ProcessStartInfo 动词 runas 不起作用

Question

What is wrong with the following code?

        ProcessStartInfo startInfo = default(ProcessStartInfo);

        startInfo = new ProcessStartInfo(SetupProgramPath)
        {
            UseShellExecute = true,
            Verb = "runas",
            WindowStyle = ProcessWindowStyle.Normal,
            CreateNoWindow = false
        };

        Process.Start(startInfo); 

It is expected to prompt for credentials but nothing shows up. The system has the UAC enabled and not supposed to be changed. I appreciate your help in this one. Thank you in advance.

Answer 1

I have worked this out with the following code

ProcessStartInfo startInfo = default(ProcessStartInfo);

startInfo = new ProcessStartInfo(SetupProgramPath)
{
    UseShellExecute = true,
    Verb = "runas",
    WindowStyle = ProcessWindowStyle.Normal,
    FileName = "msiexec",
    Arguments = "/i \"" + SetupProgramPath + "\"",
    CreateNoWindow = false
};

Process.Start(startInfo);

If you want to ask the user to enter credentials of a different user, then use "runasuser":

ProcessStartInfo startInfo = new ProcessStartInfo(SetupProgramPath)
{
    UseShellExecute = true,
    Verb = "runasuser",
    WindowStyle = ProcessWindowStyle.Normal,
    CreateNoWindow = false
};

Process.Start(startInfo);
