Thread. Sleep (0), Thread. Sleep (0) The article I saw was well written.   We may often use the Thread. Sleep function to suspend the Thread for a period of time. Do you understand the usage of this function correctly? Consider the following two

Sleep (n) is used to sleep the current thread for N milliseconds to execute other threads. If there are no other threads, the thread will continue to run after N milliseconds of sleep. If n = 0, sleep (0) means that the CPU hands over the

First, we need to understand the related concepts: 1. CPU usage is actually the CPU resources occupied by the program you run, indicating the running program of your machine at a certain time point. Higher usage High, indicating that your machine

The meaning of Sleep (0) is to discard the current thread execution time slices and put itself in the waiting queue. At this point the other threads will get the time slice to program the program. Sleep (0) can reduce the execution speed of the

The concept of thread can be understood as a small unit in a process. This unit is an independent execution unit, but shares the memory unit in the process with other threads in the process. Because the CPU resources are limited, multiple threads

We may often use the thread. Sleep function to suspend the thread for a period of time. Do you understand the usage of this function correctly? Consider the following two questions:Suppose it is 12:00:00. 000. If I call thread. Sleep (1000), this

Thread. Sleep (0) indicates that the Thread is suspended for 0 milliseconds. You may feel that it is useless. You have to write Thread. Sleep (1000. It seems meaningless. MSDN Description: Specify zero (0) to indicate that this thread should be
