分享求TreeView绑定任意路径的方法
我想用TreeView来绑定任意路径，但不知道如何加载子节点，循环读出来的目录和文件都显示在根节点中。忘高手指点迷津！

解决啦，我在treeView的beforeExpand事件里写的，判断当前节点是否是目录，然后继续向下展开！

不会慢，关键看你的目录下的文件夹以及文件有多少，如果上万的话，那肯定会慢了，就是你手动在资源管理器中打开都会比较慢。

用递归的话，程序运行起来会不会很慢啊？

geoffe(),你用的2003还是2005。我怎么调不过去呢！有些属性我的2003里没有！

比如绑定我的电脑
那你用一个循环就可以了
根极点是硬盘，子节点是相应的文件夹
private void FillTree()
{
this.treeview1.Nodes.Clear();
TreeNode RootNode = new TreeNode(openDialog1.fileName)
TreeNode DriveNode;
string[] strDrivers = Environment.GetLogicalDrives();
foreach (string DriverName in strDrivers)
{
DriveNode = new TreeNode(DriverName);
DriveNode.Name = "" + DriverName;
DriveNode.Tag = false;
if (CheckISSubFolder(DriverName))
{
TreeNode tmpnode = new TreeNode("tmp");
DriveNode.Nodes.Add(tmpnode);
}
RootNode.Nodes.Add(DriveNode);
}
if (RootNode.Nodes.Count > 0)
RootNode.Expand();
this.sysTreeView.Nodes.Add(RootNode);
}
private bool CheckISSubFolder(string Path)
{
DirectoryInfo dir = new DirectoryInfo(Path);
if (!dir.Exists)
{
return false;
}
else
{
DirectoryInfo[] subDirs = dir.GetDirectories();
int i = 0;
foreach (DirectoryInfo subDir in subDirs)
{
if ((subDir.Attributes & FileAttributes.Hidden) != 0)
{
continue;
}
else
{
if (++i > 0)
return true;
}
}
return false;
}
}
private void GetSubDirectory(TreeNode ParentNode, string Path)
{
try
{
DirectoryInfo dir = new DirectoryInfo(Path);
DirectoryInfo[] subDirs = dir.GetDirectories();
TreeNode SubNode;
ParentNode.Nodes.RemoveAt(0);
foreach (DirectoryInfo subDir in subDirs)
{
if ((subDir.Attributes & FileAttributes.Hidden) != 0)
continue;
SubNode = new TreeNode(subDir.Name);
SubNode.Name = subDir.FullName;
SubNode.Tag = false;
if (CheckISSubFolder(subDir.FullName))
{
TreeNode tmpnode = new TreeNode("tmp");
SubNode.Nodes.Add(tmpnode);
}
ParentNode.ImageIndex = 1;
ParentNode.SelectedImageIndex = 0;
ParentNode.Nodes.Add(SubNode);
}
}
catch { }
}

我会搜索所有文件，可不知道怎么把它按文件夹的路径加到treeView里，生成树状结构!

我是在winform下用的，有没有简单点的，给我点算法的提示就行！
