C #: asynchronous programming and thread usage (. NET 4.5)

C #: asynchronous programming and thread usage (. NET 4.5) Asynchronous programming and thread processing are important features of concurrent or parallel programming. To implement asynchronous programming, you can use threads or not. Speaking of Asynchronization and thread at the same time will help us better understa

C # Multi-Threading vs. asynchronous invocation

The nature of asynchronous operationsSpecifies a callback function for the Async method before the method call, which is executed by a thread in the thread pool after the method call. The main thread returns immediately, continuing to perform other work or responding to user requests. If the Async method finishes executing, the callback function is automatically executed to handle the invocation result of the asyn

Example of asynchronous invocation of C # Basics Tutorial

In this paper, the method of asynchronous invocation in C # is presented, and the principle of it is analyzed in depth, which is now shared by the tutorial for everyone's reference.
