C#中怎么用listview显示指定路径下的文件和文件夹~
比如我要显示D:\test\下的所有文件，最好也能显示图标~然后显示了之后还可以双击文件并且打开他~急求大神~本人初学C#不太懂网上写的什么Shell之类的~请大牛指教 --------------------编程问答-------------------- 用什么shell，不就是目录遍历吗http://jlj84237485.blog.163.com/blog/static/34929460201010401434877/ --------------------编程问答--------------------
List<ProgramInfo> ProInfo = new List<ProgramInfo>();
Microsoft.Win32.RegistryKey key = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Uninstall", false);
Microsoft.Win32.RegistryKey key2 = null;
string softwareName, installLocation, IconPath;
if (key != null)//判断对象存在
{
foreach (string keyName in key.GetSubKeyNames())//遍历子项名称的字符串数组
{
key2 = key.OpenSubKey(keyName, false);//遍历子项节点
if (key2 != null)
{
softwareName = key2.GetValue("DisplayName", "").ToString();//获取软件名
IconPath = key2.GetValue("DisplayIcon", "").ToString();//获取安装路径InstallLocation
installLocation = key2.GetValue("InstallLocation", "").ToString();
if (!string.IsNullOrEmpty(installLocation))
{
ProInfo.Add(new ProgramInfo()
{
ProName = softwareName,
ProPath = installLocation,
ProIconPath = IconPath
});
}
softwareName = "";
installLocation = "";
}
key2 = null;
}
}
for (int i = 0; i < ProInfo.Count; i++)
{
try
{
ProInfo[i].ProImage = System.Drawing.Icon.ExtractAssociatedIcon(ProInfo[i].ProIconPath);

安装程序图标获取和显示
private void BindDrives()
{
DriveInfo[] drvs = DriveInfo.GetDrives();
foreach (DriveInfo drv in drvs)
{
TreeNode root = new TreeNode();
root.Text = drv.Name;
root.Tag = drv.RootDirectory.ToString();
// root.Nodes.Add("");
treeView1.Nodes.Add(root);
if (Directory.Exists(drv.RootDirectory.ToString()))
{
DirectoryInfo dInfo = new DirectoryInfo(drv.RootDirectory.ToString());
FileSystemInfo[] files = dInfo.GetFileSystemInfos();
if (files.Length > 0) //有子节点，先添加一个空节点
{
root.Nodes.Add("emptyNode", string.Empty);
}
}
}
}
//展开节点，移除以前的空节点，加载子节点
private void treeView1_AfterExpand(object sender, TreeViewEventArgs e)
{
TreeNode parentNode = e.Node;
// parentNode.Nodes.RemoveByKey("emptyNode");//移除空节点
parentNode.Nodes.Clear();
string path = parentNode.Tag.ToString();
if (Directory.Exists(path))
{
DirectoryInfo dir = new DirectoryInfo(path);
FileSystemInfo[] files = dir.GetFileSystemInfos();
foreach (FileSystemInfo f in files)
{
TreeNode node = new TreeNode();
node.Text = f.Name;
node.Tag = f.FullName;
parentNode.Nodes.Add(node); //加载子节点
if (Directory.Exists(node.Tag.ToString()))
{
DirectoryInfo subDir = new DirectoryInfo(node.Tag.ToString());
if (subDir.Attributes != (FileAttributes.System | FileAttributes.Hidden | FileAttributes.Directory))
{
FileSystemInfo[] subFiles = null;
try
{
subFiles = subDir.GetFileSystemInfos();
}
catch { continue; }
if (subFiles.Length > 0) //有子节点，先添加一个空节点
{
node.Nodes.Add("emptyNode", string.Empty);
}
}
}
}
}
}
目录树形结构显示。
路径知道了。。。打开文件就不用说了哈 --------------------编程问答--------------------
用listview显示~ --------------------编程问答--------------------
。。。用listview就是不行了么？这里只告诉方法
不帮忙写代码的
补充：.NET技术 , C#
