C#中的IApplicationActivationManager::ActivateApplication是什么？

c#comwindows-8
23
我正在为Metro应用程序进行自动化测试，我找到了一些需要的代码，但它是用C++编写的：http://blogs.msdn.com/b/windowsappdev/archive/2012/09/04/automating-the-testing-of-windows-8-apps.aspx 我的问题是，如何在C#中使用IApplicationActivationManager::ActivateApplication，因为我不会C++？ 该方法的详细信息可以在这里找到：http://msdn.microsoft.com/en-us/library/windows/desktop/hh706903(v=vs.85).aspx 这里是我从Shobjidl.idl中提取的代码：
cpp_quote("DEFINE_ENUM_FLAG_OPERATORS(ACTIVATEOPTIONS)")

// IApplicationActivationManger is used to activate an immersive application identified by its Application User Model Id.
//
// Developers who are interested in using the Application Activation Manager do not need to implement the following
// interface. An implementation is provided through the CoCreatable Object with CLSID_ApplicationActivationManager.

    object,
    uuid(2e941141-7f97-4756-ba1d-9decde894a3d),
    pointer_default(unique)
]
interface IApplicationActivationManager : IUnknown
{
    // Activates the specified immersive application for the "Launch" contract, passing the provided arguments
    // string into the application.  Callers can obtain the process Id of the application instance fulfilling this contract.
    HRESULT ActivateApplication(
        [in] LPCWSTR appUserModelId,
        [in, unique] LPCWSTR arguments,
        [in] ACTIVATEOPTIONS options,
        [out] DWORD *processId);
    HRESULT ActivateForFile(
        [in] LPCWSTR appUserModelId,
        [in] IShellItemArray *itemArray,
        [in, unique] LPCWSTR verb,
        [out] DWORD *processId);
    HRESULT ActivateForProtocol(
        [in] LPCWSTR appUserModelId,
        [in] IShellItemArray *itemArray,
        [out] DWORD *processId);
}



// CLSID_ApplicationActivationManager
    [ uuid(45BA127D-10A8-46EA-8AB7-56EA9078943C) ] coclass ApplicationActivationManager { interface IApplicationActivationManager; }
任何想法吗？ 谢谢。

它们实际上是相同的；你只需要将接口声明翻译成C#即可。 - James McNellis

试用下面的代码片段，它对我有效。

public enum ActivateOptions
{
    None = 0x00000000,  // No flags set
    DesignMode = 0x00000001,  // The application is being activated for design mode, and thus will not be able to
    // to create an immersive window. Window creation must be done by design tools which
    // load the necessary components by communicating with a designer-specified service on
    // the site chain established on the activation manager.  The splash screen normally
    // shown when an application is activated will also not appear.  Most activations
    // will not use this flag.
    NoErrorUI = 0x00000002,  // Do not show an error dialog if the app fails to activate.                                
    NoSplashScreen = 0x00000004,  // Do not show the splash screen when activating the app.
}

[ComImport, Guid("2e941141-7f97-4756-ba1d-9decde894a3d"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
interface IApplicationActivationManager

希望你已经知道如何获取应用程序名称以激活。然而，我想在这里分享这个信息，给那些可能搜索相同内容的人。我们可以从下面的注册表位置获得 AppUserModelID： Windows Registry Editor

这是sankar答案的更新版本（非常感谢他，真的帮了我很多），针对ActivateForFile方法。我将itemArray更改为IShellItemArray而不是IntPtr，并添加了来自shell32的接口和方法。
public enum ActivateOptions
{
    None = 0x00000000,  // No flags set
    DesignMode = 0x00000001,  // The application is being activated for design mode, and thus will not be able to
    // to create an immersive window. Window creation must be done by design tools which
    // load the necessary components by communicating with a designer-specified service on
    // the site chain established on the activation manager.  The splash screen normally
    // shown when an application is activated will also not appear.  Most activations
    // will not use this flag.
    NoErrorUI = 0x00000002,  // Do not show an error dialog if the app fails to activate.                                
    NoSplashScreen = 0x00000004,  // Do not show the splash screen when activating the app.
