我要评论复制代码 代码如下:
public static string datediff(datetime datetime1, datetime datetime2)
{
string datediff = null;
int date = 0;
try
{
int year = convert.toint32(datetime2.tostring("yyyy")) - convert.toint32(datetime1.tostring("yyyy"));
timespan ts = datetime2 - datetime1;
string t1 = datetime1.tostring("yyyy-mm-dd");
string t2 = datetime2.tostring("yyyy-mm-dd");
datetime d1 = datetime.parse(t1);
datetime d2 = datetime.parse(t2);
timespan ts2 = d2 - d1;
date = ts2.days;
if (date == 0)
{
if (ts.hours > 1)
{
datediff = ts.hours.tostring() + "小时前";
}
else
{
if (ts.minutes > 1)
{
datediff = ts.minutes.tostring() + "分钟前";
}
else
{
datediff = ts.seconds.tostring() + "秒前";
}
}
}
else
{
if (date == 1)
{
datediff = "昨天";
}
else
{
if (date == 2)
{
datediff = "前天";
}
else
{
if (year == 0)
{
datediff = datetime1.month.tostring() + "月" + datetime1.day.tostring() + "日";
}
else
{
datediff = datetime1.year.tostring() + "年" + datetime1.month.tostring() + "月" + datetime1.day.tostring() + "日";
}
}
}
}
}
catch
{ }
return datediff;
}
