Write multithreading todayProgramThis error occurs when waitall is used. The reason obtained after searching on the Internet is the difference between [mtathread] and [stathread]. This is a thread model problem, which is probably clear, but it is not very thorough, because the program is relatively large, and it is not willing to modify anything at will. In another thought, why do we have to wait all? Use the following directly: Foreach (var v in

AsyncWaitHandle member, or the WaitAll ()/waitany () method that invokes the task (both methods are in the. In the NET4.0 version, the internal is implemented as a task-based WaitHandle object). This makes it more difficult to answer the question "Should I release a task" because if the
