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

Question

I googled around for information on how to hide one’s own console window. Amazingly, the only solutions I could find were hacky solutions that involved FindWindow() to find the console window by its title. I dug a bit deeper into the Windows API and found that there is a much better and easier way, so I wanted to post it here for others to find.

How do you hide (and show) the console window associated with my own C# console application?

Answer 1

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);
