Chapter 1.3 C# – Tasks
Tasks are bits of code that do things and then waits for things to happen.
so we can have a few methods that can be created and then called to run as a task.
Task newTask = Task.Run(() -> DoWork());
newTask.Wait();
This will create a new task and allow it to run to completion
Return a value from a task.
use the result code to get a return value from the function
static void Main(string[] args)
{
Task<int> task = Task.Run(() =>
{
return DoWork());
});
Console.WriteLine(task.Result);
}
Wait for Tasks to complete
The Task.
Task [] Tasks = new Task[10];
for (int i = 0; i < 10; i++)
{
int taskNum = i;
Tasks[i] = Task.Run( () => DoWork(taskNum) );
}
Task.WaitAll(Tasks);
}
Task.Waitall is to provide a place where a program can catch any exceptions that might be thrown by tasks.
