How to send "Win + R" in C#



using System.Runtime.InteropServices;
using System.Windows.Forms;

static class KeyboardSend
{
    [DllImport("user32.dll")]
    private static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

    private const int KEYEVENTF_EXTENDEDKEY = 1;
    private const int KEYEVENTF_KEYUP = 2;

    public static void KeyDown(Keys vKey)
    {
        keybd_event((byte)vKey, 0, KEYEVENTF_EXTENDEDKEY, 0);
    }

    public static void KeyUp(Keys vKey)
    {
        keybd_event((byte)vKey, 0, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);
    }
}


Then use the below to press Win+R

KeyboardSend.KeyDown(Keys.LWin);
KeyboardSend.KeyDown(Keys.R);
KeyboardSend.KeyUp(Keys.R);
KeyboardSend.KeyUp(Keys.LWin);
