Lab+1+进程的创建与终止.doc

Lab 1 进程的创建与终止实验目的：掌握利用程序创建进程和终止进程的基本方法说明：本次实验采用.NET平台提供的Process类实现对本地进程信息的访问，以及启动和停止本地系统进程。1创建进程例1. 创建一个新的进程，这个新的进程是一个记事本程序步骤：1）在代码中引入System.Diagnostics名字空间2）关键代码：var pro = new Process(); pro.StartInfo.FileName = notepad.exe;pro.Start();2.获取计算机运行中的进程信息 / Get the current process.Process currentProcess = Process.GetCurrentProcess();/ Get all instances of Notepad running on the local computer.Process localByName = Process.GetProcessesByName(notepad);/ Get all instances of Notepad running on the specifiec computer./ 1. Using the computer alias (do not precede with ).Process remoteByName = Process.GetProcessesByName(notepad, myComputer);/ 2. Using an IP address to specify the machineName parameter. Process ipByName = Process.GetProcessesByName(notepad, );/ Get all processes running on the local computer.Process localAll = Process.GetProcesses();/ Get all processes running on the remote computer.Process remoteAll = Process.GetProcesses(myComputer);/ Get a process on the local computer, using the process id.Process localById = Process.GetProcessById(1234);/ Get a process on a remote computer, using the process id.Process remoteById = Process.GetProcessById(2345, myComputer);3.终止进程有2个方法：方法1）Process.CloseMainWindow 方法：通过向进程的主窗口发送关闭消息来关闭拥有用户界面的进程。例子：下面的示例启动一个记事本实例。然后它最多在 10 秒内，以两秒为间隔检索关联进程的物理内存使用情况。该示例检测该进程在经过 10 秒后是否退出。如果该进程在 10 秒后仍在运行，该示例就会将其关闭。参考代码：using System;using System.Diagnostics;using System.Threading;namespace Process_Sample class MyProcessClass public static void Main() try Process myProcess; myProcess = Process.Start(Notepad.exe); / Display physical memory usage 5 times at intervals of 2 seconds. for (int i = 0;i 5; i+) if (!myProcess.HasExited) / Discard cached information about the process. myProcess.Refresh(); / Print working set to console. Console.WriteLine(Physical Memory Usage: + myProcess.WorkingSet.ToString(); / Wait 2 seconds. Thread.Sleep(2000); else break; / Close process by sending a close message to its main window. myProcess.CloseMainWindow(); / Free resources associated with process. myProcess.Close(); catch(Exception e) Console.WriteLine(The following exception was raised: ); Console.WriteLine(e.Message); 方法2：Process.Kill:Kill强制终止进程，而CloseMainWindow只是请求终止。参考代码：下面代码是把所有的记事本进程统统枪毙Process pro2Kill = Process.GetProcessesByName(notepad);foreach (Process p in pro2Kill) p.Kill(); foreach (var p in remoteAll) Console.WriteLine(0,1, p.ProcessName, p.Id); int k; Console.WriteLine(请?输?入?结束?进?程id); k=int.Parse(Console.ReadLine(); while (k != 0) var pk = Process.GetProcessById(k); pk.Kill(); remoteAll = Process.GetProcesses(); foreach (var p in remot
