launching SFC from within a C# app

Question

I have been searching and I cannot seem to get this work. I am trying to launch SFC from a button in a C# app. I am aware that it requires rights elevation and in the scope of what I am trying to do is behavior that I want.

I have tried: To run cmd as administrator along with command? Running CMD as administrator with an argument from C# and C# how to run a process(with arguments) through an administrator elevated cmd

The code I tried last was:

private void button6_Click(object sender, EventArgs e)
    {
        ProcessStartInfo procStartInfo = new ProcessStartInfo("cmd", "/c " + "processNeedToRun")
        {
            RedirectStandardError = true,
            RedirectStandardOutput = true,
            UseShellExecute = false,
            CreateNoWindow = true,
            Verb = "runas"
        };

    }

I either get no process launching at all the cmd window flashes saying incorrect credentials or the command was incorrect.

what am I doing wrong?

Per the comment added I changed it to this:

private void button6_Click(object sender, EventArgs e)
    {
        ProcessStartInfo procStartInfo = new ProcessStartInfo("cmd", "/c " + "sfc.exe /scannow")
        {
            RedirectStandardError = false,
            RedirectStandardOutput = false,
            UseShellExecute = true,
            CreateNoWindow = false,
            Verb = "runas"
        };

    }

and no change

EDIT:

So I managed to find a solution:

I created a new console app, edited the manifest to require admin and did this

Process.Start("CMD.exe", " /c SFC /Scannow");

That does have the behavior I want. Thanks for the help!

Answer 1

Your console is not elevating, the problem is you can either use the Verb = "runas" and have it elevate or you can use UseShellExecute = false and redirect the outputs, you can not have both .

Your three options are:

1. Use UseShellExecute = true and disable the redirections
2. Add a manifest file to your program so it elevates itself as an administrator on start and it can then in turn launch administrative processes and monitor them.
3. Do a combination of both by writing a 2nd exe that has a manifest file that always runs as administrator. Then have your 1st program launch the 2nd program with Verb = "runas" , you then have your 2nd program start SFC with UseShellExecute = false . Your 2nd program then forwards the output via some form of IPC ( WCF over named pipes would likely be easiest) to the first unelevated program to be displayed to the user.

尝试设置ProcesStartInfo.UserName和ProcessStartInfo.Password来使用更高的凭据模拟新进程。
