实现效果:

  用TreeView控件遍历磁盘目录-LMLPHP

知识运用:

  ListView控件中Items集合的Add方法  TteeView控件中Nodes集合的Add方法

实现代码:

        private void Form1_Load(object sender, EventArgs e)
{
TreeNode rootNode = new TreeNode("我的电脑");
treeView1.Nodes.Add(rootNode);
} private void ListViewShow(TreeNode NodeDir) {
listViewFile.Clear();
try
{
if (NodeDir.Parent == null)
{
foreach (string DrvName in Directory.GetLogicalDrives())
{
ListViewItem ItemList = new ListViewItem(DrvName);
listViewFile.Items.Add(ItemList);
}
}
else
{
foreach (string dirName in Directory.GetDirectories((string)NodeDir.Tag))
{
ListViewItem dirItem = new ListViewItem(dirName);
listViewFile.Items.Add(dirItem);
}
foreach (string fileName in Directory.GetFiles((string)NodeDir.Tag))
{
ListViewItem fileItem = new ListViewItem(fileName);
listViewFile.Items.Add(fileItem);
}
}
}
catch { }
} private void TreeViewShow(TreeNode selectNode) {
try {
if(selectNode.Nodes.Count==0){
if (selectNode.Parent == null)
{
foreach (string drvName in Directory.GetLogicalDrives())
{
TreeNode drvNode = new TreeNode(drvName);
drvNode.Tag = drvName;
selectNode.Nodes.Add(drvNode);
}
}
else {
foreach (string dirName in Directory.GetDirectories((string)selectNode.Tag))
{
TreeNode dirNode = new TreeNode(dirName);
dirNode.Tag = dirName;
selectNode.Nodes.Add(dirNode);
}
}
}
}catch(Exception ex){
MessageBox.Show(ex.Message);
}
} private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
TreeViewShow(e.Node);
ListViewShow(e.Node);
}
