我为什么要获得互操作服务。尝试从C#启动QTP时发生COM异常?

Can I use a language other than VBScript to programmatically execute QTP Tests?

System.Runtime.InteropServices.COMException 这似乎是由COM对象抛出 RPC_E_SERVERFAULT

virtual public QuickTest.Application LaunchQuickTestPro()
{
    QuickTest.Application qtpApp = new QuickTest.Application();
    qtpApp.Launch();
    qtpApp.Visible = false;
    return qtpApp;
}

qtpApp.Launch();

更新 (没有开发环境),但是 发布版本不

更新2 Main() 方法和我的 ExitQTP()

ref 但是,每次在IDE(SharpDevelop 2.2.1)中运行时,代码都会工作。

    //Program starts here
    [STAThread]
    public static void Main(string[] args)
    {      
        string configFileName = 
            ConfigurationManager.AppSettings.Get("TestPathsConfigFile");

        TextReader configFile = new StreamReader(configFileName);
        QTPLauncher launcher = new QTPLauncher();
        string testName = null; 
        try
        {
            Debug.WriteLine("Creating QuickTest.Application object...");
            QuickTest.Application qtpApp = launcher.LaunchQuickTestPro();
            Debug.WriteLine("Successfully created QuickTest.Application object...");

            while((testName = configFile.ReadLine()) != null)
            {
                if((testName != string.Empty) &&
                   (!(testName.TrimStart()).StartsWith(COMMENT_START)))
                {
                    Debug.WriteLine(testName);

                    launcher.ExecuteQTPTest(testName, ref qtpApp);

                }
            } 

            configFile.Close(); 

           ... //code unrelated to problem removed.

            configFile = null;
            launcher.ExitQTP(ref qtpApp);
        }
        catch(System.Runtime.InteropServices.COMException ce)
        {
            Console.Error.WriteLine(ce.StackTrace);
        }
    }

//Exits QTP
virtual public void ExitQTP(ref QuickTest.Application qtpApp)
{
    qtpApp.Quit();
    qtpApp = null;
}
