Window Hiding with C#

Question

I compiled a C# program to an exe file. When I double-click the exe file from windows explorer, the program starts along with a black command line window. How can I start this file from windows explorer without showing the command line window

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    
    private static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
    private const int HIDE = 0;
    private const int MAXIMIZE = 3;
    private const int MINIMIZE = 6;
    private const int RESTORE = 9;
    
    Process cmd = new Process();
    cmd.StartInfo.FileName = Path.Combine(path, "Launcher.exe");
    cmd.StartInfo.RedirectStandardInput = true;
    cmd.StartInfo.CreateNoWindow = true;
    cmd.StartInfo.UseShellExecute = false;
    cmd.Start();
    cmd.StandardInput.WriteLine(argHandlerArgs);
    cmd.StandardInput.Flush();
    cmd.StandardInput.Close();
    
    ShowWindow(cmd.MainWindowHandle, 0);

If this is Windows Forms that youre talking about, then in the project properties you set the output type to Windows Application

You can use ShowWindowApi to hide your command line.

Here is an example

using System.Runtime.InteropServices

class CommandLine
{

    [DllImport("user32.dll")]
    static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

    [DllImport("Kernel32")]
    private static extern IntPtr GetConsoleWindow();

    const int SW_HIDE=0;
    const int SW_SHOW=5;

    static void Main(string[] args)
    {
         IntPtr hwnd;
         hwnd=GetConsoleWindow();
         ShowWindow(hwnd,SW_HIDE);
    }
}
