提升权限不适用于UseShellExecute=false

我想用提升的权限启动一个子进程(实际上是同一个控制台应用程序),但要隐藏窗口。

下一步我做:

var info = new ProcessStartInfo(Assembly.GetEntryAssembly().Location)
{
    UseShellExecute = true, // !
    Verb = "runas", 
};

var process = new Process
{
    StartInfo = info
};

process.Start();

这是有效的:

var identity = new WindowsPrincipal(WindowsIdentity.GetCurrent());
identity.IsInRole(WindowsBuiltInRole.Administrator); // returns true

UseShellExecute = true 创建一个新窗口,我也不能重定向输出。

所以当我下一步做的时候:

var info = new ProcessStartInfo(Assembly.GetEntryAssembly().Location)
{
    RedirectStandardError = true,
    RedirectStandardOutput = true,
    UseShellExecute = false, // !
    Verb = "runas"
};

var process = new Process
{
    EnableRaisingEvents = true,
    StartInfo = info
};

DataReceivedEventHandler actionWrite = (sender, e) =>
{
    Console.WriteLine(e.Data);
};

process.ErrorDataReceived += actionWrite;
process.OutputDataReceived += actionWrite;

process.Start();
process.BeginOutputReadLine();
process.BeginErrorReadLine();
process.WaitForExit();

这不会提升特权,并且上面的代码返回false。为什么?
