Minimizing the Console Window in C#.

1. Introduction.

1.1 A few days ago, I was developing a console application written in C#.

1.2 One of the requirements of this application was that it must immediately minimize the console window on startup.

1.3 For the benefit of readers, I decided to post here the code for minimizing the console window of a managed application.

2. Example Code.

2.1 The code below demonstrates how this can be done :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;

namespace CSConsoleApp01
    class Program
        const Int32 SW_MINIMIZE = 6;

        [DllImport("Kernel32.dll", CallingConvention = CallingConvention.StdCall, SetLastError = true)]
        private static extern IntPtr GetConsoleWindow();

        [DllImport("User32.dll", CallingConvention = CallingConvention.StdCall, SetLastError = true)]
        [return: MarshalAs(UnmanagedType.Bool)]
        private static extern bool ShowWindow([In] IntPtr hWnd, [In] Int32 nCmdShow);

        private static void MinimizeConsoleWindow()
            IntPtr hWndConsole = GetConsoleWindow();
            ShowWindow(hWndConsole, SW_MINIMIZE);

        static void Main(string[] args)

2.2 I basically used the GetConsoleWindow() Windows API to obtain the window handle used by the console associated with the calling process.

2.3 I then use the ShowWindow() API using the window handle returned from GetConsoleWindow() and with the second parameter set to SW_MINIMIZE (value 6) to minimize the console window.




About Lim Bio Liong

I've been in software development for nearly 20 years specializing in C , COM and C#. It's truly an exicting time we live in, with so much resources at our disposal to gain and share knowledge. I hope my blog will serve a small part in this global knowledge sharing network. For many years now I've been deeply involved with C development work. However since circa 2010, my current work has required me to use more and more on C# with a particular focus on COM interop. I've also written several articles for CodeProject. However, in recent years I've concentrated my time more on helping others in the MSDN forums. Please feel free to leave a comment whenever you have any constructive criticism over any of my blog posts.

  1. Thanks a lot!
    Your solution is much more simplier (and with much less lines of code) than the ones i found on other sites.
