在c#中将树视图列表导出到文本文件

Question

我有一个树视图，我想将树视图的父节点、子节点导出到 .txt 文件。但是当我导出 .txt 文件时，格式看起来很糟糕。 我找到了这个主题，但它对我没有帮助。还有其他方法吗？

Saving content of a treeview to a file and load it later

我想在 .txt 文件中喜欢这个

1. 主文件夹
   • 子文件夹
     • .docx 或 .zip 文件
     • .docx 或 .zip 文件 2
   • 子文件夹 2
     • .txt 文件

但在我的 .txt 文件中是这样的。

要在文本文件中写树视图，可以通过以下代码

    private void button1_Click(object sender, EventArgs e)
    {
        btnCreateTreeData();
    }

    private void btnCreateTreeData()
    {
        // create buffer for storing string data
        System.Text.StringBuilder buffer = new System.Text.StringBuilder();
        // loop through each of the treeview's root nodes
        foreach (TreeNode rootNode in treeView1.Nodes)
            // call recursive function
            BuildTreeString(rootNode,buffer);
        // write data to file
        System.IO.File.WriteAllText(@"D:\treeTest.txt", buffer.ToString());
    }

    private void BuildTreeString(TreeNode rootNode,System.Text.StringBuilder buffer)
    {
        buffer.Append(rootNode.Text);
        buffer.Append(Environment.NewLine);
        foreach (TreeNode childNode in rootNode.Nodes)
            BuildTreeString(childNode,buffer);
    }
