js给webApi传值List<DealBatchModel>

前台往webApi传值 传一个 List对象

前台代码var arr =                   {            "model": [             ]        }        for(var i=0;i<caseIdsArr.length;i++){            arr.model.push({"caseId": caseIdsArr[i],"StepKey": stepKeysArr[i],"actionId": "2F90F304-A57E-4647-96FC-3612988193CD","bookDate": BookDate,"bookTime": BookTime,"reschedule_remark": reschedule_remark});        }

后台代码（webAPI）public TResult DealCaseBatch(DealBatchparamModel deal)        {}        public class DealBatchparamModel : TokenBase    {        public List<DealBatchModel> model { get; set; }     }public class DealBatchModel    {        public string caseId { get; set; }        public string StepKey { get; set; }        public string actionId { get; set; }        public string JsonString { get; set; }    }
