我们测试软件功能，有时候需要不停操作按键和鼠标。通过虚拟按键和模拟鼠标操作可以轻松完成重复而繁琐的操作，节省人工时间和人为失误。虚拟按键和模拟鼠标操作还可以实现对远程电脑的按键和鼠标操作，实现屏幕协助。
虚拟按键可通过Keybd_event实现
public class Key
{
[DllImport("user32.dll")]
public static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, uint dwExtraInfo);
//按键按下
private static readonly byte KEYEVENTF_KEYDOWN = 0x0000;
//按键弹起
private static readonly byte KEYEVENTF_KEYUP = 0x0002;
public static readonly byte VK_Enter = 0x0D;
public static void ClickKey(byte key)
{
keybd_event(key, 0, KEYEVENTF_KEYDOWN, 0);
keybd_event(key, 0, KEYEVENTF_KEYUP, 0);
}
}
void Main()
{
//点击一下Enter键
Key.ClickKey(Key.VK_Enter);
}
模拟鼠标操作使用mouse_event函数
public class Mouse
{
[DllImport("user32", CharSet = CharSet.Unicode)]
private static extern int mouse_event(int dwFlags, int dx, int dy, int dwData, int dwExtraInfo);
//移动鼠标
const int MOUSEEVENTF_MOVE = 0x0001;
//模拟鼠标左键按下
const int MOUSEEVENTF_LEFTDOWN = 0x0002;
//模拟鼠标左键抬起
const int MOUSEEVENTF_LEFTUP = 0x0004;
//模拟鼠标右键按下
const int MOUSEEVENTF_RIGHTDOWN = 0x0008;
//模拟鼠标右键抬起
const int MOUSEEVENTF_RIGHTUP = 0x0010;
//模拟鼠标中键按下
const int MOUSEEVENTF_MIDDLEDOWN = 0x0020;
//模拟鼠标中键抬起
const int MOUSEEVENTF_MIDDLEUP = 0x0040;
//标示是否采用绝对坐标
const int MOUSEEVENTF_ABSOLUTE = 0x8000;
[DllImport("User32.dll")]
//读取光标位置
public extern static bool GetCursorPos(ref Point pot);
[DllImport("User32.dll")]
//设置光标位置
public extern static void SetCursorPos(int x, int y);
//鼠标左键单击一次
public static void LeftMouseClick()
{
mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
}
//鼠标右键键单击一次
public static void RightMouseClick()
{
mouse_event(MOUSEEVENTF_RIGHTDOWN | MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0);
}
//双击一次
public static void DoubleLeftClick()
{
mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
}
//设置绝对路径点击一次
public static void SetClickPosition(int x,int y)
{
mouse_event(MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE, x, y, 0, 0);
}
}
void Main()
{
//横坐标x为200，纵坐标为500位置点击了一下，屏幕原点坐标为左上角
Mouse.SetClickPosition(200, 500);
}
