问题 This question already has answers here : Captured variable in a loop in C# (9 answers) Closed 12 days ago . I'm trying to use TPL inside a while loop and I need to pass to the task some values that then changes into the loop. For instance, here it is shown an example with an index that is incremented (necessarily after the line in which the task creation is requested): int index = 0; Task[] tasks; while(/*condition*/) { tasks[index] = Task.Factory.StartNew(() => DoJob(index)); index++; } But

问题 With cyclic or repetitive tasks in org-mode, inside this task, if there are several checkboxes and all of them marked as ticked, after the general task is masked as DONE, the checkboxes for the next cycle period stills appear as ticked and it should be unticked. e.g.: TODO Cyclic monthly home [0/5] SCHEDULED: <2013-11-30 Sat +1m> [ ] pay sauna [ ] pay electricity [ ] pay renting [ ] pay internet [ ] pay union Once I ticked all of them and put it as done, this is what I can see: WIP Cyclic

问题 This works great: private void MainMethod() { Task<bool> taskItemFound = new Task<bool>(ItemFound); } private bool ItemFound() { //Do Work return true; } This works but is UGLY and I can't pass more than one parameter: private void MainMethod() { var startNew = Task<bool>.Factory.StartNew(TempMethod, "cow"); } private bool TempMethod(object o) { return ("holy " + o == "holy cow"); } I'm looking for a solution that will give me a Task<bool> from an existing method with more than one input

I have setup the following: Enabled my app with the Background Modes capability, a checking the "Background fetch". Added my background Id to Info.plist under "Permitted background task
