想了很就也没有结果,请各位有没有好的办法!

Answer 1

楼主可以考虑用 System.Windows.Forms.SendKeys 或API实现组合键[DllImport("user32.dll")]
static extern void keybd_event(byte bVk, byte bScan, uint dwFlags,
   UIntPtr dwExtraInfo);

Answer 2

.net对组合键好象不太好，就用一楼的api吧！

可是api我接触的比较少,
[DllImport("user32.dll")]
static extern void keybd_event(byte bVk, byte bScan, uint dwFlags,
UIntPtr dwExtraInfo);
在c#中该如何使用?

//换下一个键
void PressKey( byte keyCode )
    {
        const int KEYEVENTF_EXTENDEDKEY = 0x1;
        const int KEYEVENTF_KEYUP       = 0x2;
        keybd_event( keyCode, 0x45, KEYEVENTF_EXTENDEDKEY, 0 );
        keybd_event( keyCode, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0 );
    }组合键其实是
keybd_event( keyCode_A, 0x45, KEYEVENTF_EXTENDEDKEY, 0 );
keybd_event( keyCode_B, 0x45, KEYEVENTF_EXTENDEDKEY, 0 );
keybd_event( keyCode_B, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0 );
