# TimeSpan.Compare(TimeSpan, TimeSpan)TimeSpan.Compare(TimeSpan, TimeSpan)TimeSpan.Compare(TimeSpan, TimeSpan)TimeSpan.Compare(TimeSpan, TimeSpan) Method

## 定义

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

#### 参数

t1
TimeSpan TimeSpan TimeSpan TimeSpan

t2
TimeSpan TimeSpan TimeSpan TimeSpan

#### 返回

Value 说明Description
-1-1 `t1` 短于 `t2``t1` is shorter than `t2`.
00 `t1` 等于 `t2``t1` is equal to `t2`.
11 `t1` 长于 `t2``t1` is longer than `t2`.

## 示例

``````using System;

class Example
{
static void Main()
{
// 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 return
//       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
