带历史信息的菜单

注：要建立一个带历史信息的菜单，将主窗体设置为父窗体。并将在菜单中最近打开文件的文件名和路径保存到事先建立的*.ini文件中。

 

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;using System.IO;

namespace MenuHistory1{    public partial class frmMenuHistory : Form    {        string adress;        public frmMenuHistory()        {            InitializeComponent();

            //获取或设置当前工作目录的完全限定路径

            adress = System.Environment.CurrentDirectory;        

        }

        /// <summary>        /// 将打开的文件路径写入INI文件       

        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void tsmiOpen_Click(object sender, EventArgs e)        {            this.openFileDialog1.ShowDialog();            StreamWriter sw = new StreamWriter(adress + "\\menu.ini", true);            sw.WriteLine(openFileDialog1.FileName); //写入INI文件            sw.Flush();            sw.Close();            ShowWindows(openFileDialog1.FileName);        }

        /// <summary>        /// 读取INI文件并将信息加入菜单的实现代码        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void frmMenuHistory_Load(object sender, EventArgs e)        {            StreamReader sr = new StreamReader(adress + "\\menu.ini");            int i = this.tsmiFile.DropDownItems.Count - 2;            while (sr.Peek() > 0)            {                ToolStripMenuItem menuitem = new ToolStripMenuItem(sr.ReadLine());                this.tsmiFile.DropDownItems.Insert(i, menuitem);                i++;                menuitem.Click += new EventHandler(menuitem_Click); //表示将处理不包含事件数据的事件的方法。            }        }

        private void menuitem_Click(object sender, EventArgs e)        {            ToolStripMenuItem menu = (ToolStripMenuItem)sender;            ShowWindows(menu.Text);        }

        /// <summary>        /// 用来加载背景图片并显示窗体的自定义方法。        /// </summary>        /// <param name="fileName"></param>        private void ShowWindows(string fileName)        {            Image pic = Image.FromFile(fileName);            Form f = new Form();            f.MdiParent = this;            f.BackgroundImage = pic;            f.Show();        }

        private void tsmiExit_Click(object sender, EventArgs e)        {            Application.Exit();        }

    }}
