运行过程由非管理员应用程序管理员 [英] Run process as administrator from a non-admin application

问题描述

这是一个没有被以管理员身份运行的应用程序，我有以下代码：

From an application that is not being run as administrator, I have the following code:

ProcessStartInfo proc = new ProcessStartInfo();
proc.WindowStyle = ProcessWindowStyle.Normal;
proc.FileName = myExePath;
proc.CreateNoWindow = false;
proc.UseShellExecute = false;
proc.Verb = "runas";

当我打电话的Process.Start（PROC），我没有得到一个弹出询问您是否允许以管理员身份运行，而该exe是不以管理员身份运行。

When I call Process.Start(proc), I do not get a pop up asking for permission to run as administrator, and the exe is not run as administrator.

我尝试添加一个app.manifest在myExePath找到可执行文件，并更新了requestedExecutionLevel到

I tried adding an app.manifest to the executable found at myExePath, and updated the requestedExecutionLevel to

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

通过更新app.manifest，上的Process.Start（PROC）电话，我得到一个异常，请求的操作需要提升。

With the updated app.manifest, on the Process.Start(proc) call, I get an exception, "The requested operation requires elevation."

为什么不是.Verb动作没有设置管理员权限？

Why isn't the .Verb action not setting administrator privileges?

我测试的Windows Server 2008 R2标准上。

I am testing on Windows Server 2008 R2 Standard.

推荐答案

您的必须的使用的ShellExecute 。 ShellExecute的是一个知道如何启动 Consent.exe 为了提升仅API。

You must use ShellExecute. ShellExecute is the only API that knows how to launch Consent.exe in order to elevate.

在C＃中，你叫的ShellExecute 的方法是使用过程。开始与 UseShellExecute = TRUE 以及

In C#, the way you call ShellExecute is to use Process.Start along with UseShellExecute = true:

private void button1_Click(object sender, EventArgs e)
{
   ProcessStartInfo info = new ProcessStartInfo(@"C:\Windows\Notepad.exe");
   info.UseShellExecute = true;
   info.Verb = "runas";
   Process.Start(info);
}

如果你想成为一个优秀的开发人员，你可以当用户点击赶上否

If you want to be a good developer, you can catch when the user clicked No:

private void button1_Click(object sender, EventArgs e)
{
   const int ERROR_CANCELLED = 1223; //The operation was canceled by the user.

   ProcessStartInfo info = new ProcessStartInfo(@"C:\Windows\Notepad.exe");
   info.UseShellExecute = true;
   info.Verb = "runas";
   try
   {
      Process.Start(info);
   }
   catch (Win32Exception ex)
   {
      if (ex.NativeErrorCode == ERROR_CANCELLED)
         MessageBox.Show("Why you no select Yes?");
      else
         throw;
   }
}

红利观看

• UAC - 什么。怎么样。为什么。。 UAC的架构，并解释说，的CreateProcess 不能做抬高，只能创建一个过程。 的ShellExecute 用谁知道如何启动Consent.exe，并Consent.exe是谁检查组策略选项之一的人。



Bonus Watching

• UAC - What. How. Why.. The architecture of UAC, explaining that CreateProcess cannot do elevation, only create a process. ShellExecute is the one who knows how to launch Consent.exe, and Consent.exe is the one who checks group policy options.
