Users are familiar with the advantages of multithreading, and can make full use of system resources to achieve the maximum value through reasonable scheduling.ProgramBut if it is not properly designed, it will be contrary to the original intention and bring more trouble. This article mainly summarizes and summarizes the "data competition" issue in multi-thread programming, some functions under Win32 are des

You have read all three books. After some experiments, I finally figured out the essence of join. Let's take a look at whether my writing method is easy to understand, whether it really writes the essence of join (), and give more valuable comments.]

When writing remoting programs or other applications, we will inevitably deal with threads ,. net makes it easy to create a thread, but the method provided by it to create a thread and start a thread does not provide obvious parameters, what if we want to use a thread to start a method with parameters in the class?

C # multi-thread Development 7: Use the Monitor class to synchronize multiple threads
In the article "Synchronize multiple threads with the lock statement", use the lock statement to synchronize multiple threads to access critical resources.
The code for using the lock statement is as follows.

In multi-threaded programming, we often need to update the interface display in the working thread. In multithreading, it is wrong to call interface controls directly, invoke and begininvoke occur to solve this problem, so that you can safely update the interface display in multiple threads.
The correct method is to update the interface in the work thread.CodeEncapsulated as a method, called through invok
Multi-thread programming deadlock (c #),
I. Concept of deadlock
If the synchronization of multiple threads is improperly designed, a deadlock may occur. A deadlock is a situation where multiple threads are waiting for the other party to release resources while sharing some resources, resulting in program stagnation.
Deadlocks can lead to program stagnation, so
