使用Newtonsoft Json.NET这很容易实现：

// Your main code...
String path = @"C:\Data\";
DirectoryInfo di = new DirectoryInfo(path);
String json = GetJsonDirectoryStructure(di).ToString();

// Method implementation...
public static JObject GetJsonDirectoryStructure(DirectoryInfo di)
{
    JObject jObj = new JObject();

    foreach (DirectoryInfo diChild in di.GetDirectories())
        jObj.Add(diChild.Name, GetJsonDirectoryStructure(diChild));

    foreach (FileInfo di in di.GetFiles())
        jObj.Add(fi.Name, JValue.CreateNull());

    return jObj;
}
