blocks|key|1406204|text|一种方法是创建一个DateTime对象并将其用于格式化：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1406205|new+DateTime(myTimeSpan.Ticks).ToString(myCustomFormat)

//+or+using+String.Format:
String.Format("{0:HHmmss}",+new+DateTime(myTimeSpan.Ticks))|code-block|syntax|javascript|1406206|这就是我知道的方式。我希望有人能提出一个更好的方法。|1406207|entityMap^0|9|8|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|S|8|@]|D|@]|E|$]]|$1|M|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|N|$]]

One way is to create a <code>DateTime</code> object and use it for formatting:

<pre><code>new DateTime(myTimeSpan.Ticks).ToString(myCustomFormat)

// or using String.Format:
String.Format("{0:HHmmss}", new DateTime(myTimeSpan.Ticks))
</code></pre>

This is the way I know. I hope someone can suggest a better way.

I used the code below. It is long, but still it is one expression, and produces very friendly output, as it does not outputs days, hours, minutes, or seconds if they have value of zero.

In the sample it produces output: "4 days 1 hour 3 seconds".

<pre><code>TimeSpan sp = new TimeSpan(4,1,0,3);
string.Format("{0}{1}{2}{3}", 
 sp.Days &gt; 0 ? ( sp.Days &gt; 1 ? sp.ToString(@"d\ \d\a\y\s\ "): sp.ToString(@"d\ \d\a\y\ ")):string.Empty,
 sp.Hours &gt; 0 ? (sp.Hours &gt; 1 ? sp.ToString(@"h\ \h\o\u\r\s\ ") : sp.ToString(@"h\ \h\o\u\r\ ")):string.Empty,
 sp.Minutes &gt; 0 ? (sp.Minutes &gt; 1 ? sp.ToString(@"m\ \m\i\n\u\t\e\s\ ") :sp.ToString(@"m\ \m\i\n\u\t\e\ ")):string.Empty,

 StringBuilder readableTime = new StringBuilder();

 else
 values[0] = span.Days.ToString() + " dagen"; //days

 readableTime.Append(values[0]);
 readableTime.Append(", ");
 }
 else
 values[0] = String.Empty;


 if (span.Hours &gt; 0)
 {
 if (span.Hours == 1)
 values[1] = span.Hours.ToString() + " uur"; //hour
 else
 values[1] = span.Hours.ToString() + " uren"; //hours

 readableTime.Append(values[1]);
 readableTime.Append(", ");

 }
 else
 values[1] = string.Empty;

 values[2] = span.Minutes.ToString() + " minuut"; //minute

I wanted to return a string such as "1 day 2 hours 3 minutes" and also take into account if for example days or minuttes are 0 and then not showing them. thanks to <a href="https://stackoverflow.com/a/840177/5788969">John Rasch</a> for his answer which mine is barely an extension of

<pre><code>TimeSpan timeLeft = New Timespan(0, 70, 0);
String.Format("{0}{1}{2}{3}{4}{5}",
 Math.Floor(timeLeft.TotalDays) == 0 ? "" : 
 Math.Floor(timeLeft.TotalDays).ToString() + " ",
 Math.Floor(timeLeft.TotalDays) == 0 ? "" : Math.Floor(timeLeft.TotalDays) == 1 ? "day " : "days ",

Here is my <a href="https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/extension-methods" rel="nofollow noreferrer">extension method</a>:

<pre><code>public static string ToFormattedString(this TimeSpan ts)
{
 const string separator = ", ";

 if (ts.TotalMilliseconds &lt; 1) { return "No time"; }

 return string.Join(separator, new string[]
 {
 ts.Days &gt; 0 ? ts.Days + (ts.Days &gt; 1 ? " days" : " day") : null,
 ts.Hours &gt; 0 ? ts.Hours + (ts.Hours &gt; 1 ? " hours" : " hour") : null,
 ts.Minutes &gt; 0 ? ts.Minutes + (ts.Minutes &gt; 1 ? " minutes" : " minute") : null,
 ts.Seconds &gt; 0 ? ts.Seconds + (ts.Seconds &gt; 1 ? " seconds" : " second") : null,
 ts.Milliseconds &gt; 0 ? ts.Milliseconds + (ts.Milliseconds &gt; 1 ? " milliseconds" : " millisecond") : null,
 }.Where(t =&gt; t != null));
}
</code></pre>

Example call:

<pre><code>string time = new TimeSpan(3, 14, 15, 0, 65).ToFormattedString();
</code></pre>

Output:

<pre><code>3 days, 14 hours, 15 minutes, 65 milliseconds

This is a pain in VS 2010, here's my workaround solution.

<pre><code> public string DurationString
 {
 get 
 {
 if (this.Duration.TotalHours &lt; 24)
 return new DateTime(this.Duration.Ticks).ToString("HH:mm");
 else //If duration is more than 24 hours
 {
 double totalminutes = this.Duration.TotalMinutes;
 double hours = totalminutes / 60;
 double minutes = this.Duration.TotalMinutes - (Math.Floor(hours) * 60);
 string result = string.Format("{0}:{1}", Math.Floor(hours).ToString("00"), Math.Floor(minutes).ToString("00"));
 return result;
 }
 } 
 }

blocks|key|1407050|text|当您只需要小时:分钟:秒时，Substring方法可以完美地工作。它是简单的，干净的代码，易于理解。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1407051|++++var+yourTimeSpan+=+DateTime.Now+-+DateTime.Now.AddMinutes(-2);

The <code>Substring</code> method works perfectly when you only want the Hours:Minutes:Seconds. It's simple, clean code and easy to understand. 

<pre><code> var yourTimeSpan = DateTime.Now - DateTime.Now.AddMinutes(-2);

 var formatted = yourTimeSpan.ToString().Substring(0,8);// 00:00:00 

 Console.WriteLine(formatted);
</code></pre>

blocks|key|1407094|text|还没有人展示使用十进制格式说明符的方法，这是我最喜欢的一种，特别是在使用字符串插值时-+https://docs.microsoft.com/en-us/dotnet/standard/base-types/standard-numeric-format-strings?redirectedfrom=MSDN#decimal-format-specifier-d|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1407095|例如：|1407096|$"{time.Hours:D2}:{time.Minutes:D2}:{time.Seconds:D2}.{time.Milliseconds:D3}"

No one has shown approach with decimal format specifier which is my favorite one, especially when used with string interpolation - <a href="https://docs.microsoft.com/en-us/dotnet/standard/base-types/standard-numeric-format-strings?redirectedfrom=MSDN#decimal-format-specifier-d" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/dotnet/standard/base-types/standard-numeric-format-strings?redirectedfrom=MSDN#decimal-format-specifier-d</a>
For example:
<pre class="lang-cs prettyprint-override"><code>$&quot;{time.Hours:D2}:{time.Minutes:D2}:{time.Seconds:D2}.{time.Milliseconds:D3}&quot;
// Sample output: 00:00:09.200
</code></pre>
You can of course wrap it up in some helper method.

What is the recommended way of formatting <code>TimeSpan</code> objects into a string with a custom format?

How can I String.Format a TimeSpan object with a custom format in .NET?
