C # simulate mouse and keyboard operations

A simple class that simulates keyboard and mouse operations. Expand the virtualkeys enumeration, or write it directly!

Using system;
Using system. runtime. interopservices;
Using system. text;
Class keyboard
{
Const uint keyeventf_extendedkey = 0x1;
Const uint keyeventf_keyup = 0x2;
[Dllimport ("user32.dll")]
Static extern short getkeystate (INT foreign rtkey );
[Dllimport ("user32.dll")]
Static extern void keybd_event (
Byte bvk,
Byte bscan,
Uint dwflags,
Uint dwextrainfo
);

Public Enum virtualkeys: byte
{
Vk_numlock = 0x90, // number lock key
Vk_scroll = 0x91, // scroll to lock
Vk_capital = 0x14, // case-sensitive lock
Vk_a = 62
}

Public static bool getstate (virtualkeys key)
{
Return (getkeystate (INT) Key) = 1 );
}
Public static void setstate (virtualkeys key, bool state)
{
If (State! = Getstate (key ))
{
Keybd_event (
(Byte) key,
0x45,
Keyeventf_extendedkey | 0,
0
);
Keybd_event (
(Byte) key,
0x45,
Keyeventf_extendedkey | keyeventf_keyup,
0
);
}
}
}

Example:
Simulated operation
Keyboard. setstate (
Virtualkeys. vk_capital,
! Keyboard. getstate (virtualkeys. vk_capital)
);
Obtain the keyboard status
Keyboard. getstate (virtualkeys. vk_capital)

* An IBM compatible keyboard with a decimal value identifier

I suddenly found that there was another one in C #.System. Windows. Forms. sendkeys

However, this can only simulate a keyboard.

 

Here is the code that can really simulate mouse operations! I am looking for something so hard!

Function declaration:
Private readonly int mouseeventf_leftdown = 0x2;
Private readonly int mouseeventf_leftup = 0x4;
[Dllimport ("USER32")]
Public static extern void mouse_event (INT dwflags, int dx, int dy, int dwdata, int dwextrainfo );

Call method:
Mouse_event (mouseeventf_leftdown, x * 65536/1024, y * 65536/768, 0, 0 );
Mouse_event (mouseeventf_leftup, x 65536/1024, y * 65536/768, 0, 0 );
X and Y are the abscissa and ordinate of the point you want to click.
