推荐答案

从OpenFileDialog.FileName属性中获取文件名，并使用string.Split将其分解为它带有反斜杠字符的组件文件夹。



然后循环遍历数组中的每个字符串Split返回，为每个字符串创建一个新节点并将其添加到前一个Nodes属性中一个。

Get the file name from the OpenFileDialog.FileName property, and use string.Split to break it into it's component folders with the backslash character.

Then loop through each string in the array Split returns, creating a new node for each and add it into the Nodes property of the previous one.

OpenFileDialog ofd = new OpenFileDialog();
if (ofd.ShowDialog() == DialogResult.OK)
    {
    string[] parts = ofd.FileName.Split('\\');
    TreeNodeCollection previousNodes = myTreeView.Nodes;
    foreach (string part in parts)
        {
        TreeNode node = new TreeNode(part);
        previousNodes.Add(node);
        previousNodes = node.Nodes;
        }
    myTreeView.ExpandAll();
    }
