c#读写INI文件做历史信息菜单日志
读写INI文件的类

技巧1    address = System.Environment.CurrentDirectory;取得当前的目录

2 使用StreamWriter 类 写入

using System;
using System.IO;

class Test 
{
    public static void Main() 
    {
        //将数据写入TestFile.txt类中间
        using (StreamWriter sw = new StreamWriter("TestFile.txt")) 
        {
            
            sw.Write("This is the ");
            sw.WriteLine("header for the file.");
            sw.WriteLine("-------------------");
             
            sw.Write("The date is: ");
            sw.WriteLine(DateTime.Now);
        }
    }
}

使用StreamReader 类 读取

using System;
using System.IO;

class Test 
{
    public static void Main() 
    {
        try 
        {
            // Create an instance of StreamReader to read from a file.
            // The using statement also closes the StreamReader.
            using (StreamReader sr = new StreamReader("TestFile.txt")) 
            {
                String line;
                // Read and display lines from the file until the end of 
                // the file is reached.
                while ((line = sr.ReadLine()) != null) 
                {
                    Console.WriteLine(line);
                }
            }
        }
        catch (Exception e) 
        {
            // Let the user know what went wrong.
            Console.WriteLine("The file could not be read:");
            Console.WriteLine(e.Message);
        }
    }
}

使用 在MDIFROM LOAD的时候 读取INI文件

     private void Form1_Load(object sender, EventArgs e)
        {
            StreamReader sr = new StreamReader(address + "\\Menu.ini");
            int i = this.文件ToolStripMenuItem.DropDownItems.Count-2;
            while (sr.Peek()>=0)
            {
                ToolStripMenuItem menuitem = new ToolStripMenuItem(sr.ReadLine());
                this.文件ToolStripMenuItem.DropDownItems.Insert(i, menuitem);
                i++;
                menuitem.Click += new EventHandler(menuitem_Click);
            }
            sr.Close();
        }

每次打开的时候写入

      private void 打开ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            openFileDialog1.FileName = "";
            this.openFileDialog1.ShowDialog();
            StreamWriter s = new StreamWriter(address + "\\Menu.ini", true);
            s.WriteLine(openFileDialog1.FileName);
            s.Flush();
            s.Close();
             
            
        }

  这样就可以在每次开打的时候看到读取的历史文件了

如果在读取的时候加个限制 如果说10个文件以内，那么很简单只要在读取的时候循环加一个限制就OK
