我也建议在客户端进行计算。服务器工作更少。

jquery.timeago插件

Jeff，因为Stack Overflow广泛使用jQuery，所以我建议使用jQuery.timeago插件。

优点：

即使页面是在10分钟前打开的，也不要使用“1分钟前”的时间戳；timeago自动刷新。您可以充分利用web应用程序中的页面和/或片段缓存，因为时间戳不是在服务器上计算的。你可以像酷孩子一样使用微格式。

只需将其附加到DOM就绪的时间戳：

jQuery(document).ready(function() {
    jQuery('abbr.timeago').timeago();
});

这将在标题中使用timeago类和ISO 8601时间戳转换所有缩写元素：

<abbr class="timeago" title="2008-07-17T09:24:17Z">July 17, 2008</abbr>

变成这样：

<abbr class="timeago" title="July 17, 2008">4 months ago</abbr>

结果：4个月前。随着时间的推移，时间戳将自动更新。

免责声明：我写了这个插件，所以我有偏见。

您可以使用TimeAgo扩展，如下所示：

public static string TimeAgo(this DateTime dateTime)
{
    string result = string.Empty;
    var timeSpan = DateTime.Now.Subtract(dateTime);
 
    if (timeSpan <= TimeSpan.FromSeconds(60))
    {
        result = string.Format("{0} seconds ago", timeSpan.Seconds);
    }
    else if (timeSpan <= TimeSpan.FromMinutes(60))
    {
        result = timeSpan.Minutes > 1 ? 
            String.Format("about {0} minutes ago", timeSpan.Minutes) :
            "about a minute ago";
    }
    else if (timeSpan <= TimeSpan.FromHours(24))
    {
        result = timeSpan.Hours > 1 ? 
            String.Format("about {0} hours ago", timeSpan.Hours) : 
            "about an hour ago";
    }
    else if (timeSpan <= TimeSpan.FromDays(30))
    {
        result = timeSpan.Days > 1 ? 
            String.Format("about {0} days ago", timeSpan.Days) : 
            "yesterday";
    }
    else if (timeSpan <= TimeSpan.FromDays(365))
    {
        result = timeSpan.Days > 30 ? 
            String.Format("about {0} months ago", timeSpan.Days / 30) : 
            "about a month ago";
    }
    else
    {
        result = timeSpan.Days > 365 ? 
            String.Format("about {0} years ago", timeSpan.Days / 365) : 
            "about a year ago";
    }
 
    return result;
}

或者使用带有Timeago的Razor扩展的jQuery插件。

简单且100%的工作解决方案。

处理过去和将来的时间。。以防万一

我更喜欢这个版本，因为它简洁，并且能够添加新的刻度点。这可以用Timespan的Latest（）扩展来封装，而不是长的1行，但为了发布的简洁，这可以。这修复了一小时前、一小时前的问题，提供了一个小时直到两小时过去
