silverlight目前开发的应用,想做到系统内注销后自动重新启动下 sllauncher.exe ,实现方式是通过WMI的COM接口,获取到当前应用的执行命令行(CommandLine);并通过shell运行;代码如下:
#region Using Section using System; using System.Collections.Generic; using System.Runtime.InteropServices.Automation; using System.Windows; #endregion namespace KillSelf { public class ComObjectHelper { private static List<string> GetProcess() { var result = new List<string>(); try { dynamic objLocator = AutomationFactory.CreateObject("WbemScripting.SWbemLocator"); dynamic objWmiService = objLocator.ConnectServer(".", "root\\cimv2"); dynamic query = objWmiService.ExecQuery("Select * from Win32_Process"); foreach (dynamic o in query) { //string value = "ExecutablePath = " + o.CommandLine + "\r\n"; //Console.WriteLine(value); result.Add(o.CommandLine + ""); } return result; } catch (Exception ex) { MessageBox.Show("Get Process:" + ex.Message); } return null; } internal static void Exec(string cmdline) { try { dynamic cmd = AutomationFactory.CreateObject("WScript.Shell"); cmd.Run(cmdline, 1, false); } catch (Exception ex) { MessageBox.Show("Execute Process:" + ex.Message); } } public static SlProcess GetSelf() { string[] procs = GetProcess().ToArray(); foreach (string p in procs) { string cmdline = p.ToLower(); if (cmdline.IndexOf("sllauncher.exe", StringComparison.Ordinal) != -1) { return new SlProcess(cmdline); } } throw new NullReferenceException("未找到SLLauncher.exe进程"); } } public class SlProcess { public SlProcess(string cmdline) { CommandLine = cmdline; } public string CommandLine { get; set; } public SlProcess Run() { ComObjectHelper.Exec(CommandLine); return this; } public SlProcess Kill() { Application.Current.MainWindow.Close(); return this; } } }
