为什么冒充的过程回报"目录名称是无效的"？ [英] Why does impersonating a process return "The directory name is invalid"?

问题描述

我有一个需要在管理员权限运行的过程。我需要普通人运行的过程中，但我不想给大家访问...所以我创建了一个简单的类，将执行此一个任务作为管理员，使用模拟。

I have a process that needs to run under administrative privileges. I need the average joe to run the process, but I don't want to give everyone access... so I've created a simple class that will run this ONE task as an administrator, using impersonation.

代码很striaght进，但我不明白这是为什么崩溃。 HELP ?? !!

The code is VERY striaght-forward, but I can't understand why this is crashing. HELP??!!

我通过一个批处理文件运行此，我甚至已经复制需要执行到本地硬盘驱动器的文件，认为这可能是运行在网络上的应用程序权限问题。

I'm running this via a batch file, and I've even copied the file that needs to execute to the local hard drive, thinking this might be a permission issue for running an app over the network.

    public static Process ImpersonateProcess(string exe, string args, string Username, string Password)
    {
        ProcessStartInfo psi = new ProcessStartInfo(exe);
        psi.Arguments = args;
        psi.UseShellExecute = false;
        psi.UserName = Username;

        psi.Password = new SecureString();

        foreach (char c in Password.ToCharArray())
        {
            psi.Password.AppendChar(c);
        }

        Process proc = null;

        Console.WriteLine("starting...");
        proc = Process.Start(psi);
        Console.WriteLine("started");

        return proc;
    }

在上面的代码中，我从来没有开始。它抛出的的Process.Start（PSI）的错误，并与一个错误信息目录名称是无效的。

In the code above, I never get to "started". It throws an error in the Process.Start(psi) and with an error message of "the directory name is invalid."

推荐答案

这可能是因为你没有设置工作目录财产。按照
文档：

It could be because you're not setting the WorkingDirectory property. According to the docs:

重要提示：

如果提供了用户名和密码，必须设置的工作目录属性。如果没有设置该属性，默认的工作目录是％SYSTEMROOT％\system32。

The WorkingDirectory property must be set if UserName and Password are provided. If the property is not set, the default working directory is %SYSTEMROOT%\system32.
