模拟按键c＃

这是一个例子

static class Program{    [Dllimport("user32.dll")]    public static extern int SetForegroundWindow(IntPtr hWnd);    [STAThread]    static void Main()    {        while(true)        { Process [] processes = Process.GetProcessesByName("iexplore"); foreach(Process proc in processes) {     SetForegroundWindow(proc.MainWindowHandle);     SendKeys.SendWait("{F5}"); } Thread.Sleep(5000);        }    }}

更好的…更少的烦恼…

static class Program{    const UInt32 WM_KEYDOWN = 0x0100;    const int VK_F5 = 0x74;    [Dllimport("user32.dll")]    static extern bool PostMessage(IntPtr hWnd, UInt32 Msg, int wParam, int lParam);    [STAThread]    static void Main()    {        while(true)        { Process [] processes = Process.GetProcessesByName("iexplore"); foreach(Process proc in processes)     PostMessage(proc.MainWindowHandle, WM_KEYDOWN, VK_F5, 0); Thread.Sleep(5000);        }    }}
