C#小型资源管理器

 添加treeView 和 listView 两个控件

{
     public  class MyFile
    {
            public float FileLength { get; set; }//文件大小（KB）
            public string FileName { get; set; }//文件名
            public string FilePath { get; set; }//文件路径
            public string FileType { get; set; }//文件类型
        }

    }

主窗体的代码：

public partial class FrmMain : Form
    {
        public FrmMain()
        {
            InitializeComponent();
        }
        TreeNode tn; //定义一个节点
        private void FrmMain_Load(object sender, EventArgs e)
        {
            //检索计算机上的所有逻辑驱动器的驱动器名称。
            DriveInfo[] di = DriveInfo.GetDrives();
            foreach (DriveInfo item in di)
            {
                tn = new TreeNode(item.Name);
                tn.Tag = item.Name;
                tv01.Nodes.Add(tn);
            }
        }
        //单击绑定文件和文件夹信息
        private void tv01_AfterSelect(object sender, TreeViewEventArgs e)
        {
            TreeNode tn = tv01.SelectedNode;
            BingInfo(tn);
        }


        private void BingInfo(TreeNode tn)
        {
            //清空
            listView1.Items.Clear();
            //绑定子目录
            DirectoryInfo dic = new DirectoryInfo(tn.Tag.ToString());

                temp.Tag = item.FullName;
                tn.Nodes.Add(temp);
            }

            //获取目录下文件列表
            FileInfo[] fileinfo = dic.GetFiles();

            }
