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



我想获取一个在Windows 10上安装和可执行的应用程序的列表 - 即用户可以启动的应用程序可执行文件(UWP和非UWP(。对于UWP应用程序,我想获得其appusermodelid。对于非UWP应用程序,我想获取可执行文件的文件位置。

到目前为止,我已经尝试了:1(遍历注册表并遍历已安装的应用程序。但是,此方法通过所有已安装的应用程序,返回的列表将包括我想消除的microsoft asp.net core 2.1.8 shared framework (x64)之类的内容。

2(我发现可以通过将shell:Appsfolder键入Explorer窗口或运行,可以通过特殊Appsfolder访问我想要的东西。到目前为止,我能够访问此文件夹,并通过项目迭代并列出文件的名称。但是我不确定如何收集有关appusermodelid(适用于UWP应用程序(和filepath(用于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,但是我不确定如何通过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FilePath?

简而言

// GUID taken from https://learn.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;
}

启动应用程序:

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

适用于常规应用程序和存储应用程序。

我有解决方案,您无需添加任何额外的dll或名称空间即可从Window App Store获取应用程序名称:

            Process p = new Process();
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.CreateNoWindow = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
            p.StartInfo.FileName = "powershell.exe";
            p.StartInfo.Arguments = @"Get-AppxPackage | select name";
            p.Start();
            output = p.StandardOutput.ReadToEnd();
            p.WaitForExit();

输出中包含的所有应用程序列表。

您可以通过在Windows PowerShell命令提示中运行以下命令来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

要为另一个用户安装Windows Store应用程序的Aumids,请在Windows PowerShell命令提示中运行以下命令:

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

更多详细信息您可以参考"查找已安装应用程序的应用程序用户模型ID"。

您需要做的是从C#。

ishellfolder2.getDetailsex pekey_appusermodel_id

(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);     
}
