However, you should use Task.Run while invoking the task and not inside the implementation of the task. You should use Task.Run primarily on CPU bound methods. The Task.Run method is recommended to use when you don't need to have much fine-grained control over thread scheduling and its intricacies. If you were to use the TaskFactory.StartNew method effectively and reliably, you should use a custom task scheduler and then specify the CancellationToken and TaskCreationOptions. In other words, we should avoid using unless there is a need to create a task scheduler and then pass it explicitly when calling the StartNew method to create a new task and schedule it. I would always recommend using Task.Run as it is much simpler and has safer defaults. If may want to use if you have created a custom task scheduler and pass the scheduler instance to it explicitly. On the contrary, a call to (action) is equivalent to the following statement: (action, CancellationToken.None, TaskCreationOptions.None, TaskScheduler.Current) Note that a call to Task.Run(action) is equivalent to the following statement: (action, CancellationToken.None, TaskCreationOptions.Den圜hildAttach, TaskScheduler.Default) It should be noted that defaults to TaskScheduler.Current and not TaskScheduler.Default. On the contrary, if a scheduler isn't available, it would execute the task on a thread pool thread. Note that if a task scheduler is available, the StartNew method will execute the task on that task scheduler. If you would like to execute synchronous code, is not a good choice. However, it is not recommended to be used for reasons aplenty.
Note that a call to is functionally equivalent to creating a task instance and then calling the Start method on the instance. is a quick way of creating and starting a Task. You can also create tasks using lamba and anonymous methods. Task task1 = new Task (new Action(Display))
Taskfactory as timer code#
The following code snippet shows how you can create tasks using actions and delegates. You can also create tasks using a delegate or an action. String text = await Task.FromResult(GetMessage()) If you would like to return a value from a Task you can take advantage of Task.FromResult method as shown in the code snippet below. While the method works like a fork operation and is used to create and start new tasks, the Wait method works just like a join operation and waits for the task to be complete. This property is used to create and schedule tasks. The Task.Factory property is an instance of the TaskFactory class. While the former is used to create a task that doesn't return a value, the latter is used to create tasks that have return values. You need to make use of the or class to create tasks (a schedulable unit of work). There are several ways in which you can create and start tasks in. How do I create Tasks using the Task Parallel Library?
To build your own custom task scheduler you would need to create a class that extends the class. The default task scheduler will suffice most of the time, but you can also build your own custom task scheduler to provide added functionalities. Net framework thread pool, and there's the task scheduler that executes on the synchronization context of a specified target. There's the default task scheduler that runs on the. Net framework provides you with two task schedulers. If you are working with parallel code, I would say that StartNew is a good choice.Ī task scheduler is a component that is responsible for scheduling tasks The. In most cases, it is advisable to avoid using method if you are working with asynchronous code. When creating tasks using or Task.Run methods, you should keep certain important points in mind when writing asynchronous code.
