1.递归查找树状目录
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);
}
}
}
}
