Question

Is there a way to convert a given value to elapsed time with a formatting string in .NET? For example, if I have value 4000 and formatting string to be "mm:ss", I should get the elapsed time as 66:40.

Thanks Datte

Answer 1

您可使用timeSpan 。

var elapsedTime = TimeSpan.FromSeconds(4000);
var formatted = string.Format("{0}:{1}", (int)elapsedTime.TotalMinutes, elapsedTime.Seconds);

Console.WriteLine(formatted);

(由于你需要一分钟,而不是每天/小时/分钟/分钟,你可以为此使用正常格式)。

Answer 2

Using standard format strings there would be no way to tell which of your format strings are totals and which are component values. For example, should mm produce the total number of minutes, or the minute component? And if it s total, how do we know what the total is? It should be 66.666666 minutes, not 66.
