C#
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。
(1)新建 windows 应用程序。
(2)将窗体 Form 的 Text 属性设置为“简易的文件管理器”。
(3)窗体上添加 SplitContainer、TreeView、ListView 控件，设置属性。将 TreeView 控
件的 Dock 属性设置为 Left，ListView 控件的 Dock 属性设置为 Fill,MultiSelect 属性设置为False，View 属性设置为 List。
(4)在 Form1.cs 中，添加对命名空间 using System.IO 的引用。
(5)在 Form1 的构造函数中添加代码：
public Form1()
{
InitializeComponent();
TreeNodemyComputerNode = new TreeNode("我的电脑"); treeView1.Nodes.Add(myComputerNode); listViewShow(myComputerNode);
}
(6)编写 ListView 控件的方法 listViewShow(TreeNodedirNode)。
private void listViewShow(TreeNodedirNode)
{
listView1.Clear();
if (dirNode.Parent == null)
{
foreach (string DrvName in Directory.GetLogicalDrives())
{
ListViewItemaItem = new ListViewItem(DrvName);
listView1.Items.Add(aItem);
}
}
else
{
foreach (string DirName in Directory.GetDirectories((string)dirNode.Tag))
{
ListViewItemaItem = new ListViewItem(DirName);
listView1.Items.Add(aItem);
}
foreach (string fileName in Directory.GetFiles((string) dirNode.Tag))
{
ListViewItemaItem=new ListViewItem(fileName);
listView1.Items.Add(aItem);
}
}
}
(7)编写 listViewShow 的重载方法。
private void listViewShow(string dirName)
{
listView1.Clear();
try
{
foreach (string DirName in Directory.GetDirectories(dirName))
{
ListViewItemaItem = new ListViewItem(DirName);
listView1.Items.Add(aItem);
}
foreach (string fileName in Directory.GetFiles(dirName))
{
ListViewItemaItem = new ListViewItem(fileName);
listView1.Items.Add(aItem);
}
}
catch
{
}
}
(8)编写 DirTreeShow(TreeNodedirNode)方法。
private void DirTreeShow(TreeNodedirNode)
{
try
{
if (dirNode.Nodes.Count == 0)
{
if (dirNode.Parent == null)
{
foreach (string DrvName in Directory.GetLogicalDrives())
{
TreeNodeaNode= new TreeNode(DrvName);
aNode.Tag=DrvName;
dirNode.Nodes.Add(aNode);
}
}
else
{
foreach(string DirName in Directory.GetDirectories((string)dirNode.Tag))
{
TreeNodeaNode=new TreeNode(DirName);
aNode.Tag=DirName;
dirNode.Nodes.Add(aNode);
}
}
}
}
Catch
{
}
}
(9)编写 TreeView 控件的 AfterSelect 事件代码。
private void treeView1_AfterSelect_1(object sender, TreeViewEventArgs e)
{
listViewShow(e.Node);
DirTreeShow(e.Node);
}
(10)编写 ListView 控件的 DoubleClick 事件代码。
private void listView1_DoubleClick(object sender, EventArgs e)
{
foreach (int listIndex in listView1.SelectedIndices)
{
listViewShow(listView1.Items[listIndex].Text);
}
}
(11)单击启动调试工具，运行结果参见下图。

{
partial class Form1
{
private System.ComponentModel.IContainer components = null;
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
