上，我们有一个报告解决方案，其中日期和时间可以作为纯文本CCYYMMDD和hhmmss值传入，然后，当代码需要对这些值执行任何操作时，它只需使用字符串操作将它们转换回可以显示或容易解析的格式(例如DB2+ISO格式CCYY+DD或hh.mm.ss)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1256208|结果是可读的，如果.NET没有能够很容易做到这一点的字符串操作指令，我会感到惊讶。|1256209|entityMap^0|U|8|13|6|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|O|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|P|8|@]|D|@]|E|$]]]|I|$]]

We actually have a reporting solution where dates and times can be passed in as plain text <code>CCYYMMDD</code> and <code>hhmmss</code> values then, when the code needs to do anything to those values, it simply uses string operations to turn them back into a format that can be displayed or easily parsed (such as the DB2 ISO formats CCYY-MM-DD or hh.mm.ss).

The result is readable and I'd be surprised if .NET didn't have string manipulation instructions that could do this easily.

<blockquote>

</blockquote>

There's a constructor for DateTime that takes the number of ticks: 

<pre><code> DateTime d = new DateTime(634028202671420663);
</code></pre>

There's also an override that lets you map that to either local or UTC time. It's all in the docs: <a href="http://msdn.microsoft.com/en-us/library/system.datetime.datetime.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/system.datetime.datetime.aspx</a>

Edit: realised from the wording of the post that perhaps you're talking about ASP converting the ticks automatically to a DateTime, rather than having to read the numeric parameter. Perhaps! :-)

blocks|key|1258037|text|我刚刚遇到了同样的问题，并使用以下助手方法解决了这个问题：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1258038|++++private+string+Encode(DateTime+date)
++++{
++++++++var+formattedDate+=+date.ToString("yyyy-MM-ddTHH:mm:ss",+System.Globalization.CultureInfo.InvariantCulture);

I've just come across this same problem and solved it with the following helper method:

<pre><code> private string Encode(DateTime date)
 {
 var formattedDate = date.ToString("yyyy-MM-ddTHH:mm:ss", System.Globalization.CultureInfo.InvariantCulture);
 return WebUtility.UrlEncode(formattedDate);
 }
</code></pre>

After using the output in a URL query parameter the value gets correctly deserialised by .NET into DateTime objects passed into my Web API Service.

Looking at the <a href="http://msdn.microsoft.com/en-us/library/system.globalization.datetimeformatinfo.aspx" rel="noreferrer">DateTimeFormatInfo</a> documentation, it appears that all the standard formats have colons in them, which makes passing them on a url unpleasant/impossible.

Is there a standardized format for passing a datetime on a url, preferably one that can be automatically parsed by .NET?

<hr>

Update: A little clarification

The consumer of this data is going to be web service of some kind - it'll either be a simple HTTP GET with this value in the querystring, or it'll be REST with the value in the url somewhere.

<a href="http://en.wikipedia.org/wiki/ISO_8601#Combined_date_and_time_representations" rel="noreferrer">ISO 8601</a> governs date/time formatting, and according to the wiki article, using <code>ToString("yyyyMMddTHHmmssZ")</code> should be standards-compliant at least. Unfortunately, it doesn't get picked up automatically by ASP.NET MVC (haven't tried anything else yet). For what it's worth, ASP.NET MVC won't automatically convert ticks to a datetime either, which surprised me.

Is there a standard date/time format that can be passed on a URL?
