2. ManualResetEvent detailed

ManualResetEvent allows threads to communicate with each other by signaling. Typically, this communication involves a task that a thread must complete before other threads are made. When a thread starts an activity (this activity must be completed before other threads can start), it calls Reset to put ManualResetEvent in a non-terminating state, which can be considered a control ManualResetEvent. A thread that calls WaitOne on ManualResetEvent will block and wait for the signal. When the control thread finishes the activity, it calls Set to emit a signal that the waiting thread can continue. And frees all waiting threads. Once it is terminated, ManualResetEvent will remain signaled (that is, the thread of the call to WaitOne will return immediately, not block) until it is manually reset. You can control the initial state of a ManualResetEvent by passing a Boolean value to the constructor, true if the initial state is signaled, or false if it is in the terminating state.
