我的任务
分享读取任意 文件目录，生成 json格式！
要求实现给一个磁实现盘路径，读出 磁盘的文件夹、文件名称，生存树形结构，
我目前的思路是 循环读取 生存json字符串， 已经实现部分， 多文件夹嵌套级别 我仍然没有实现
提供我现在的代码
int id=1;
int subId=1;
StringBuilder jsonStr=new StringBuilder();
Dictionary<string, int> pIdWith=new Dictionary<string, int>();
public string InitTree(string sourceFolder, int no)
{
string[] subPaths=Directory.GetDirectories(sourceFolder);//得到所有子目录
foreach( string path in subPaths )
{
jsonStr.Append("{ \"id\":\""+id+"\",\"pId\":\"0\",\"name\":\""+path.Replace(sourceFolder+"\\", "")+"\"},");
subId+=10001;
InitTree(path, id);
}
string[] files=Directory.GetFiles(sourceFolder);
foreach( string file in files )
{
subId++;
jsonStr.Append("{ \"id\":\""+subId+"\",\"pId\":\""+id+"\",\"name\":\""+file.Replace(sourceFolder+"\\", "")+"\",\"url\":\""+file+"\"},");
}
id++;
return jsonStr.ToString();
}

1、定义树型json
2、递归文件填充

谢谢大伙的帮助，
我想要的格式就是 有个层级关系的 rutu如图

兄弟， 要不你试试，我写了一天了，都没折腾出来，还是不正确，如果多文件夹目录我的递归就乱套了，写不出来

你生存的json 不是我想要的，我需要 得到 父级 的id 刚好与前台ztree 无缝对接！

兄弟，目录结构的同时还有文件名的读取！我代码写不出来，脑袋比较笨拙、求源代码、

自定义一个树形结构
class TreeNode
{
public int nodeid;
public string nodename;
public TreeNode parentNode;
}
然后读取磁盘路径，动态递归构造List<TreeNode>结构。
最后通过序列化工具序列化成json即可。
