Contoh

Contoh berikut menunjukkan Compare metode .

DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
int result = DateTime.Compare(date1, date2);
string relationship;

if (result < 0)
   relationship = "is earlier than";
else if (result == 0)
   relationship = "is the same time as";
else
   relationship = "is later than";

Console.WriteLine("{0} {1} {2}", date1, relationship, date2);

// The example displays the following output for en-us culture:
//    8/1/2009 12:00:00 AM is earlier than 8/1/2009 12:00:00 PM
let date1 = DateTime(2009, 8, 1, 0, 0, 0)
let date2 = DateTime(2009, 8, 1, 12, 0, 0)
let result = DateTime.Compare(date1, date2)

let relationship =
    if result < 0 then
        "is earlier than"
    elif result = 0 then
        "is the same time as"
    else
        "is later than"

printfn $"{date1} {relationship} {date2}"
