CMD Command doesn't execute

Question

I'm trying to run this command in cmd from c# but for some reason it doesn't work. But when I change my Argument to "/C ipconfig" it work perfectly. I don't understand why. What am I doing wrong? Here is my code:

   Process process = new Process();
        process.StartInfo.FileName = "cmd.exe";
        process.StartInfo.Arguments = $"/C wbadmin start backup - backupTarget:{TargetBackupDrive}: -include:{LocationOs}: -allcritical - quiet";
        process.StartInfo.CreateNoWindow = true;
        process.StartInfo.RedirectStandardOutput = true;
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardInput = true;
        process.StartInfo.Verb = "runas";
        process.Start();
        CmdOutput = process.StandardOutput.ReadToEnd();
        process.WaitForExit();

[The docs for wbadmin](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/wbadmin) say that it must run elevated. Is your app running as an admin? — Code Stranger, Jun 23 '21 at 16:10
Why do you `RedirectStandardInput = true` then never provide any input? — Dour High Arch, Jun 23 '21 at 16:10
Yeah, my bad I forgot to remove it. But it doesn't change anything. — Red hood, Jun 23 '21 at 16:11
@CodeStranger I'm writing in it visuals studio (which I run it as admin) and I added a Verb = "runas" so it will launch as an admin. — Red hood, Jun 23 '21 at 16:16
@OlivierRogier I checked those posts before I post my question. It didn't work. — Red hood, Jun 23 '21 at 16:19
The code you posted cannot work. You are trying to use `runas`, while at the same time set `UseShellExecute` to `false`. Since `wbadmin` requires an elevated process to work, the code you posted cannot work. — Peter Duniho, Jun 23 '21 at 16:27
Does code run outside VS? VS does not use Admin unless you right click the VS shortcut and select Run As Admin. — jdweng, Jun 23 '21 at 16:38
@PeterDuniho Even when I set it to true, it doen't execute at all. — Red hood, Jun 23 '21 at 16:41

The verb "runas" does not work when UseShellExecute is set to false as it is pointed out here: Set ProcessStartInfo.EnvironmentVariables when Verb="runas"

You could either provide admin credentials with the UserName and Password properties our set UseShellExecute to true and execute your command in the shell.

I tried to set the UseShellExecute to true. But It didn't change anything. – Red hood Jun 23 '21 at 16:30
