c# - 在 JSON 中保存目录路径？

Question

我有一个显示文件夹 TreeView 的应用程序，格式如下:

- Main Folder
    - SubFolder
    - SubFolder
        - SubFolder
    - SubFolder

问题: 1) How do I search for all the folders (not files) and add them to a List called syncDirectories (已修复)

2) How would I then iterate through my JSON object and save it back to List<SavedData> in order to add/remove data (已修复)

3) How would I loop through my syncDirectories List and add all the nodes to the TreeView in WPF. (Keep in mind the treeview with checkbox class i am using.

等等。另外，这是一个演示格式的例子，用户可以有更多的子目录。

由于这个 TREEVIEW CLASS.，这些文件夹中的每一个都有一个复选框

为了保存用户添加(和检查)的所有文件夹和子文件夹，我认为保存一个列出所有文件夹和子文件夹路径及其(真/假)检查值的 JSON 文件是个好主意。正确的？我正在使用 Json.NET。

我研究了一些 JSON，想出了这种格式:

{   
    "path": "path/here",
    "subDirectories": [
        {"path": "sub/path/here","sync": false},
        {"path": "sub/path/here","sync": true},
        {"path": "sub/path/here","sync": false}
    ]
}

其中翻译成类:

public class SavedData
{
    public string path { get; set; }
    public List<SubDirectory> subDirectories { get; set; }
}

public class SubDirectory
{
    public string path { get; set; }
    public bool sync { get; set; }
    public List<SubDirectory> subDirectories { get; set; }
}

这提出了一个问题，我如何搜索所有文件夹(不是文件)并将它们添加到 List称为 syncDirectories ？

这是我目前在 addDirectory 中的内容功能:

private void addDirectory()
{
    var dialog = new FolderBrowserDialog();
    DialogResult result = dialog.ShowDialog();
    if (result == System.Windows.Forms.DialogResult.OK)
    {
        SavedData data = new SavedData();
        data.path = dialog.SelectedPath;
        syncedDirectories.Add();
    }
    // Add the data to syncedDirectories List, then save the list and refresh the treeView
    saveData();
}

保存函数:

    public void saveData()
    {
        JsonSerializer serializer = new JsonSerializer();
        using (StreamWriter sw = new StreamWriter(appData))
        using (JsonWriter writer = new JsonTextWriter(sw))
        {
            serializer.Serialize(writer, syncedDirectories);
        }
    }

当我将数据保存到文件中时，我将如何遍历我的 JSON 对象并将其保存回 List<SavedData>为了添加/删除数据？

我已经弄清楚如何处理我的数据(如下)，但我该如何将这些“节点”添加到 TreeView 中呢？

    public void getDirectories(string dir)
    {
        // Create the Data Object
        SavedData data = new SavedData();
        data.path = dir;
        data.subDirectories = new List<SubDirectory>();
        foreach (string directory in Directory.GetDirectories(dir))
        {
            SubDirectory subDir = new SubDirectory();
            subDir.path = directory;
            subDir.subDirectories = getSubDir(directory);
            data.subDirectories.Add(subDir);
        }
        syncedDirectories.Add(data);
    }

    private List<SubDirectory> getSubDir(string dir)
    {
        List<SubDirectory> dataList = new List<SubDirectory>();
        SubDirectory subDir = new SubDirectory();
        foreach (string directory in Directory.GetDirectories(dir))
        {
            subDir.path = directory;
            subDir.subDirectories = new List<SubDirectory>();
            subDir.subDirectories = getSubDir(directory);
            dataList.Add(subDir);
        }
        return dataList;
    }

以后打算把这个程序开源到GitHub上。当我这样做时，我会在此处发布链接。

在研究了一个函数几个小时后，我意识到需要两个函数才能完成这个任务。

    public void getDirectories(string dir)
    {
        // Create the Data Object
        SavedData data = new SavedData();
        data.path = dir;
        data.subDirectories = new List<SubDirectory>();
        foreach (string directory in Directory.GetDirectories(dir))
        {
            SubDirectory subDir = new SubDirectory();
            subDir.path = directory;
            subDir.subDirectories = getSubDir(directory);
            data.subDirectories.Add(subDir);
        }
        syncedDirectories.Add(data);
    }

    private List<SubDirectory> getSubDir(string dir)
    {
        List<SubDirectory> dataList = new List<SubDirectory>();
        SubDirectory subDir = new SubDirectory();
        foreach (string directory in Directory.GetDirectories(dir))
        {
            subDir.path = directory;
            subDir.subDirectories = new List<SubDirectory>();
            subDir.subDirectories = getSubDir(directory);
            dataList.Add(subDir);
        }
        return dataList;
    }

这会获取主目录，然后循环查找所有子目录并将它们添加到我的列表中。
