C# console application icon

Question

Does anyone know how to set a C# console application\'s icon in the code (not using project properties in Visual Studio)?

Answer 1

Here is a solution to change icon by code:

class IconChanger
{
    public static void SetConsoleIcon(string iconFilePath)
    {
        if (Environment.OSVersion.Platform == PlatformID.Win32NT)
        {
            if (!string.IsNullOrEmpty(iconFilePath))
            {
                System.Drawing.Icon icon = new System.Drawing.Icon(iconFilePath);
                SetWindowIcon(icon);
            }
        }
    }
    public enum WinMessages : uint
    {
        /// 

        /// An application sends the WM_SETICON message to associate a new large or small icon with a window. 
        /// The system displays the large icon in the ALT+TAB dialog box, and the small icon in the window caption. 
        /// 
        SETICON = 0x0080,
    }

    [System.Runtime.InteropServices.DllImport("user32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)]
    private static extern IntPtr SendMessage(IntPtr hWnd, int Msg, int wParam, IntPtr lParam);


    private static void SetWindowIcon(System.Drawing.Icon icon)
    {
        IntPtr mwHandle = System.Diagnostics.Process.GetCurrentProcess().MainWindowHandle;
        IntPtr result01 = SendMessage(mwHandle, (int)WinMessages.SETICON, 0, icon.Handle);
        IntPtr result02 = SendMessage(mwHandle, (int)WinMessages.SETICON, 1, icon.Handle);
    }// SetWindowIcon()
}
