In the previous article, the producers and consumers were implemented with condition, in which the condition await and singal were used, and this implementation was particularly similar to the lock of object, if the lock mechanism of object was used
When we use winform applications, we usually encounter the problem of using the control information on the multi-threaded control interface. However, we cannot use traditional methods to solve this problem. I will introduce it in detail below.
