请教如何将以下的json格式转为DataTable ？
{"result": {"total_results": 7, "car_lists": [{"model_2": "CM2_05", "plate_number": "\u95fdCRA262", "expected_flow": "", "driver_gender": "", "description": "", "locate_status": 1, "model_3": "", "located_time": "", "driver_id_number": "", "volume": "", "width": "", "length": 4.2000000000000002, "driver_name": "\u5f90", "model_1": "CM1_01", "location": "", "tonnage": 11.0, "locate_number": "13850754219", "height": "", "model_4": ""}, {"model_2": "CM2_13", "plate_number": "\u5409A12311", "expected_flow": "\u4e0a\u6d77\u5e02,\u676d\u5dde\u5e02,\u6d4e\u5357\u5e02", "driver_gender": "", "description": "fddsfs", "locate_status": 0, "model_3": "", "located_time": "", "driver_id_number": "", "volume": "", "width": "", "length": 12.0, "driver_name": "13fsdfsd", "model_1": "CM1_16", "location": "", "tonnage": 111.0, "locate_number": "15659826026", "height": "", "model_4": ""}], "register_contact_number": "13850754219"}, "success": true}

我要的是car_lists中的数据:如model_2,plate_number,expected_flow等字段

去下载Newtonsoft.Json.dll，解析json然后自己填充到datatable
