网上有用C#后台实现的方法，为方便查看就转贴到下面吧：）
代码如下:
public string DateStringFromNow(DateTime dt)
{
TimeSpan span = DateTime.Now - dt;
if (span.TotalDays >60)
{
return dt.ToShortDateString();
}
else
if ( span.TotalDays >30 )
{
return
"1个月前";
}
else
if (span.TotalDays >14)
{
return
"2周前";
}
else
if (span.TotalDays >7)
{
return
"1周前";
}
else
if (span.TotalDays >1)
{
return
string.Format("{0}天前", (int)Math.Floor(span.TotalDays));
}
else
if (span.TotalHours >1)
{
return
string.Format("{0}小时前", (int)Math.Floor(span.TotalHours));
}
else
if (span.TotalMinutes >1)
{
return
string.Format("{0}分钟前", (int)Math.Floor(span.TotalMinutes));
}
else
if (span.TotalSeconds >=1)
{
return
string.Format("{0}秒前", (int)Math.Floor(span.TotalSeconds));
}
else
{
return
"1秒前";
}
}
