1.递归查找树状目录

复制代码 代码如下:

public partial class Form1 : Form

{

string path = @"F:学习文件";//递归查找树状目录

public Form1()

{递归查找树状目录

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

LoadTree(path);

}

public void LoadTree(string path, TreeNode node=null)

{

string[] dirs = Directory.GetDirectories(path);//获取子目录

foreach (string dir in dirs)

{

TreeNode node1 = new TreeNode(Path.GetFileName(dir));

//TreeNode node1 = new TreeNode(dir);//文件所有路径

if (node == null)

{

treeView1.Nodes.Add(node1);

}

else

{

node.Nodes.Add(node1);

}

if (Directory.GetDirectories(dir).Length > 0)

{

LoadTree(dir, node1);

}

}

}

}

}
