以编程方式获取已安装的应用程序可执行文件(Windows10,C#)的列表

我想获取Windows 10上已安装且可执行的应用程序列表,即用户可以启动的应用程序的可执行文件(UWP和非UWP)。对于UWP应用,我想获取其AppUserModelId。对于非UWP应用,我想获取可执行文件的文件位置。

到目前为止,我已经尝试过: 1)遍历注册表并遍历installed applications。但是,此方法会遍历所有已安装的应用程序,返回的列表将包含microsoft asp.net core 2.1.8 shared framework (x64)之类的东西,我想消除它。

2)我发现可以通过在浏览器窗口或“运行”中键入shell:Appsfolder来通过特殊的Appsfolder访问所需的内容。到目前为止,我已经能够访问该文件夹,并遍历所有项目并列出文件名。但是我不确定如何收集有关AppUserModelId(对于UWP应用程序)和文件路径(对于WPF应用程序)的信息。

我用来枚举Appsfolder文件的相关代码:

namespace AppsFolder
{
    ...
    public static class AppsFolder
    {
       ...

       // GUID for shell:Appsfolder
       public static readonly Guid KnownFolderID = new Guid("1e87508d-89c2-42f0-8a7e-645a0f50ca58");

       public static IEnumerable<string> GetItemNames(ESHGDN gdn)
       {
           IShellFolder appsFolder = GetAppsFolder();
           try
           {
               IntPtr enumIDListInterfacePointer;
               appsFolder.EnumObjects(IntPtr.Zero,
                    ESHCONTF.SHCONTF_NONFOLDERS | ESHCONTF.SHCONTF_FOLDERS,
                   out enumIDListInterfacePointer);
               using (var enumIDList = new
                      EnumIDListWrapper(enumIDListInterfacePointer))
               {
                  var names = new List<string>();
                  foreach (var pidl in enumIDList)
                  {
                      STRRET name;
                      recycleBin.GetDisplayNameOf(
                              pidl.DangerousGetHandle(),
                             gdn,
                             out name);
                      names.Add(STRRETToString(ref name, pidl));
                      if (name.uType != (int)STRRETType.Offset)
                         Marshal.FreeCoTaskMem(name.data.pOleStr);
                  }
                  return names;
               }
           }
           finally
           {
               Marshal.FinalReleaseComObject(recycleBin);
           }
        }

        private static IShellFolder GetAppsFolder()
        {
            IShellFolder desktop;
            NativeMethod.SHGetDesktopFolder(out desktop);
            try
            {
                Guid shellFolderInterfaceId = typeof(IShellFolder).GUID;
                IntPtr recycleBinShellFolderInterfacePointer;
                desktop.BindToObject(
                    GetItemIDList().DangerousGetHandle(),
                    IntPtr.Zero,
                    ref shellFolderInterfaceId,
                    out recycleBinShellFolderInterfacePointer);
                return (IShellFolder)Marshal.GetObjectForIUnknown(
                             recycleBinShellFolderInterfacePointer);
            }
            finally
            {
                Marshal.FinalReleaseComObject(desktop);
            }
         }

         public static SafeCoTaskMemHandleZeroIsInvalid GetItemIDList()
         {
             SafeCoTaskMemHandleZeroIsInvalid pidl;
             Guid guid = KnownFolderID;
             NativeMethod.SHGetKnownFolderIDList(
                ref guid, 0, IntPtr.Zero, out pidl);
             return pidl;
         }
     }
}

执行为:

string[] names = AppsFolder.GetItemNames(AppsFolder.ESHGDN.SHGDN_INFOLDER).ToArray();
for (int i=0; i<names.Length; i++)
{
    Console.WriteLine(names[i]);
}

ILaunchSourceAppUserModelID接口提供了一种获取AppUserModelID的方法,但我不确定如何通过IShellFolder接口访问此接口。另外,如何将AppsFolder虚拟文件夹中的实际文件位置获取到实际exe的文件路径?

通过在Windows PowerShell命令提示符中运行以下命令,可以获取为当前用户安装的所有应用程序的应用程序用户模型ID(AUMID):

get-StartApps

要获取为另一个用户安装的Windows应用商店应用的AUMID,请在Windows PowerShell命令提示符下运行以下命令:

$installedapps = get-AppxPackage

$aumidList = @()
foreach ($app in $installedapps)
{
    foreach ($id in (Get-AppxPackageManifest $app).package.applications.application.id)
    {
        $aumidList += $app.packagefamilyname + "!" + $id
    }
}

$aumidList

您可以参考“ Find the Application User Model ID of an installed app”中的更多详细信息。

您需要做的是从C#调用相关的注册表API或Powershell命令。

您使用 IShellFolder2.GetDetailsEx PKEY_AppUserModel_ID

获得AppUserModelId

(在Windows 10上的C#中测试)

[StructLayout(LayoutKind.Sequential, Pack = 4)]
public struct PROPERTYKEY
{
    private readonly Guid _fmtid;
    private readonly uint _pid;

    public PROPERTYKEY(Guid fmtid, uint pid)
    {
        _fmtid = fmtid;
        _pid = pid;
    }

    public static readonly PROPERTYKEY PKEY_AppUserModel_ID = new PROPERTYKEY(new Guid("9F4C2855-9F79-4B39-A8D0-E1D42DE1D5F3"), 5);     
}

简而言之,将Microsoft.WindowsAPICodePack-Shell nuget包添加到您的项目中,然后使用以下代码:

// GUID taken from https://docs.microsoft.com/en-us/windows/win32/shell/knownfolderid
var FODLERID_AppsFolder = new Guid("{1e87508d-89c2-42f0-8a7e-645a0f50ca58}");
ShellObject appsFolder = (ShellObject)KnownFolderHelper.FromKnownFolderId(FODLERID_AppsFolder);

foreach (var app in (IKnownFolder)appsFolder)
{
    // The friendly app name
    string name = app.Name;
    // The ParsingName property is the AppUserModelID
    string appUserModelID = app.ParsingName; // or app.Properties.System.AppUserModel.ID
    // You can even get the Jumbo icon in one shot
    ImageSource icon =  app.Thumbnail.ExtraLargeBitmapSource;
}

要启动该应用程序:

System.Diagnostics.Process.Start("explorer.exe", @" shell:appsFolder\" + appUserModelID);

适用于常规应用程序和商店应用程序。

我有一个解决方案,您无需添加任何其他dll或命名空间即可从窗口应用商店中获取应用名称:

//anything with this class
.pointer-column {
 cursor: pointer;
}
//grids (or other elements if you want) with the 'a-type-of-grid' class 
.a-type-of-grid {

  /*Some css just for this type of grid*/

  //overwrite the global pointer-column class
  .pointer-column {
    //css you want
  }
}

输出中包括所有应用程序列表。
