3, Process:process-> method: 1. Get the operating system process: Process.getprocess () 2. Start the application: Process.Start ("program name", "File to open"); open Web address: Process.Start ("Iexplore.ext", "htttp://www.baidu.com"); 3. When the program is not a global type, the program name is added to the path. 4, example method:. Thread ();. Kill (); 4, Thread:thread-> properties and methods: Static: 1, thread.sleep (int time milliseconds) = = "Thread stops how many milliseconds 2, thread.currentthread;==> gets the current default main thread. (initial thread) instance: 1, Thread.Start (); marks the start of the thread, waiting for the CPU to execute. 2, Thread. isbackground;=== "marks the new thread as a background thread. 3, Thread. Priority=thread.normal;==> recommends the operating system level for this thread. is not necessarily effective. 4, Thread. The ID of the managerthreadid;==> thread. 5, Thread. Abort ();==> the last resort, so that the thread ends directly. 6, Thread. Join (after int milliseconds);==> waits for thread thread execution to complete ==> This method is executed by the main thread. The thread executing the code waits for the thread to execute after a certain amount of time has been executed. When the time is set too long, the main thread command waits until the current thread ends. When written in a loop, it can be cycled and the start time is the last execution time. -line Cheng The foreground thread, the process exits when all foreground threads exit. The background thread is not blocked. ->main method. The program will default to create a foreground main thread to execute the Main method: 5, cross-thread access issues: 1, close the restriction of cross-thread access: CONTROL.CHECKFORLLEGACROSSTHREADCALLS=FALSE;2, determine whether cross-thread access: Determine the current control. The value of invokerequired, if true, indicates that the control is not created by the current access thread. To call the thread that originally created him for access. Use the control name. Invoke (pass in a delegate to invoke the method you want to access.) ), when false. Execute the access. if (the name of the control. invokerequired) {control name. Invoke (The new action< parameter type passed in > () =>{executed by the party(}else{), the parameter to pass in);//Find the thread that created the control, and execute the delegate method to access the control directly. }
