C# 打字游戏 给个连击！

Question

做个打字游戏  如果连续输出正确则 连击++；但是就是不会判断 下面是按下事件
        private void Form1_KeyDown(object sender, KeyEventArgs e)
        {
            kysdown++;//记录按下
            Keys s = e.KeyCode;
            foreach (Control c in this.panel1.Controls)//便利出lable
            { if (c.Text == s.ToString())
                {
                    zheng++;//如果相等则正确计数
                   this.lblzheng.Text = "正确:" + zheng.ToString();
                    timer2.Start();
                    tmrG.Start();
                    this.panel2.Controls.Clear();
                }如果给后面打上else{ 在这里判断}  根本不行···如果正确  lianji++ 否则  lianji=0;这个否则该往哪里写？ 注意些在这段代码后面根本不行！

钩子:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        IntPtr CurrHook;        //得到钩子句柄        
        [DllImport("kernel32.dll")]
        public static extern int GetCurrentThreadId();      //得到线程ID        [DllImport("user32.dll")]
        //--------开始装钩子HookType:钩子类型,backCall:回调委托,MyNull:当前实例句柄,ThreadId:线程ID
        public static extern IntPtr SetWindowsHookEx(int HookType, KeyBackCall backCall, IntPtr MyNull, int ThreadId);        [DllImport("user32.dll")]
        public static extern IntPtr CallNextHookEx(IntPtr CurrHook, int nCode, IntPtr wParam, IntPtr lParam);
        [DllImport("user32.dll")]
        public static extern void UnhookWindowsHookEx(IntPtr CurrHook);        //----回调的委托
        public delegate IntPtr KeyBackCall(int nCode, IntPtr wParam, IntPtr lParam);        //--------委托事件
        public IntPtr KeyBackCallEvent(int nCode, IntPtr wParam, IntPtr lParam)
        {
            if (nCode > 0)
            {
                MessageBox.Show(wParam.ToString());
                return CallNextHookEx(CurrHook, nCode, wParam, lParam);
            }
            return CallNextHookEx(CurrHook, nCode, wParam, lParam);
        }
        private void button1_Click(object sender, EventArgs e)
        {
            CurrHook = SetWindowsHookEx(2, new KeyBackCall(KeyBackCallEvent), IntPtr.Zero, GetCurrentThreadId());           
            
        }         private void button2_Click(object sender, EventArgs e)
        {
            UnhookWindowsHookEx(CurrHook);        }

代码通过测试:using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        IntPtr CurrHook;        //得到钩子句柄
        [DllImport("kernel32.dll")]
        public static extern int GetCurrentThreadId();      //得到线程ID        [DllImport("user32.dll")]
        //--------开始装钩子HookType:钩子类型,backCall:回调委托,MyNull:当前实例句柄,ThreadId:线程ID
        public static extern IntPtr SetWindowsHookEx(int HookType, KeyBackCall backCall, IntPtr MyNull, int ThreadId);        [DllImport("user32.dll")]
        public static extern IntPtr CallNextHookEx(IntPtr CurrHook, int nCode, IntPtr wParam, IntPtr lParam);
        [DllImport("user32.dll")]
        public static extern void UnhookWindowsHookEx(IntPtr CurrHook);
        //----回调的委托
        public delegate IntPtr KeyBackCall(int nCode, IntPtr wParam, IntPtr lParam);        //--------委托事件
        public IntPtr KeyBackCallEvent(int nCode, IntPtr wParam, IntPtr lParam)
        {
            if (nCode > 0)
            {
                MessageBox.Show(wParam.ToString());//这里得到字符asc码
                return CallNextHookEx(CurrHook, nCode, wParam, lParam);
            }
            return CallNextHookEx(CurrHook, nCode, wParam, lParam);
        }
        private void button1_Click(object sender, EventArgs e)
        {
            CurrHook = SetWindowsHookEx(2, new KeyBackCall(KeyBackCallEvent), IntPtr.Zero, GetCurrentThreadId());        }
        private void button2_Click(object sender, EventArgs e)
        {
            UnhookWindowsHookEx(CurrHook);        }
    }
