打开浏览器。在64位操作系统上使用32位任务执行跳转任务。

I have a 32 bit application that I want to register opening "explorer.exe" as a jump task. It works fine on 32 bit Windows 7, but in 64 bit Windows, it gives an error "C:\Windows\system32\explorer.exe Unspecified error".

我有一个32位的应用程序，我想注册打开“资源管理器”。作为一项跳跃任务。它在32位Windows 7上运行良好，但在64位Windows中，它给出了一个错误“C:\Windows\system32\explorer”。exe不明错误”。

Since Explorer's full path is "C:\Windows\SysWOW64\explorer.exe", I assume this is a result of Windows seeing the 32 bit emulated path at at run time, but the jump list needs the full 64 bit path. Is there a simple way to build this jumplist that will work on a 64 bit OS?

因为Explorer的完整路径是“C:\Windows\SysWOW64\ Explorer”。我假设这是Windows在运行时看到32位模拟路径的结果，但是跳转列表需要完整的64位路径。有没有一种简单的方法来构建这个能在64位操作系统上运行的jumplist ?

I guess I could do a check of Environment.Is64BitOperatingSystem and hardcode the location to "C:\Windows\SysWow64" if it's set, but I it's bad to be using hardcoded paths.

我想我可以检查一下环境。Is64BitOperatingSystem和hardcode的位置是“C:\Windows\SysWow64”，如果是设置的话，但是使用硬编码的路径是不好的。

string exe = System.Reflection.Assembly.GetExecutingAssembly().Location;
string current = System.IO.Path.GetDirectoryName(exe);
var jl = new System.Windows.Shell.JumpList();
jl.ShowFrequentCategory = false;
jl.ShowRecentCategory = false;
jl.BeginInit();
jl.JumpItems.AddRange(new[]
    {
        new System.Windows.Shell.JumpTask
        {
            Title = "Explore",
            ApplicationPath = "explorer.exe",
            IconResourcePath = "explorer.exe",
            Arguments = "/select,\"" + exe,
            WorkingDirectory = current,
        },
        // other jump tasks here
    });
jl.EndInit();
jl.Apply();

I found the answer here How to start a 64-bit process from a 32-bit process

我在这里找到了如何从32位进程启动64位进程的答案。

The "sysnative" thing doesn't work in this scenario, but disabling filesystem redirection temporarily works:

在这种情况下，“sysnative”功能不起作用，但是禁用文件系统重定向临时工作:

[DllImport("kernel32.dll", SetLastError = true)]
private static extern bool Wow64DisableWow64FsRedirection(ref IntPtr ptr);
[DllImport("kernel32.dll", SetLastError = true)]
private static extern bool Wow64RevertWow64FsRedirection(IntPtr ptr);

    if (Environment.Is64BitOperatingSystem && !Environment.Is64BitProcess)
        Wow64DisableWow64FsRedirection(ref ptr);
    try
    {
        // Add jump list code
    }
    finally
    {
        if (Environment.Is64BitOperatingSystem && !Environment.Is64BitProcess)
            Wow64RevertWow64FsRedirection(ptr);
    }
