少有人走的路模拟按键在.Net中有三种方式实现。
第一种方式：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)
第二种方式：keybd_event
模拟按键：A
[DllImport("user32.dll", EntryPoint = "keybd_event", SetLastError = true)]public static extern void keybd_event(Keys bVk, byte bScan, uint dwFlags, uint dwExtraInfo);
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);
}
模拟组合键：CTRL + X ，CTRL + C ，CTRL + V ，CTRL + Z
[DllImport("user32.dll", EntryPoint = "keybd_event", SetLastError = true)] public static extern void keybd_event(Keys bVk, byte bScan, uint dwFlags, uint dwExtraInfo); public const int KEYEVENTF_KEYUP = 2;
private void InitSheet(FarPoint.Win.Spread.SheetView sheet)
{ // 列の設定
sheet.ColumnCount = 3; // 行の設定
sheet.RowCount = 9;
}
private void BtnCtrlX_Click(object sender, EventArgs e)
{
textBox1.Focus();
keybd_event(Keys.ControlKey, 0, 0, 0);
keybd_event(Keys.X, 0, 0, 0);
keybd_event(Keys.ControlKey, 0, KEYEVENTF_KEYUP, 0);
SendKeys.Send("^{X}");
}
private void BtnCtrlC_Click(object sender, EventArgs e)
{
textBox1.Focus();
keybd_event(Keys.ControlKey, 0, 0, 0);
keybd_event(Keys.C, 0, 0, 0);
keybd_event(Keys.ControlKey, 0, KEYEVENTF_KEYUP, 0);
SendKeys.Send("^{C}");
}
private void BtnCtrlV_Click(object sender, EventArgs e)
{
spreadEx1.Focus();
keybd_event(Keys.ControlKey, 0, 0, 0);
keybd_event(Keys.V, 0, 0, 0);
keybd_event(Keys.ControlKey, 0, KEYEVENTF_KEYUP, 0);
SendKeys.Send("^{V}");
}
private void BtnCtrlZ_Click(object sender, EventArgs e)
{
textBox1.Focus();
keybd_event(Keys.ControlKey, 0, 0, 0);
keybd_event(Keys.Z, 0, 0, 0);
keybd_event(Keys.ControlKey, 0, KEYEVENTF_KEYUP, 0);
SendKeys.Send("^{Z}");
}
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
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);//直接给你贴一个我自己写的类，模拟键盘输入字符using System.Runtime.InteropServices;
namespace lisonFunc
{ static class MyKey
{
[DllImport("user32.dll", EntryPoint = "keybd_event")]
private static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);
/// <summary>
/// 按一个键后等待一段时间 /// </summary>
/// <param name="keyCode">要按的键，如Keys.Enter</param>
/// <param name="wait">等待的时间（毫秒）</param>
public static void KeyPress(Keys keyCode, int wait)
{
keybd_event((byte)keyCode, 0, 0, 0);
keybd_event((byte)keyCode, 0, 2, 0);
Thread.Sleep(wait);
} /// <summary>
/// Ctrl+...组合键 /// </summary>
/// <param name="keyCode">要同时按下的键，如Keys.C</param>
public static void ControlKey(Keys keyCode)
{
keybd_event((byte)Keys.ControlKey, 0, 0, 0);
keybd_event((byte)keyCode, 0, 0, 0);
keybd_event((byte)keyCode, 0, 2, 0);
keybd_event((byte)Keys.ControlKey, 0, 2, 0);
} /// <summary>
/// 重复n次按某个键 /// </summary>
/// <param name="keyCode">要按的键，如Keys.Enter</param>
/// <param name="Times">按键次数</param>
/// <param name="wait">间隔时间（毫秒）</param>
public static void KeyPressRep(Keys keyCode, int Times, int wait)
{ for (int i = 0; i < Times; i++)
{
KeyPress(keyCode,wait);
}
} /// <summary>
/// 输入一串数字 /// </summary>
/// <param name="NumWords"></param>
public static void TypeNums(string NumWords)
{ foreach (char c in NumWords.ToCharArray())
{
KeyPress(48 + c, 50);
}
}
}
}
