Asy*_*Asy 3 .net c# windows winapi known-folders
我想要获取在 Windows 10 上安装并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 应用程序,我想获取其 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,我已经尝试过:1)遍历注册表并迭代已安装的应用程序。但是,此方法会遍历所有已安装的应用程序,返回的列表将包括类似的内容microsoft asp.net core 2.1.8 shared framework (x64)
,我想消除这些内容。
2)我发现我可以Appsfolder
通过shell:Appsfolder
在资源管理器窗口或运行中输入特殊内容来访问我想要的内容。到目前为止,我能够访问该文件夹,并遍历项目并列出文件的名称。但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]);

该ILaunchSourceAppUserModelID
接口提供了一种获取 AppUserModelID 的方法,但我不确定如何通过我的 IShellFolder 接口访问该接口。另外,如何获取 AppsFolder 虚拟文件夹中的实际文件位置到实际 exe 文件路径?
看看这个答案。
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://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;
}
