C#仿WINDOWS可折叠导航栏
昨天晚上看见了个帖子，野比小王子在2楼留下下了版主的http://blog.csdn.net/bdmh/article/details/7549140 ，今天下午没事做，自己也搞了一下，效果 不怎么好（窗体中有5个panel控件，设置其中4个的DOCK属性为TOP，具体见源码）。废话不多说，代码如下：

C# code

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication2{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }              private Font ft = new Font("黑体",12);        private static Panel iPanel= new Panel();        private static PictureBox iPict =new PictureBox();        private void Form1_Load(object sender, EventArgs e)        {            pictureBox1.Image = global::WindowsFormsApplication2.Properties.Resources.朝上按钮;            pictureBox1.Size = global::WindowsFormsApplication2.Properties.Resources.朝上按钮.Size;            pictureBox2.Image = global::WindowsFormsApplication2.Properties.Resources.朝上按钮;            pictureBox2.Size = global::WindowsFormsApplication2.Properties.Resources.朝上按钮.Size;            ft = label1.Font;        }        private void label1_MouseEnter(object sender, EventArgs e)        {            ((Label)sender).ForeColor = Color.Red;//设置控件文字字颜色            ((Label)sender).Font = new Font(ft, ft.Style | FontStyle.Underline);//设置控件字体        }        private void label1_MouseLeave(object sender, EventArgs e)        {            ((Label)sender).ForeColor = Color.Black;//设置控件文字颜色            ((Label)sender).Font = new Font(ft, ft.Style); //设置控件字体        }        private void pictureBox1_Click(object sender, EventArgs e)        {            int i = Convert.ToInt16(((PictureBox)sender).Tag.ToString());            switch (i)            {                case 1:                    iPanel = panel2_1;                    iPict = pictureBox1;                    break;                case 2:                    iPanel = panel2_2;                    iPict = pictureBox2;                    break;            }            if (Convert.ToInt16(iPanel.Tag.ToString()) == 1)            {                iPanel.Tag = 2;                iPict.Image = Properties.Resources.朝上按钮;                iPanel.Visible = true;            }            else            {                iPanel.Tag = 1;                iPict.Image = Properties.Resources.朝下按钮;                iPanel.Visible = false;            }        }    }}
