System

Rakitan:

netstandard.dll, System.Runtime.dll

Sumber:

DateTime.cs

Membandingkan dua instans dan mengembalikan bilangan DateTime bulat yang menunjukkan apakah instans pertama lebih awal dari, sama seperti, atau lebih baru dari instans kedua.

public:
 static int Compare(DateTime t1, DateTime t2);

public static int Compare(DateTime t1, DateTime t2);

static member Compare : DateTime * DateTime -> int

Public Shared Function Compare (t1 As DateTime, t2 As DateTime) As Integer

Parameter

t1

DateTime

Objek pertama yang dibandingkan.

t2

DateTime

Objek kedua yang akan dibandingkan.

Mengembalikan

Int32

Angka yang ditandatangani yang menunjukkan nilai relatif dan t1t2.

Jenis Nilai	Keadaan
Kurang dari nol	t1 lebih awal dari t2.
Nol	t1 sama t2dengan .
Lebih besar dari nol	t1 lebih lambat dari t2.

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}"

// 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

Module Example
   Public Sub Main()
      Dim date1 As Date = #08/01/2009 12:00AM#
      Dim date2 As Date = #08/01/2009 12:00PM#
      Dim result As Integer = DateTime.Compare(date1, date2)
      Dim relationship As String
      
      If result < 0 Then
         relationship = "is earlier than"
      ElseIf result = 0 Then
         relationship = "is the same time as"         
      Else
         relationship = "is later than"
      End If
      
      Console.WriteLine("{0} {1} {2}", date1, relationship, date2)
   End Sub
End Module
' The example displays the following output:
'    8/1/2009 12:00:00 AM is earlier than 8/1/2009 12:00:00 PM

Keterangan

Untuk menentukan hubungan dengan t1 , metode membandingkan Ticks properti dan t1t2 tetapi mengabaikan properti merekaKind.Comparet2 Sebelum membandingkan DateTime objek, pastikan bahwa objek mewakili waktu dalam zona waktu yang sama.
