任务状态WaitingForActivati​​on - 这是什么意思？ [英] Task status WaitingForActivation - what does this mean?

问题描述

我开始WPF任务，低于

  VAR newTask = Task.Factory.StartNew（（）=>的样子; 
 {
 fcStartSubPageCrawl（srMainSiteURL，srMainSiteId）; 
}。）ContinueWith（（T）=> 
 {
变种aggException = t.Exception.Flatten（） ; 
的foreach（在aggException.InnerExceptions变种除外）
 csPages.LogException（exception.ToString（））; 
}，
 TaskContinuationOptions.OnlyOnFaulted）; 
  

现在当我检查任务状态

这样的（分配到任务列表新任务）：

 如果（tskLocalTask​​List [I] .IsCompleted ==假）
  

我看到那个任务状态= WaitingForActivati​​on

这是什么意思 ？以及为什么它正在等待激活？

C＃4.0 WPF

解决方案

WaitingForActivati​​on是任务所在的启动方法的调用，并在该任务获取任务调度计划的时刻之间的时间。所以直接到任务的启动方法的调用后，任务状态被设置为WaitingForActivati​​on和scheduler.AddWork一个调用。在这里，任务或者是调度器（WaitingToRun）或immidiatly运行。

呵呵，这已无关WPF，任务是BCL

I am starting wpf tasks with the way below

var newTask = Task.Factory.StartNew(() =>
{
fcStartSubPageCrawl(srMainSiteURL, srMainSiteId);
}).ContinueWith((t) =>
{
  var aggException = t.Exception.Flatten();
 foreach (var exception in aggException.InnerExceptions)
   csPages.LogException(exception.ToString());
},
TaskContinuationOptions.OnlyOnFaulted);

Now when i check the task status

like this (new tasks assigned to task list) :

  if (tskLocalTaskList[i].IsCompleted == false)

I am seeing that task status = WaitingForActivation

what does this mean ? And why it is waiting activation ?

C# 4.0 WPF

解决方案

WaitingForActivation is the time the task resides between a call to the Start method and the moment in which the task gets scheduled by the Task scheduler. So directly after a call to the start method of a task, the tasks status is being set to WaitingForActivation and a call to scheduler.AddWork is made. In here, the Task is either scheduler (WaitingToRun) or run immidiatly.

Oh, and this has nothing to do with WPF, Tasks are a part of the BCL
