比較兩個 TimeSpan 值，回傳一個整數，表示第一個值是比第二個值短、等於還是長。
public:
static int Compare(TimeSpan t1, TimeSpan t2);public static int Compare(TimeSpan t1, TimeSpan t2);static member Compare : TimeSpan * TimeSpan -> intPublic Shared Function Compare (t1 As TimeSpan, t2 As TimeSpan) As Integer參數
- t1
- TimeSpan
第一次比較時間間隔。
- t2
- TimeSpan
第二次比較時間間隔。
傳回
以下其中一項價值。
| 價值 | 描述 |

範例
以下範例使用此 Compare 方法，將多個 TimeSpan 物體與 TimeSpan 一個值為 2 小時時間間隔的物體進行比較。
// 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)
open System
// Define a time interval equal to two hours.
let baseInterval = TimeSpan(2, 0, 0)
// Define a list of time intervals to compare with
// the base interval.
let spans =
[ TimeSpan.FromSeconds -2.5
TimeSpan.FromMinutes 20
TimeSpan.FromHours 1
TimeSpan.FromMinutes 90
baseInterval
TimeSpan.FromDays 0.5
TimeSpan.FromDays 1 ]
// Compare the time intervals.
for span in spans do
let result = TimeSpan.Compare(baseInterval, span)
printfn $"""{baseInterval} {if result = 1 then ">" elif result = 0 then "=" else "<"} {span} (Compare returns {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)
