使用 C# 等待外壳应用程序完成

无限期等待外壳应用程序完成

下面的代码示例启动另一个应用程序（本例中是 Notepad），并无限期等待该应用程序关闭。

//How to Wait for a Shelled Process to Finish    //Get the path to the system folder.    string sysFolder=  Environment.GetFolderPath(Environment.SpecialFolder.System);    //Create a new process info structure.    ProcessStartInfo pInfo = new ProcessStartInfo();    //Set the file name member of the process info structure.    pInfo.FileName = sysFolder + @"/eula.txt";    //Start the process.    Process p = Process.Start(pInfo);    //Wait for the window to finish loading.    p.WaitForInputIdle();    //Wait for the process to end.    p.WaitForExit();    MessageBox.Show("Code continuing..."); 

为外壳应用程序设置超时
下面的代码示例为外壳应用程序设置了超时。示例中的超时设置为 5 秒。在测试中您可能希望调整此数字（以毫秒计）。 

//Set a time-out value.    int timeOut=5000;    //Get path to system folder.    string sysFolder=       Environment.GetFolderPath(Environment.SpecialFolder.System);    //Create a new process info structure.    ProcessStartInfo pInfo = new ProcessStartInfo();    //Set file name to open.    pInfo.FileName = sysFolder + @"/eula.txt";    //Start the process.    Process p = Process.Start(pInfo);    //Wait for window to finish loading.    p.WaitForInputIdle();    //Wait for the process to exit or time out.    p.WaitForExit(timeOut);    //Check to see if the process is still running.    if (p.HasExited == false)     //Process is still running.     //Test to see if the process is hung up.     if (p.Responding)           //Process was responding; close the main window.            p.CloseMainWindow();     else         //Process was not responding; force the process to close.    p.Kill();    MessageBox.Show("Code continuing...");
