1.System.Windows.Forms.SendKeys
组合键:Ctrl = ^ 、Shift = + 、Alt = %
模拟按键:A
private void button1_Click(object sender, EventArgs e) { textBox1.Focus(); SendKeys.Send("{A}"); }
模拟组合键:CTRL + A
private void button1_Click(object sender, EventArgs e) { webBrowser1.Focus(); SendKeys.Send("^{A}"); }
SendKeys.Send // 异步模拟按键(不阻塞UI)
SendKeys.SendWait // 同步模拟按键(会阻塞UI直到对方处理完消息后返回)
//这种方式适用于WinForm程序,在Console程序以及WPF程序中不适用
2.keybd_event
DLL引用
[DllImport("user32.dll", EntryPoint = "keybd_event", SetLastError = true)] public static extern void keybd_event(Keys bVk, byte bScan, uint dwFlags, uint dwExtraInfo);
模拟按键:A
private void button1_Click(object sender, EventArgs e) { textBox1.Focus(); keybd_event(Keys.A, 0, 0, 0); }
模拟组合键:CTRL + A
public const int KEYEVENTF_KEYUP = 2; private void button1_Click(object sender, EventArgs e) { webBrowser1.Focus(); keybd_event(Keys.ControlKey, 0, 0, 0); keybd_event(Keys.A, 0, 0, 0); keybd_event(Keys.ControlKey, 0, KEYEVENTF_KEYUP, 0); }
3.PostMessage
上面两种方式都是全局范围呢,现在介绍如何对单个窗口进行模拟按键
模拟按键:A / 两次
[DllImport("user32.dll", EntryPoint = "PostMessageA", SetLastError = true)] public static extern int PostMessage(IntPtr hWnd, int Msg, Keys wParam, int lParam); public const int WM_CHAR = 256; private void button1_Click(object sender, EventArgs e) { textBox1.Focus(); PostMessage(textBox1.Handle, 256, Keys.A, 2); }
模拟组合键:CTRL + A
如下方式可能会失效,所以最好采用上述两种方式1
public const int WM_KEYDOWN = 256; public const int WM_KEYUP = 257; private void button1_Click(object sender, EventArgs e) { webBrowser1.Focus(); keybd_event(Keys.ControlKey, 0, 0, 0); keybd_event(Keys.A, 0, 0, 0); PostMessage(webBrowser1.Handle, WM_KEYDOWN, Keys.A, 0); keybd_event(Keys.ControlKey, 0, KEYEVENTF_KEYUP, 0); }
