如何使用C＃隐藏命令窗口

Question

Building a console app that will execute an exe file(pagesnap.exe). I would like to hide its window(pagesnap.exe) during execution. How is it done.

ProcessStartInfo Psi = new ProcessStartInfo("D:\\PsTools\\");
Psi.FileName = "D:\\PsTools\\psexec.exe";    
Psi.Arguments = @"/C \\DESK123 D:\files\pagesnap.exe";
Psi.UseShellExecute = false;
Psi.RedirectStandardOutput = true;
Psi.RedirectStandardInput = true;
Psi.WindowStyle = ProcessWindowStyle.Hidden;
Psi.CreateNoWindow = true;
Process.Start(Psi).WaitForExit();

DESK123 is the local PC. Would later try this with remote PCs.

Things I have tried

Psi.Arguments = @"/C start /b psexec \\DESK123 D:\files\pagesnap.exe";  
Psi.Arguments = @"/b psexec \\DESK123 D:\files\pagesnap.exe";  
Psi.Arguments = @"/C psexec \\DESK123 /b D:\files\pagesnap.exe"; 
Psi.Arguments = @"/C psexec \\DESK123 D:\files\pagesnap.exe 2>&1 output.log";

Update: I have built pagesnap with Output type as a windows application instead of console. The cmd window doesn't come up, now. Seems this is the only way for me

Simply call the following function. Pass the argument as your command and your working directory

private string BatchCommand(string cmd, string mapD)
    {


        System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo("cmd", "/c " + cmd);
        procStartInfo.WorkingDirectory = mapD;
        // The following commands are needed to redirect the standard output.
        // This means that it will be redirected to the Process.StandardOutput StreamReader.
        procStartInfo.RedirectStandardOutput = true;
        procStartInfo.RedirectStandardError = true;
        procStartInfo.RedirectStandardInput = true;
        procStartInfo.UseShellExecute = false;
        // Do not create the black window.
        procStartInfo.CreateNoWindow = true;
        // Now we create a process, assign its ProcessStartInfo and start it
        System.Diagnostics.Process cmdProcess = new System.Diagnostics.Process();
        cmdProcess.StartInfo = procStartInfo;
        cmdProcess.ErrorDataReceived += cmd_Error;
        cmdProcess.OutputDataReceived += cmd_DataReceived;
        cmdProcess.EnableRaisingEvents = true;
        cmdProcess.Start();
        cmdProcess.BeginOutputReadLine();
        cmdProcess.BeginErrorReadLine();
        cmdProcess.StandardInput.WriteLine("ping www.google.com");     //Execute ping
        cmdProcess.StandardInput.WriteLine("exit");                  //Execute exit.
        cmdProcess.WaitForExit();

        // Get the output into a string

        return Batchresults;
    }
    static void cmd_DataReceived(object sender, DataReceivedEventArgs e)
    {
        if (e.Data != null)
            Batchresults += Environment.NewLine + e.Data.ToString();

    }

     void cmd_Error(object sender, DataReceivedEventArgs e)
    {
        if (e.Data != null)
        {
            Batchresults += Environment.NewLine + e.Data.ToString();

        }
    }
