从桌面应用程序运行Windows 10的相机应用程序

Question

我需要在c＃中运行Windows 10的默认相机应用程序。 我试过不同的方法，如：

process.start("camera.exe"): 
ms-camera:// 
microsoft.windows.camera 

但都失败了。

这不是一个商店应用程序，所以我不能使用“launch URI”方法。

Answer 1

使用此启动相机应用：

Process.Start("microsoft.windows.camera:"); 

Answer 2

相机应用是通用的Windows应用程序，所以你不能简单地执行* .exe文件。使用Nasreddine所示的注册协议或通过IApplicationActivationManager这种方法。

从this answer

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 
{ 
    // 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. 
    IntPtr ActivateApplication([In] String appUserModelId, [In] String arguments, [In] ActivateOptions options, [Out] out UInt32 processId); 
    IntPtr ActivateForFile([In] String appUserModelId, [In] IntPtr /*IShellItemArray* */ itemArray, [In] String verb, [Out] out UInt32 processId); 
    IntPtr ActivateForProtocol([In] String appUserModelId, [In] IntPtr /* IShellItemArray* */itemArray, [Out] out UInt32 processId); 
} 

[ComImport, Guid("45BA127D-10A8-46EA-8AB7-56EA9078943C")]//Application Activation Manager 
class ApplicationActivationManager : IApplicationActivationManager 
{ 
    [MethodImpl(MethodImplOptions.InternalCall, MethodCodeType = MethodCodeType.Runtime)/*, PreserveSig*/] 
    public extern IntPtr ActivateApplication([In] String appUserModelId, [In] String arguments, [In] ActivateOptions options, [Out] out UInt32 processId); 
    [MethodImpl(MethodImplOptions.InternalCall, MethodCodeType = MethodCodeType.Runtime)] 
    public extern IntPtr ActivateForFile([In] String appUserModelId, [In] IntPtr /*IShellItemArray* */ itemArray, [In] String verb, [Out] out UInt32 processId); 
    [MethodImpl(MethodImplOptions.InternalCall, MethodCodeType = MethodCodeType.Runtime)] 
    public extern IntPtr ActivateForProtocol([In] String appUserModelId, [In] IntPtr /* IShellItemArray* */itemArray, [Out] out UInt32 processId); 
} 

使用源代码，然后通过其AppUserModelID Microsoft.WindowsCamera_8wekyb3d8bbwe!App启动相机应用：

private void button3_Click(object sender, EventArgs e) 
{ 
    ApplicationActivationManager appActiveManager = new ApplicationActivationManager(); 
    uint pid; 
    appActiveManager.ActivateApplication("Microsoft.WindowsCamera_8wekyb3d8bbwe!App", null, ActivateOptions.None, out pid); 
}
