Instance

program that uses DateTime format [C #]

Using System;

Class Program
{
static void Main ()
{
DateTime time = DateTime.Now; Use current time
string format = "MMM ddd d hh:mm yyyy"; Use this format
Console.WriteLine (Time.  ToString (format)); Write to Console
}
}

Output

Feb Fri 27 11:41 2009

Format string pattern

MMM Display Three-letter Month
DDD Display Three-letter Day of the WEEK
D Display day of the MONTH
HH display two-digit hours on 24-hour scale
MM Display Two-digit minutes
YYYY display Four-digit Year

Another way of doing things

Using System;

Class Program
{
static void Main ()
{
DateTime time = DateTime.Now; Use current time
string format = "M D h:mm yy"; Use this format
Console.WriteLine (Time. ToString (format)); Write to Console
}
}

Output

2 27 11:48 09

Format string pattern

M Display one-digit month number [changed]
D Display One-digit Day of the MONTH [changed]
H display One-digit hour on 12-hour scale [changed]
MM Display Two-digit minutes
YY display two-digit year [changed]

Abroad in commonly used formats

Using System;

Class program
{
    static void Main ()
    {
 datetime now = Datetim E.now;
 console.writeline (now. ToString ("D"));
 console.writeline (now. ToString ("D"));
 console.writeline (now. ToString ("F"));
 console.writeline (now. ToString ("F"));
 console.writeline (now. ToString ("G"));
 console.writeline (now. ToString ("G"));
 console.writeline (now. ToString ("M"));
 console.writeline (now. ToString ("M"));
 console.writeline (now. ToString ("O"));
 console.writeline (now. ToString ("O"));
 console.writeline (now. ToString ("S"));
 console.writeline (now. ToString ("T"));
 console.writeline (now. ToString ("T"));
 console.writeline (now. ToString ("U"));
 console.writeline (now. ToString ("U"));
 console.writeline (now. ToString ("Y"));
 console.writeline (now. ToString ("Y"));
   }
}
