.Net 4.0 中的 Timeout.InfiniteTimespan? [英] Timeout.InfiniteTimespan in .Net 4.0?

问题描述

我确实知道 Timeout.InfiniteTimespan 在 .NET 4.0 中不存在.

I actually do know that Timeout.InfiniteTimespan does not exist in .NET 4.0.

请注意，.NET 4.0 中也存在 Timeout.Infinite

Noticed, there's also Timeout.Infinite which does exist in .NET 4.0

我正在调用这两个方法:

I am calling those two methods:

// the Change-Method
public bool Change(
    TimeSpan dueTime,
    TimeSpan period
)

// the Constructor of Timer
public Timer(
    TimerCallback callback,
    Object state,
    TimeSpan dueTime,
    TimeSpan period
)

在某些情况下，dueTime 参数需要是无限的，这意味着事件不会被触发.我知道我可以简单地使用其他重载，但我觉得有些事情必须更简单.

in some cases, the dueTime Parameter needs to be infinite, which means the Event is not fired. I know I could simply use an other overload, but I feel like something has to be more simple.

我已经尝试使用 new TimeSpan(0, 0, -1) 或 new TimeSpan(-1) 作为 DueTime.*但这会引发一个 ArgumentOutOfRangeException 指向 dueTime 参数.

I already tried using new TimeSpan(0, 0, -1) or new TimeSpan(-1) as dueTime. *But that throws an ArgumentOutOfRangeException pointing to the dueTime Parameter.

是否有可能创建一个像 .NET 4.5 中的 Timeout.InfiniteTimespan 一样工作的文字?

Is it somehow possible to create a literal working like the Timeout.InfiniteTimespan from .NET 4.5 ?

推荐答案

TimeOut.InfiniteTimeSpan in TimeOut 类定义为:

TimeOut.InfiniteTimeSpan in TimeOut class is defined as:

public static readonly TimeSpan InfiniteTimeSpan = new TimeSpan(0, 0, 0, 0, Timeout.Infinite);

其中 Timeout.Infinite 设置为 -1，因此它正在传递 -1毫秒值 部分.

Where Timeout.Infinite is set to -1,so it is passing -1 value for milliseconds part.

你可以这样做:

TimeSpan InfiniteTimeSpan = new TimeSpan(0, 0, 0, 0, -1);
