在MSI安装期间重新启动Explorer.exe不起作用

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了在MSI安装期间重新启动Explorer.exe不起作用相关的知识，希望对你有一定的参考价值。
我有一个Visual Studio安装项目，它创建一个MSI来安装我的应用程序。我的应用程序有一个带有图标覆盖处理程序的shell扩展，因此需要重新启动explorer.exe才能使图标覆盖处理程序开始工作。我已经注册了一个自定义操作，以便在使用以下方法重新启动资源管理器的提交上运行：
public static void restartExplorer()
{
//stop the shell
try
{
Process process1 = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "CMD.exe";
startInfo.Arguments = "/C "taskkill /f /im explorer.exe"";
process1.StartInfo = startInfo;
process1.Start();
do
{
Thread.Sleep(100);
if (process1.HasExited)
{
break;
}
} while (true);
}
catch (Exception e)
{
Log.Error("restart explorer", e.StackTrace);
}
//restart the shell
string explorer = string.Format("{0}\{1}", Environment.GetEnvironmentVariable("WINDIR"), "explorer.exe");
Process process = new Process();
process.StartInfo.FileName = explorer;
process.StartInfo.UseShellExecute = true;
process.Start();
}
当我从visual studio测试并从命令行调用它时，此方法很有效，但是在安装或卸载期间从MSI调用它时，它会停止资源管理器，但不会重新启动它。
有没有人知道为什么它会在所有情况下都有效，除非在安装或卸载期间由MSI调用？
有没有人有另一种方法在安装/卸载期间从MSI重新启动资源管理器？
答案
杀死探险家有点粗糙...我建议你使用Restart Manager API。好处是资源管理器知道如何重新启动它，它将在重新启动后恢复所有打开的窗口。这是一个C＃实用程序类，它将为您完成。只需在自定义操作中调用此方法：
...
var rm = new RestartManager();
rm.RestartExplorerProcesses();
