Artikel
08/20/2007

Vergleicht zwei TimeSpan-Werte und gibt eine ganze Zahl zurück, die das Verhältnis zwischen ihnen angibt.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Shared Function Compare ( _
    t1 As TimeSpan, _
    t2 As TimeSpan _
) As Integer
'Usage
Dim t1 As TimeSpan
Dim t2 As TimeSpan
Dim returnValue As Integer

returnValue = TimeSpan.Compare(t1, t2)

public static int Compare (
    TimeSpan t1,
    TimeSpan t2
)

public:
static int Compare (
    TimeSpan t1, 
    TimeSpan t2
)

public static int Compare (
    TimeSpan t1, 
    TimeSpan t2
)

public static function Compare (
    t1 : TimeSpan, 
    t2 : TimeSpan
) : int

Parameter

t1
Eine TimeSpan.

t2
Eine TimeSpan.

Rückgabewert

Wert	Bedingung
-1	t1 ist kleiner als t2
0	t1 ist gleich t2
1	t1 ist größer als t2

Beispiel

Im folgenden Codebeispiel werden verschiedene TimeSpan-Objekte mithilfe der Compare-Methode mit einer Referenz-TimeSpan verglichen.
