TimeSpan 结构

表示一个时间间隔。

命名空间: System
程序集: mscorlib(在 mscorlib.dll 中)

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
public struct TimeSpan : IComparable, IComparable<TimeSpan>, 
	IEquatable<TimeSpan>
/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
public final class TimeSpan extends ValueType implements IComparable, IComparable<TimeSpan>, 
	IEquatable<TimeSpan>
不适用。

TimeSpan 对象表示时间间隔或持续时间,按正负天数、小时数、分钟数、秒数以及秒的小数部分进行度量。用于度量持续时间的最大时间单位是天。更大的时间单位(如月和年)的天数不同,因此为保持一致性,时间间隔以天为单位来度量。

TimeSpan 对象的值是等于所表示时间间隔的刻度数。一个刻度等于 100 纳秒,TimeSpan 对象的值的范围在 MinValueMaxValue 之间。

TimeSpan 值可以表示为 [-]d.hh:mm:ss.ff,其中减号是可选的,它指示负时间间隔,d 分量表示天,hh 表示小时(24 小时制),mm 表示分钟,ss 表示秒,而 ff 为秒的小数部分。即,时间间隔包括整的正负天数、天数和剩余的不足一天的时长,或者只包含不足一天的时长。例如,初始化为 1.0e+13 刻度的 TimeSpan 对象的文本表示“11.13:46:40”,即 11 天,13 小时,46 分钟和 40 秒。

TimeSpan 类型实现了 System.IComparableSystem.IComparable 接口。

下面的代码示例创建几个 TimeSpan 对象并显示每个对象的属性。

    const string headerFmt = "\n{0,-45}";
