Four main operation classes: JsonConverter, JsonHelper, JsonSplit and AjaxResult
1. JsonConverter:
Custom query object conversion to dynamic class, object dynamic class conversion to json package, json conversion to object dynamic class, DataReader conversion to Json, DataSet conversion to Json, DataTable conversion to Json, Datatable conversion to Json, formatted character type date type Boolean type, filtering special characters, etc.
