JSON格式為:

{'CreateUnit':'測試部','CreateDeptID':'10034','CreateDate':'2012-12-05 18:31:00.000',
'HappenUnit':'開發部','HappenDeptID':'10034','HappenDate':'2012-12-04 18:56:00.000',
'ImpInfoSys':'dddd','PromoInfoSys':'ddd','STimeStart':'2012-12-04 18:57:00.000',
'STimeEnd':'2012-12-04 18:57:00.000','NonSTimeStart':'2012-12-04 18:57:00.000','NonSTimeEnd':'2012-12-04 18:57:00.000',
'Incidence':'10235','Reason':'ffff','Detail':'fff','CreaterTel':'dddfff','Remark':'dd','Creater':'owiewow'}

說明：EmergencyJson為字段名，JsonHelper為解析單位
