In the process of using C #, it is unavoidable to use multi-threading, and after multithreading, how the thread interacts with the interface is a very headache. In fact, not only the interface, in general, we often need to get some information about the thread to determine the state of the thread. The better way is to use the delegate implementation, see Example:Class TestClass { //declares a delegate (delegate) type: Testdelegate, which can carry a method with a null return value and o

I. OverviewEach system is wired (at least one main thread), and the most important role of threads is parallel processing, which increases the concurrency rate of the software. For the interface, it can also improve the response ability of the interface. In general, for application stability, time-consuming operations such as data processing will run separately in one thread, and all control data refreshes related to the main UI thread should be processed in the main UI thread. That is, the data
