TimeSpan.Compare(TimeSpan, TimeSpan) 方法
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
比較兩個 TimeSpan 值並傳回整數,這個整數會指出第一個值比第二個值短、等長或較長。
public:
static int Compare(TimeSpan t1, TimeSpan t2);
C#
public static int Compare (TimeSpan t1, TimeSpan t2);
static member Compare : TimeSpan * TimeSpan -> int
Public Shared Function Compare (t1 As TimeSpan, t2 As TimeSpan) As Integer
- t1
- TimeSpan
要比較的第一個時間間隔。
- t2
- TimeSpan
要比較的第二個時間間隔。
下列其中一個值。
值 | 描述 |
---|---|
-1 | t1 短於 t2 。
|
0 | t1 等於 t2 。
|
1 | t1 長於 t2 。

下列範例 Compare 會使用方法來比較數個 TimeSpan 物件與 TimeSpan 物件,其值為2小時的時間間隔。
C#
// Define a time interval equal to two hours.
TimeSpan baseInterval = new TimeSpan( 2, 0, 0);
// Define an array of time intervals to compare with
// the base interval.
TimeSpan[] spans = {
TimeSpan.FromSeconds(-2.5),
TimeSpan.FromMinutes(20),
TimeSpan.FromHours(1),
TimeSpan.FromMinutes(90),
baseInterval,
TimeSpan.FromDays(.5),
TimeSpan.FromDays(1)
};
// Compare the time intervals.
foreach (var span in spans) {
int result = TimeSpan.Compare(baseInterval, span);
Console.WriteLine("{0} {1} {2} (Compare returns {3})",
baseInterval,
result == 1 ? ">" : result == 0 ? "=" : "<",
span, result);
}
// The example displays the following output:
// 02:00:00 > -00:00:02.5000000 (Compare returns 1)
// 02:00:00 > 00:20:00 (Compare returns 1)
// 02:00:00 > 01:00:00 (Compare returns 1)
// 02:00:00 > 01:30:00 (Compare returns 1)
// 02:00:00 = 02:00:00 (Compare returns 0)
// 02:00:00 < 12:00:00 (Compare returns -1)
// 02:00:00 < 1.00:00:00 (Compare returns -1)
Public Module Example
Public Sub Main()
' Define a time interval equal to 2 hours.
Dim baseInterval As New TimeSpan( 2, 0, 0)
' Define an array of time intervals to compare with
' the base interval.
Dim spans() As TimeSpan = { TimeSpan.FromSeconds(-2.5),
TimeSpan.FromMinutes(20),
TimeSpan.FromHours(1),
TimeSpan.FromMinutes(90),
baseInterval,
TimeSpan.FromDays(.5),
TimeSpan.FromDays(1) }
' Compare the time intervals.
For Each span In spans
Dim result As Integer = TimeSpan.Compare(baseInterval, span)
Console.WriteLine("{0} {1} {2} (Compare returns {3})",
baseInterval,
If(result = 1, ">", If(result = 0, "=", "<")),
span, result)
Next
End Sub
End Module
