没有找到解决以下问题的方法.
我有一个工作代码用于在文件中保存/加载TreeView但我想将它保存到Properties.Settings.Default.

不幸的是,我在这行中收到错误"没有对象的地图":

object obj = bf.Deserialize(ms);

这是(反)序列化的完整代码:
不知道如何解决这个问题.:(

public static void SaveTreeView(TreeView tree)
{
    using (MemoryStream ms = new MemoryStream())
    {
        BinaryFormatter bf = new BinaryFormatter();
        bf.Serialize(ms, tree.Nodes.Cast<TreeNode>().ToList());
        ms.Position = 0;
        var sr = new StreamReader(ms);
        Properties.Settings.Default.tree = sr.ReadToEnd();
        Properties.Settings.Default.Save();
    }
}

public static void LoadTreeView(TreeView tree)
{

    using (MemoryStream ms = new MemoryStream())
    {
        var sw = new StreamWriter(ms);
        sw.WriteLine(Properties.Settings.Default.tree);
        sw.Flush();
        ms.Seek(0, SeekOrigin.Begin);

        BinaryFormatter bf = new BinaryFormatter();
        object obj = bf.Deserialize(ms);

        TreeNode[] nodeList = (obj as IEnumerable<TreeNode>).ToArray(); …
