js給webApi傳值List

前臺往webApi傳值 傳一個 List對象

前臺代碼
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});
        }

後臺代碼（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; }
    }
