在 GridView（Windows 表单）中显示 XML 内容

Question

我一直试图在 Windows 表单的 gridview 中显示所选 xml 文件的所有内容，但由于某种原因，只显示第一个父节点的内容（播放列表).我找不到解决方案。

这是我的代码：

private void OpenMontagem_btn(object sender, EventArgs e)
    {
        var fileContent = string.Empty;
        var filePath = string.Empty;

        using (OpenFileDialog openFileDialog = new OpenFileDialog())
        {
            openFileDialog.InitialDirectory = @"C:\Playlist\pgm\Montagem\";
            openFileDialog.Filter = "xml files (*.xml)|*.xml|All files (*.*)|*.*";

            if (openFileDialog.ShowDialog() == DialogResult.OK)
            {
                filePath = openFileDialog.FileName;

                var fileStream = openFileDialog.OpenFile();

                using (StreamReader reader = new StreamReader(fileStream))
                {
                    fileContent = reader.ReadToEnd();
                }
            }
        }

        using (DataSet ds = new DataSet())
        {
            ds.ReadXml(filePath);
            MontagemGrid.DataSource = ds.Tables[0];
        }
    }

这是 xml 文件的一部分

如果我将 ds.Tables[0] 更改为 ds.Tables[1]，它会显示名称为 Ins0

的每个节点

有没有办法在 gridview 中构建和显示每一点内容？
