任务中用作Func参数的静态或非静态方法 <TResult> C＃中的构造函数？

Question

I am writing a set of classes all derived from a base class. I want to be able to run multiple Task threads. Can the Func() used in the constructor of the Task be an instance method or does it have to be a class static method? If it is an instance method, can multiple Tasks be started using the same non-static method?

Answer 1

You seem to be conflating static and non static methods with thread safety , for lack of a better term... thread safety is probably as imprecise as a term can be, but it'll work in the present context. This is the completely wrong thing to ask, so unlearn whatever you think you know about the supposedly inbred safety of static members.

The rule is that what you are asking is safe(+) as long as its safe to call that same method concurrently. When is this safe? Well, in broad terms, when the method only writes or reads local variables, only reads immutable shared data or there is some sort of synchronization implemented that allows it to read and/or write concurrently to shared data.

(+) Understand safe as the condition where your code will do what you expect it to do.
