我想通过一个按键实现“Ctrl+F”这个键盘事件，但不知道代码该如何编写，请赐教

[hahabafeite]

我真是新手，在网上找到这个方法，但是编不出，麻烦大神看下其中我不懂的几个比较基本的东西：
1.FormCreate中注册热键：
这个FormCreate怎么写，我需要建立一个空的C#还是什么项目，空的C#出来就是namespace Project5
{
class Class1
{
}
} ？
RegisterHotKey(Handle, 125, MOD_CONTROL + MOD_ALT, $58); {Ctrl+Alt+X}
2.响应热键： private procedure WMHotKey(var Msg: TWMHotKey); message WM_HOTKEY; ... procedure TfrmAdKiller.WMHotKey(var Msg: TWMHotKey); begin if Msg.HotKey = 125 then begin if Visible then LoadAppIcon else UnLoadIcon; end; end; 3.FormDestroy中释放热键： UnregisterHotKey(Handle, 125);

                        }
                    }
                }
                return false;
            }
        }

        public void OnHotkey(int HotkeyID) //Ctrl+F
        {
            if (HotkeyID == Hotkey1)
            {
                MessageBox.Show("按了Ctrl+F");
            }
            else
            {
                this.Visible = false;
            }
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            Hotkey hotkey;
            hotkey = new Hotkey(this.Handle);
            Hotkey1 = hotkey.RegisterHotkey(System.Windows.Forms.Keys.F, Hotkey.KeyFlags.MOD_CONTROL);   //定义快键Ctrl+F
            hotkey.OnHotkey += new HotkeyEventHandler(OnHotkey);
        }
    }
}

试着弄了下，上面代码可以实现注册“Ctrl+F”为全局热键。不过只实现了基本功能。
