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

定义

比较两个 TimeSpan 值,并返回一个整数,该整数指示第一个值是短于、等于还是长于第二个值。Compares two TimeSpan values and returns an integer that indicates whether the first value is shorter than, equal to, or longer than the second value.

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

要比较的第一个时间间隔。The first time interval to compare.

t2
TimeSpan TimeSpan TimeSpan TimeSpan

要比较的第二个时间间隔。The second time interval to compare.

返回

以下值之一。One of the following values.

Value 说明Description
-1-1 t1 短于 t2t1 is shorter than t2.
00 t1 等于 t2t1 is equal to t2.
11 t1 长于 t2t1 is longer than t2.

示例

下面的示例使用Compare方法将多个TimeSpan对象与TimeSpan值为2小时时间间隔的对象进行比较。The following example uses the Compare method to compare several TimeSpan objects with a TimeSpan object whose value is a 2-hour time interval.

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
