使用 C# 等待外殼應用程序完成

無限期等待外殼應用程序完成

下面的代碼示例啓動另一個應用程序（本例中是 Notepad），並無限期等待該應用程序關閉。

//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...");

爲外殼應用程序設置超時

下面的代碼示例爲外殼應用程序設置了超時。示例中的超時設置爲 5 秒。在測試中您可能希望調整此數字（以毫秒計）。

//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...");
