推荐答案

.NET框架轻轻地为您提供TimeSpan结构[

The .NET framework gently provides you the TimeSpan struct [^].
:)

您可以使用TimeSpan

这是它的一个例子

you can use TimeSpan

here is one example of it

public string getFormattedTimeFromSecond(double second)
    {

        TimeSpan t = TimeSpan.FromSeconds(second);

        string formatedTime = string.Format("{0:D2}H:{1:D2}M:{2:D2}S",
                                t.Hours,
                                t.Minutes,
                                t.Seconds);

        return formatedTime;
}

您可以使用以下代码:

Hi,

you can use the following code:

DateTime currentDate = DateTime.Now;
DateTime postedDate = DateTime.Now.AddHours(-2);
TimeSpan ts = postedDate.Subtract (currentDate);

然后您可以使用TimeSpan来显示所需的文本；
