提升权限不UseShellExecute工作= FALSE

问题描述

限时删除！！

我要开始一个子进程（实际上是相同的，控制台应用程序），以提升的权限，但隐藏的窗口。

I want to start a child process (indeed the same, console app) with elevated privileges but with hidden window.

我接下来做：

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

var process = new Process
{
    StartInfo = info
};

process.Start();

和这个作品：

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

但 UseShellExecute = TRUE 创建一个新的窗口，我也我不能重定向输出。

But UseShellExecute = true creates a new window and I also I can't redirect output.

所以下次当我这样做：

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();

这不提升权限和code以上返回false。为什么？

This doesn't elevate privileges and code above returns false. Why??

推荐答案

如果该过程由开始的ShellExecuteEx将ProcessStartInfo.Verb只能有一个效果（）。这就要求UseShellExecute = TRUE。 I / O重定向和隐藏窗口，如果过程由CreateProcess的启动只能工作（）。这就要求UseShellExecute =假的。

ProcessStartInfo.Verb will only have an effect if the process is started by ShellExecuteEx(). Which requires UseShellExecute = true. Redirecting I/O and hiding the window can only work if the process is started by CreateProcess(). Which requires UseShellExecute = false.

好吧，这就是为什么它不工作。不知道是否禁止启动隐藏进程绕过UAC是故意的。大概。的非常的可能。

Well, that's why it doesn't work. Not sure if forbidding to start a hidden process that bypasses UAC was intentional. Probably. Very probably.

检查this螺纹的清单，你需要显示UAC提升提示。

Check this thread for the manifest you need to display the UAC elevation prompt.
