C#学习5

今天继续C#的学习，今天的目标是完成一个简易的文件管理装置 具体要求如下

1．编写一个简易的文件管理器，通过本次实验，练习 TreeView、ListView 和

SplitContainer 控件的使用，同时熟悉 C#文件系统的操作方法以及 File 类和 Directory类的使用。 

界面设计：
partial class Form1
    {
        /// <summary>
        ///  Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        ///  Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        ///  the contents of this method with the code editor.
