Generates a JSON string code for the tree structure.

The framework uses EF6.0. You can use Newtonsoft.Json.dll (Baidu Search) for the returned value to serialize the returned value to a Json string, if the following value is used Jsonconvert.serializeobject ( Functiontree), don't say anything, on the instance code

The structure returned is as follows
