Rename a Windows Computer / Server with C# WPF

Question

I am trying to create a Configuration Tool for new devices, which has to be set up.

That's why I am trying to set the local hostname with a Button.

I want to use the name which I wrote in a textbox

public void SetMachineName(string newName)
    {

        // Create a new process
        ProcessStartInfo process = new ProcessStartInfo();

        // set name of process to "WMIC.exe"
        process.FileName = "WMIC.exe";

        // pass rename PC command as argument
        process.Arguments = "computersystem where caption='" + System.Environment.MachineName + "' rename " + newName;

        // Run the external process & wait for it to finish
        using (Process proc = Process.Start(process))
        {
            proc.WaitForExit();

            // print the status of command
            Console.WriteLine("Exit code = " + proc.ExitCode);
        }
    }

    public void Click_sethostname(object sender, RoutedEventArgs e)
    {
        SetMachineName(Textbox_sethostname.Text);
    }
