asp.net in asp.net, m$ provides us with an object called DateTime, which we use to get the current time. Like what:
DateTime Dt=datetime.now;
In the above program we made a 24 time object called DT, if we want to get a 12-system time object, we can use another statement
DateTime Dt=datetime.today;
But whether it's now or today, the time we get is just a 2001-03-27t00:57:09 time figure. Perhaps in general this time is sufficient (for example, we're just getting the current time, but in real life we need more than just this big string of numbers, we need to get the exact number of seconds, minutes, moments, and so on, and then this whole bunch of numbers isn't all we need, The ASP's time function also provides us with objects such as Second,minute,hour, but in asp.net, this is not. I have seen friends in order to get a specific minute, and write a function of the DateTime.Now string separated from the time you want. When we do not know the use of datetime, there is no way to do so.
Fortunately, m$ provides the format method for us, using our ability to quickly get the time format we want.
The Format method is:
public string Format (
string format,
Iserviceobjectprovider SP
);
Format refers to the formatting we specify, it has a lot of values, I have to list:
Standard format format formats
D mm/dd/yyyy (2001-3-27)
D dddd, MMMM DD, yyyy such as (March 27, 2001)
F dddd, MMMM dd, yyyy hh:mm (March 27, 2001 0:00)
F dddd, MMMM dd, yyyy HH:mm:ss (March 27, 2001 0:00:00)
G mm/dd/yyyy hh:mm (2001-3-27-0:00)
G mm/dd/yyyy HH:mm:ss (2001-3-27-0:00:00)
M, M MMMM DD (March 27)
R, R ddd, dd MMM yyyy HH ': ' mm ': ' ss ' GMT ' such as (Mon, Mar 2001 16:00:00 GMT)
S yyyy-mm-dd HH:mm:ss seems to be unable to use
T hh:mm as (0:00)
T HH:mm:ss as (0:00:00)
U yyyy-mm-dd HH:mm:ss (2001-03-26 16:00:00z)
U dddd, MMMM dd, yyyy HH:mm:ss (March 26, 2001 16:00:00)
Y, y MMMM, yyyy (March 2001)
Custom formatting list format pattern Description

The following is an example of a simple operation.
<% @ Page language= "C #"%>
<% @ Import namespace= "System.Data"%>
<script language= "C #" runat= "Server" >
public void Page_Load (Object Src,eventargs E)
{
DateTime dt = DateTime.Now;
CTime. Text=dt. Format ("MM", null). ToString ();
}
</script>
<title></title>
<body>
<asp:label id= "CTime" runat= "Server"/>
</body>
