You can use string.format, then parse it like this:
您可以使用 string.format，然后像这样解析它：
double.Parse(string.Format("-HH.mm"))

Do not repeat this at home!
不要在家里重复这个！
double value = (timeSpan.Hours + timeSpan.Minutes / 100.0 + timeSpan.Seconds / 10000.0) * (timeSpan > TimeSpan.Zero ? 1 : -1);

You could use TimeSpan.TotalMinutes(gets the value of the current TimeSpanstructure expressed in whole and fractional minutes) or other similar properties.
您可以使用TimeSpan.TotalMinutes(获取TimeSpan以整数和小数分钟表示的当前结构的值) 或其他类似属性。

Despite how ambiguous this question is, for future reference, Umar was probably the closest to answering the question, as it was displayed in the title.
尽管这个问题有多么模棱两可，但为了将来参考，奥马尔可能是最接近回答这个问题的人，因为它显示在标题中。
To get a doublefrom a TimeSpanobject, you need to pick the most significant measurement, and get the total. As the Total<x>property, will return the appropriate full value, and the fractions of that value as a decimal.
为了得到一个double从TimeSpan对象，你需要选择最显著的测量，并获得总。作为Total<x>属性，将返回适当的完整值，并将该值的分数作为小数。
So, if you want 8:15:00, to a double- and the "8"represents Hours, then you'll want TimeSpan.TotalHourswhich will result in a value of 8.25.
因此，如果您想要8:15:00, 到 a double- 和"8"代表Hours，那么您将希望TimeSpan.TotalHours得到 8.25 的值。
If the "8"represents Minutes, then again, you'll use the appropriate property TimeSpan.TotalMinutesfor the same result, and so on.
如果"8"代表Minutes，那么您将再次使用适当的属性TimeSpan.TotalMinutes来获得相同的结果，依此类推。
