C#中，我想在结点上点击鼠标右键获得该结点的路径，应该怎么写代码？谢谢!

下面是我以前写过的东西，希望能对你有所帮助


//处理TreeView中的事件
private void TreeView_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e)
{
DataSet ds = new DataSet();

SqlConnection conn = new SqlConnection("Data Source=localhost;Initial Catalog=student;Integrated Security=True");
switch (TreeView.SelectedNode.Name)
{
case "girl":
SqlDataAdapter daAuthors = new SqlDataAdapter("Select ID ,sno,sname,sex From student where sex=0", conn);
conn.Open();
daAuthors.Fill(ds, "student");

// conn.Close() '在填充完ds后关闭连接，接着对ds进行操作
dataGrid1.DataSource = ds.Tables[0];//vb.net上使用这样的语句：ds.Tables("student");
conn.Close();
break;

case "boy":

SqlDataAdapter daAuthor = new SqlDataAdapter("Select ID ,sno,sname,sex From student where sex=1", conn);
conn.Open();
daAuthor.Fill(ds, "student");

// conn.Close() '在填充完ds后关闭连接，接着对ds进行操作
dataGrid1.DataSource = ds.Tables[0];//vb.net上使用这样的语句：ds.Tables("student");

conn.Close();
break;

}

}

呵呵,谢谢,可是我还是不太懂,我没有用到数据库.就只是做了一个本机文件的treeView,现在就是想在结点上右击，弹出上下文菜单，获得被点击的结点的路径，以便对其进行一些别的操作．

public partial class Form1 : Form
{
private string nodeName;
public Form1()
{
InitializeComponent();
}

private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
contextMenuStrip1.Show(this, e.X, e.Y);
nodeName = e.Node.Name;
}
}

private void Form1_Load(object sender, EventArgs e)
{
DriveInfo[] drives = DriveInfo.GetDrives();
treeView1.PathSeparator = @"\";
foreach (DriveInfo drive in drives)
{
TreeNode parent=new TreeNode();
parent.Text = drive.Name;
parent.Name = drive.Name;
treeView1.Nodes.Add(parent);
}
}

private void menupath_Click(object sender, EventArgs e)
{
MessageBox.Show("你选择的节点路径为：" + nodeName);
}
}

就做了驱动器那一级目录
下面的子目录你自己遍历一下吧
基本要求实现了

恩,好方法,可是我对文件树的加载是这样进行的,以下是我的代码,怎么才能实现我的功能呢.

Zc.ZipFileMain(FileProperties);　　//函数的参数是文件的路径，现在的问题是怎么取的文件的路径
}
