Show/Hide the console window of a C# console application

Just go to the application's Properties and change the Output type from Console Application to Windows Application.

Here’s how:

using System.Runtime.InteropServices;

---

[DllImport("kernel32.dll")]
static extern IntPtr GetConsoleWindow();

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

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

---

var handle = GetConsoleWindow();

// Hide
ShowWindow(handle, SW_HIDE);

// Show
ShowWindow(handle, SW_SHOW);

Why do you need a console application if you want to hide console itself? =)

I recommend setting Project Output type to Windows Application instead of Console application. It will not show you console window, but execute all actions, like Console application do.
