示例

下面的示例实例化一个表示两个日期之间的差异的 TimeSpan 对象。The following example instantiates a TimeSpan object that represents the difference between two dates. 然后,它显示 TimeSpan 对象的属性。It then displays the TimeSpan object's properties.

// Define two dates.
DateTime date1 = new DateTime(2010, 1, 1, 8, 0, 15);
DateTime date2 = new DateTime(2010, 8, 18, 13, 30, 30);

// Calculate the interval between the two dates.
TimeSpan interval = date2 - date1;
Console.WriteLine("{0} - {1} = {2}", date2, date1, interval.ToString());

// Display individual properties of the resulting TimeSpan object.
Console.WriteLine("   {0,-35} {1,20}", "Value of Days Component:", interval.Days);
Console.WriteLine("   {0,-35} {1,20}", "Total Number of Days:", interval.TotalDays);
Console.WriteLine("   {0,-35} {1,20}", "Value of Hours Component:", interval.Hours);
Console.WriteLine("   {0,-35} {1,20}", "Total Number of Hours:", interval.TotalHours);
Console.WriteLine("   {0,-35} {1,20}", "Value of Minutes Component:", interval.Minutes);
Console.WriteLine("   {0,-35} {1,20}", "Total Number of Minutes:", interval.TotalMinutes);
Console.WriteLine("   {0,-35} {1,20:N0}", "Value of Seconds Component:", interval.Seconds);
Console.WriteLine("   {0,-35} {1,20:N0}", "Total Number of Seconds:", interval.TotalSeconds);
Console.WriteLine("   {0,-35} {1,20:N0}", "Value of Milliseconds Component:", interval.Milliseconds);
Console.WriteLine("   {0,-35} {1,20:N0}", "Total Number of Milliseconds:", interval.TotalMilliseconds);
Console.WriteLine("   {0,-35} {1,20:N0}", "Ticks:", interval.Ticks);

注解

一个 TimeSpan 对象表示时间间隔(时间间隔或运行时间),其测量方式为正值、小时、分钟、秒和秒的小数部分。A TimeSpan object represents a time interval (duration of time or elapsed time) that is measured as a positive or negative number of days, hours, minutes, seconds, and fractions of a second. TimeSpan 结构还可以用于表示一天中的时间,但前提是该时间与特定日期无关。The TimeSpan structure can also be used to represent the time of day, but only if the time is unrelated to a particular date. 否则,应改为使用 DateTimeDateTimeOffset 结构。Otherwise, the DateTime or DateTimeOffset structure should be used instead. (有关使用 TimeSpan 结构来反映当天的时间的详细信息,请参阅在 DateTime、DateTimeOffset、TimeSpan 和 TimeZoneInfo 之间进行选择。)(For more information about using the TimeSpan structure to reflect the time of day, see Choosing Between DateTime, DateTimeOffset, TimeSpan, and TimeZoneInfo.)

备注

TimeSpan 值表示时间间隔,可表示为特定的天数、小时数、分钟数、秒数和毫秒数。A TimeSpan value represents a time interval and can be expressed as a particular number of days, hours, minutes, seconds, and milliseconds. 因为它表示不引用特定开始点或结束点的常规间隔,所以不能用年份和月份来表示,这两种间隔的天数都是可变的。Because it represents a general interval without reference to a particular start or end point, it cannot be expressed in terms of years and months, both of which have a variable number of days. 它与 DateTime 值不同,后者表示不引用特定时区的日期和时间,或表示特定时间段的 DateTimeOffset 值。It differs from a DateTime value, which represents a date and time without reference to a particular time zone, or a DateTimeOffset value, which represents a specific moment of time.

TimeSpan 结构用来度量持续时间的最大时间单位是一天。The largest unit of time that the TimeSpan structure uses to measure duration is a day. 时间间隔以天为单位进行一致性度量,因为较大的时间单位(如月份和年份)的天数会变化。Time intervals are measured in days for consistency, because the number of days in larger units of time, such as months and years, varies.

TimeSpan 对象的值是与所表示的时间间隔相等的计时周期数。The value of a TimeSpan object is the number of ticks that equal the represented time interval. 勾选标记等于100毫微秒,即 1 10-秒秒。A tick is equal to 100 nanoseconds, or one ten-millionth of a second. TimeSpan 对象的值的范围可以是 TimeSpan.MaxValueTimeSpan.MinValueThe value of a TimeSpan object can range from TimeSpan.MinValue to TimeSpan.MaxValue.

实例化 TimeSpan 值Instantiating a TimeSpan Value

可以通过多种方式实例化 TimeSpan 值:You can instantiate a TimeSpan value in a number of ways:

  • 通过调用其隐式无参数构造函数。By calling its implicit parameterless constructor. 这会创建一个对象,其值为 TimeSpan.Zero,如下面的示例所示。This creates an object whose value is TimeSpan.Zero, as the following example shows.

    TimeSpan interval = new TimeSpan();
    Console.WriteLine(interval.Equals(TimeSpan.Zero));    // Displays "True".
    
    Dim interval As New TimeSpan()
    Console.WriteLine(interval.Equals(TimeSpan.Zero))     ' Displays "True".
    
  • 通过调用其显式构造函数之一。By calling one of its explicit constructors. 下面的示例将 TimeSpan 值初始化为指定的小时数、分钟数和秒数。The following example initializes a TimeSpan value to a specified number of hours, minutes, and seconds.

    TimeSpan interval = new TimeSpan(2, 14, 18);
    Console.WriteLine(interval.ToString());              
    
    // Displays "02:14:18".
    
    Dim interval As New TimeSpan(2, 14, 18)
    Console.WriteLine(interval.ToString())                ' Displays "02:14:18".
    
  • 通过调用方法或执行返回 TimeSpan 值的操作。By calling a method or performing an operation that returns a TimeSpan value. 例如,可以实例化一个表示两个日期和时间值之间的间隔的 TimeSpan 值,如下例所示。For example, you can instantiate a TimeSpan value that represents the interval between two date and time values, as the following example shows.

    DateTime departure = new DateTime(2010, 6, 12, 18, 32, 0);
    DateTime arrival = new DateTime(2010, 6, 13, 22, 47, 0);
    TimeSpan travelTime = arrival - departure;  
    Console.WriteLine("{0} - {1} = {2}", arrival, departure, travelTime);      
    
    // The example displays the following output:
    //       6/13/2010 10:47:00 PM - 6/12/2010 6:32:00 PM = 1.04:15:00
    
    Dim departure As DateTime = #06/12/2010 6:32PM#
    Dim arrival As DateTime = #06/13/2010 10:47PM#
    Dim travelTime As TimeSpan = arrival - departure  
    Console.WriteLine("{0} - {1} = {2}", arrival, departure, travelTime)      
    ' The example displays the following output:
    '       6/13/2010 10:47:00 PM - 6/12/2010 6:32:00 PM = 1.04:15:00
    

    您还可以通过这种方式将 TimeSpan 对象初始化为零时间值,如下面的示例所示。You can also initialize a TimeSpan object to a zero time value in this way, as the following example shows.

       Random rnd = new Random();
    
       TimeSpan timeSpent = TimeSpan.Zero;
    
       timeSpent += GetTimeBeforeLunch();
       timeSpent += GetTimeAfterLunch();
    
       Console.WriteLine("Total time: {0}", timeSpent);
    
       TimeSpan GetTimeBeforeLunch()
       {
          return new TimeSpan(rnd.Next(3, 6), 0, 0);
       }
       
       TimeSpan GetTimeAfterLunch()
       {
          return new TimeSpan(rnd.Next(3, 6), 0, 0);
       }
    
       // The example displays output like the following:
       //        Total time: 08:00:00
    
    Module Example
       Dim rnd As New Random()
       
       Public Sub Main()
          Dim timeSpent As TimeSpan = TimeSpan.Zero
    
          timeSpent += GetTimeBeforeLunch()
          timeSpent += GetTimeAfterLunch()
    
          Console.WriteLine("Total time: {0}", timeSpent)
       End Sub
       
       Private Function GetTimeBeforeLunch() As TimeSpan
          Return New TimeSpan(rnd.Next(3, 6), 0, 0)
       End Function
       
       Private Function GetTimeAfterLunch() As TimeSpan
          Return New TimeSpan(rnd.Next(3, 6), 0, 0)
       End Function
    End Module
    ' The example displays output like the following:
    '       Total time: 08:00:00
    

    TimeSpan 值由 DateTimeDateTimeOffsetTimeSpan 结构的算术运算符和方法返回。TimeSpan values are returned by arithmetic operators and methods of the DateTime, DateTimeOffset, and TimeSpan structures.

  • 通过分析 TimeSpan 值的字符串表示形式。By parsing the string representation of a TimeSpan value. 您可以使用 ParseTryParse 方法将包含时间间隔的字符串转换为 TimeSpan 值。You can use the Parse and TryParse methods to convert strings that contain time intervals to TimeSpan values. 下面的示例使用 Parse 方法将字符串数组转换为 TimeSpan 值。The following example uses the Parse method to convert an array of strings to TimeSpan values.

    string[] values = { "12", "31.", "5.8:32:16", "12:12:15.95", ".12"};
    foreach (string value in values)
    {
       try {
          TimeSpan ts = TimeSpan.Parse(value);
          Console.WriteLine("'{0}' --> {1}", value, ts);
       }
       catch (FormatException) {
          Console.WriteLine("Unable to parse '{0}'", value);
       }
       catch (OverflowException) {
          Console.WriteLine("'{0}' is outside the range of a TimeSpan.", value);
       }   
    }
    
    // The example displays the following output:
    //       '12' --> 12.00:00:00
    //       Unable to parse '31.'
    //       '5.8:32:16' --> 5.08:32:16
    //       '12:12:15.95' --> 12:12:15.9500000
    //       Unable to parse '.12'  
    
    Dim values() As String = { "12", "31.", "5.8:32:16", "12:12:15.95", ".12"}
    For Each value As String In values
       Try
          Dim ts As TimeSpan = TimeSpan.Parse(value)
          Console.WriteLine("'{0}' --> {1}", value, ts)
       Catch e As FormatException
          Console.WriteLine("Unable to parse '{0}'", value)
       Catch e As OverflowException
          Console.WriteLine("'{0}' is outside the range of a TimeSpan.", value)
       End Try   
    Next
    ' The example displays the following output:
    '       '12' --> 12.00:00:00
    '       Unable to parse '31.'
    '       '5.8:32:16' --> 5.08:32:16
    '       '12:12:15.95' --> 12:12:15.9500000
    '       Unable to parse '.12'  
    

    此外,还可以通过调用 ParseExactTryParseExact 方法,定义要分析并转换为 TimeSpan 值的输入字符串的精确格式。In addition, you can define the precise format of the input string to be parsed and converted to a TimeSpan value by calling the ParseExact or TryParseExact method.

对 TimeSpan 值执行操作Performing Operations on TimeSpan Values

您可以通过使用 AdditionSubtraction 运算符或通过调用 AddSubtract 方法来增加和减少持续时间。You can add and subtract time durations either by using the Addition and Subtraction operators, or by calling the Add and Subtract methods. 还可以通过调用 CompareCompareToEquals 方法来比较两个持续时间。You can also compare two time durations by calling the Compare, CompareTo, and Equals methods. TimeSpan 结构还包括 DurationNegate 方法,将时间间隔转换为正值和负值,The TimeSpan structure also includes the Duration and Negate methods, which convert time intervals to positive and negative values,

TimeSpan 值的范围将 MinValue MaxValueThe range of TimeSpan values is MinValue to MaxValue.

设置 TimeSpan 值的格式Formatting a TimeSpan Value

TimeSpan 值可以表示为 [-]dhhmmssff,其中可选的负号指示负时间间隔, d组件是天, hh是小时,以24小时制度量, mm为分钟, ss表示秒,而ff表示为秒的小数部分。A TimeSpan value can be represented as [-]d.hh:mm:ss.ff, where the optional minus sign indicates a negative time interval, the d component is days, hh is hours as measured on a 24-hour clock, mm is minutes, ss is seconds, and ff is fractions of a second. 也就是说,时间间隔由正数或负数,而不是一天中的某个时间或一天中的某个时间或一天中的某个时间。That is, a time interval consists of a positive or negative number of days without a time of day, or a number of days with a time of day, or only a time of day.

.NET Framework 4.NET Framework 4开始,TimeSpan 结构通过其 ToString 方法的重载支持区分区域性的格式设置,这会将 TimeSpan 值转换为其字符串表示形式。Beginning with the .NET Framework 4.NET Framework 4, the TimeSpan structure supports culture-sensitive formatting through the overloads of its ToString method, which converts a TimeSpan value to its string representation. 默认 TimeSpan.ToString() 方法通过使用与先前版本的 .NET Framework 中的返回值相同的固定格式返回时间间隔。The default TimeSpan.ToString() method returns a time interval by using an invariant format that is identical to its return value in previous versions of the .NET Framework. TimeSpan.ToString(String) 重载允许您指定定义时间间隔的字符串表示形式的格式字符串。The TimeSpan.ToString(String) overload lets you specify a format string that defines the string representation of the time interval. TimeSpan.ToString(String, IFormatProvider) 重载使你可以指定格式字符串和用于创建时间间隔的字符串表示形式的格式设置约定的区域性。The TimeSpan.ToString(String, IFormatProvider) overload lets you specify a format string and the culture whose formatting conventions are used to create the string representation of the time interval. TimeSpan 支持标准和自定义格式字符串。TimeSpan supports both standard and custom format strings. (有关详细信息,请参阅标准 Timespan 格式字符串自定义的 timespan 格式字符串。)但是,只有标准格式字符串区分区域性。(For more information, see Standard TimeSpan Format Strings and Custom TimeSpan Format Strings.) However, only standard format strings are culture-sensitive.

还原旧的 TimeSpan 格式Restoring Legacy TimeSpan Formatting

在某些情况下,.NET Framework 4.NET Framework 4不会在 .NET Framework 3.5.NET Framework 3.5 和更早版本中成功设置 TimeSpan 值格式的代码。In some cases, code that successfully formats TimeSpan values in .NET Framework 3.5.NET Framework 3.5 and earlier versions fails in .NET Framework 4.NET Framework 4. 这在调用< TimeSpan_LegacyFormatMode > 元素方法以便使用格式字符串设置 TimeSpan 值格式的代码中最常见。This is most common in code that calls a <TimeSpan_LegacyFormatMode> element method to format a TimeSpan value with a format string. 下面的示例成功设置了 .NET Framework 3.5.NET Framework 3.5 和更早版本中 TimeSpan 值的格式,但在 .NET Framework 4.NET Framework 4 和更高版本中引发了异常。The following example successfully formats a TimeSpan value in .NET Framework 3.5.NET Framework 3.5 and earlier versions, but throws an exception in .NET Framework 4.NET Framework 4 and later versions. 请注意,它尝试使用不受支持的格式说明符(在 .NET Framework 3.5.NET Framework 3.5 及更早版本中被忽略)来设置 TimeSpan 值的格式。Note that it attempts to format a TimeSpan value by using an unsupported format specifier, which is ignored in .NET Framework 3.5.NET Framework 3.5 and earlier versions.

Console.WriteLine("---");

ShowParsingCode();
// Output:

{
   TimeSpan interval = new TimeSpan(12, 30, 45);
   string output;
   try {
      output = String.Format("{0:r}", interval);
   }
   catch (FormatException) {
      output = "Invalid Format";
   }
   Console.WriteLine(output);
}

void ShowParsingCode()
{
   string value = "000000006";
   try {
      TimeSpan interval = TimeSpan.Parse(value);
      Console.WriteLine("{0} --> {1}", value, interval);
   }
   catch (FormatException) {
      Console.WriteLine("{0}: Bad Format", value);
   }   
   catch (OverflowException) {
      Console.WriteLine("{0}: Overflow", value);
   }
}
Dim interval As New TimeSpan(12, 30, 45)
Dim output As String
Try
   output = String.Format("{0:r}", interval)
Catch e As FormatException
   output = "Invalid Format"
End Try
Console.WriteLine(output)
' Output from .NET Framework 3.5 and earlier versions:
'       12:30:45
' Output from .NET Framework 4:
'       Invalid Format

如果无法修改代码,可以通过以下方式之一还原 TimeSpan 值的旧格式设置:If you cannot modify the code, you can restore the legacy formatting of TimeSpan values in one of the following ways:

  • 通过创建包含> 元素 < TimeSpan_LegacyFormatMode的配置文件。By creating a configuration file that contains the <TimeSpan_LegacyFormatMode> element. 将此元素的 enabled 属性设置为 true 会按应用程序还原旧 TimeSpan 格式。Setting this element's enabled attribute to true restores legacy TimeSpan formatting on a per-application basis.

  • 在创建应用程序域时设置 "NetFx40_TimeSpanLegacyFormatMode" 兼容性开关。By setting the "NetFx40_TimeSpanLegacyFormatMode" compatibility switch when you create an application domain. 这将在每个应用程序域的基础上启用旧 TimeSpan 格式设置。This enables legacy TimeSpan formatting on a per-application-domain basis. 下面的示例创建一个使用旧 TimeSpan 格式的应用程序域。The following example creates an application domain that uses legacy TimeSpan formatting.

    using System;
    
    public class Example
    {
       public static void Main()
       {
          AppDomainSetup appSetup = new AppDomainSetup();
          appSetup.SetCompatibilitySwitches( new string[] { "NetFx40_TimeSpanLegacyFormatMode" } );
          AppDomain legacyDomain = AppDomain.CreateDomain("legacyDomain", 
                                                          null, appSetup);
          legacyDomain.ExecuteAssembly("ShowTimeSpan.exe");
       }
    }
    
    Module Example
       Public Sub Main()
          Dim appSetup As New AppDomainSetup()
          appSetup.SetCompatibilitySwitches( { "NetFx40_TimeSpanLegacyFormatMode" } )
          Dim legacyDomain As AppDomain = AppDomain.CreateDomain("legacyDomain", 
                                                                 Nothing, appSetup)
          legacyDomain.ExecuteAssembly("ShowTimeSpan.exe")
       End Sub
    End Module
    

    当在新应用程序域中执行以下代码时,它将恢复为旧 TimeSpan 格式设置行为。When the following code executes in the new application domain, it reverts to legacy TimeSpan formatting behavior.

    using System;
    
    public class Example
    {
       public static void Main()
       {
          TimeSpan interval = DateTime.Now - DateTime.Now.Date;
          string msg = String.Format("Elapsed Time Today: {0:d} hours.",
                                     interval);
          Console.WriteLine(msg);
       }
    }
    // The example displays the following output:
    //       Elapsed Time Today: 01:40:52.2524662 hours.
    
    Module Example
       Public Sub Main()
          Dim interval As TimeSpan = Date.Now - Date.Now.Date
          Dim msg As String = String.Format("Elapsed Time Today: {0:d} hours.",
                                             interval)
          Console.WriteLine(msg)
       End Sub
    End Module
    ' The example displays output like the following:
    '       Elapsed Time Today: 01:40:52.2524662 hours.
