通过NetworkIsolationEnumAppContainers查看安装的UWP应用

很多时候有启动UWP的程序需求，启动之前检查一下当前程序是否存在。

比如我们查看显示名称、工作路径、包名等等。都可以通过NetworkIsolationEnumAppContainers方法获取，这个代码是在通过NetworkIsolationEnumAppContainers 检索到的github上的一个代码，减去一些不需要的部分后，剩余的代码：

LoopUtil.cs

public class LoopUtil
    {
        internal List<LoopUtil.INET_FIREWALL_APP_CONTAINER> _AppList;
        internal IntPtr _pACs;
        public LoopUtil()
        {
            LoadApps();
        }
        private List<INET_FIREWALL_APP_CONTAINER> PI_NetworkIsolationEnumAppContainers()
        {
            IntPtr arrayValue = IntPtr.Zero;
            uint size = 0;
            var list = new List<INET_FIREWALL_APP_CONTAINER>();

            GCHandle handle_pdwCntPublicACs = GCHandle.Alloc(size, GCHandleType.Pinned);
            GCHandle handle_ppACs = GCHandle.Alloc(arrayValue, GCHandleType.Pinned);
            uint retval = NetworkIsolationEnumAppContainers((Int32)NETISO_FLAG.NETISO_FLAG_MAX, out size, out arrayValue);
            _pACs = arrayValue; //store the pointer so it can be freed when we close the form
            var structSize = Marshal.SizeOf(typeof(INET_FIREWALL_APP_CONTAINER));
            for (var i = 0; i < size; i++)
            {
                var cur = (INET_FIREWALL_APP_CONTAINER)Marshal.PtrToStructure(arrayValue, typeof(INET_FIREWALL_APP_CONTAINER));
                list.Add(cur);
                arrayValue = new IntPtr((long)(arrayValue) + (long)(structSize));
            }

            //release pinned variables.
            handle_pdwCntPublicACs.Free();
            handle_ppACs.Free();

            return list;

        }
        public void LoadApps()
        {

            _AppList = PI_NetworkIsolationEnumAppContainers();

        }


        [StructLayoutAttribute(LayoutKind.Sequential)]
        internal struct INET_FIREWALL_APP_CONTAINER
        {
            internal IntPtr appContainerSid;
            internal IntPtr userSid;
            [MarshalAs(UnmanagedType.LPWStr)]
            public string appContainerName;
            [MarshalAs(UnmanagedType.LPWStr)]
            public string displayName;
            [MarshalAs(UnmanagedType.LPWStr)]
            public string description;
            internal INET_FIREWALL_AC_CAPABILITIES capabilities;
            internal INET_FIREWALL_AC_BINARIES binaries;
            [MarshalAs(UnmanagedType.LPWStr)]
            public string workingDirectory;
            [MarshalAs(UnmanagedType.LPWStr)]
            public string packageFullName;
        }

        [StructLayoutAttribute(LayoutKind.Sequential)]
        internal struct INET_FIREWALL_AC_CAPABILITIES
        {
            public uint count;
            public IntPtr capabilities;
        }
        [StructLayoutAttribute(LayoutKind.Sequential)]
        internal struct INET_FIREWALL_AC_BINARIES
        {
            public uint count;
            public IntPtr binaries;
        }

        [DllImport("FirewallAPI.dll")]
        internal static extern uint NetworkIsolationEnumAppContainers(uint Flags, out uint pdwCntPublicACs, out IntPtr ppACs);

        enum NETISO_FLAG
        {
            NETISO_FLAG_FORCE_COMPUTE_BINARIES = 0x1,
            NETISO_FLAG_MAX = 0x2
        }

    }

MainWindow.xaml的构造函数中添加引用

  LoopUtil loopUtil = new LoopUtil();
            loopUtil.LoadApps();
            var uwpTempApplist = loopUtil._AppList;

uwpTemoApplist中就是存放的UWP相关参数。
