TimeSpan.Compare(TimeSpan, TimeSpan) 方法

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。

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

要比较的第一个时间间隔。

t2
TimeSpan

要比较的第二个时间间隔。

返回

Int32

以下值之一。

“值” 说明
-1 t1 短于 t2
0 t1 等于 t2
1 t1 长于 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。

// 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)

        ' Compare the time intervals.
        For Each span In spans
           Dim result As Integer = TimeSpan.Compare(baseInterval, span)
