How do i convert HH:MM:SS into just seconds using C#.net?
提问by Andrew
Is there a tidy way of doing this rather than doing a split on the colon's and multipling out each section the relevant number to calculate the seconds?
有没有一种整洁的方法来做到这一点，而不是在冒号上进行拆分并将每个部分乘以相关数字来计算秒数？

It looks like a timespan. So simple parse the text and get the seconds.
它看起来像一个时间跨度。如此简单地解析文本并获得秒数。
string time = "00:01:05";
double seconds = TimeSpan.Parse(time).TotalSeconds;

TimeSpan.Parse() will parse a formatted string.
TimeSpan.Parse() 将解析格式化的字符串。
So
所以
TimeSpan.Parse("03:33:12").TotalSeconds;

You can use the parse method on aTimeSpan.
您可以在 aTimeSpan 上使用 parse 方法。

TimeSpan ts = TimeSpan.Parse( "10:20:30" );
double totalSeconds = ts.TotalSeconds;
The TotalSeconds property returns the total seconds if you just want the seconds then use the seconds property
如果您只想要秒数，则 TotalSeconds 属性返回总秒数，然后使用 seconds 属性
int seconds = ts.Seconds;
Seconds return '30'. TotalSeconds return 10 * 3600 + 20 * 60 + 30
秒返回“30”。TotalSeconds 返回 10 * 3600 + 20 * 60 + 30

This code allows the hours and minutes components to be optional. For example,
此代码允许小时和分钟组件是可选的。例如，
"30" -> 24 seconds
"1:30" -> 90 seconds
"1:1:30" -> 3690 seconds
"30" -> 24 秒
"1:30" -> 90 秒
"1:1:30" -> 3690 秒
int[] ssmmhh = {0,0,0};
var hhmmss = time.Split(':');
var reversed = hhmmss.Reverse();
int i = 0;
reversed.ToList().ForEach(x=> ssmmhh[i++] = int.Parse(x));
var seconds = (int)(new TimeSpan(ssmmhh[2], ssmmhh[1], ssmmhh[0])).TotalSeconds;

//Added code to handle invalid strings
string time = null; //"";//"1:31:00";
string rv = "0";
TimeSpan result;
if(TimeSpan.TryParse(time, out result))
{
rv = result.TotalSeconds.ToString();
}
retrun rv;
