一、第一种方法：可以这样接收前端传入的jsonArray字符串到一个类的数组中，然后遍历该数组取值
这种方法需要创建PointConfig类

 class PointConfig{public string ptcrossing { get; set; }public string ptcrossingId { get; set; }public string camId { get; set; }public string pointid { get; set; }public string ptdirection { get; set; }public string ptGoSet { get; set; }public string ptGoEn { get; set; }public string ptLeftSet { get; set; }public string ptLeftEn { get; set; }public string ptRightSet { get; set; }public string ptRightEn { get; set; }public string ptname { get; set; }public string ptmainX { get; set; }public string ptmainY { get; set; }public string ptsubX { get; set; }public string ptsubY { get; set; }public string ptframediffX { get; set; }public string ptframediffY { get; set; }public string ptgreenlightX { get; set; }public string ptgreenlightY { get; set; }public string ptredlightX { get; set; }public string ptredlightY { get; set; }public string ptmainvalid { get; set; }public string ptsubvalid { get; set; }public string ptframediffvalid { get; set; }public string ptqueuelengthvalid { get; set; }public string ptcheckmethod { get; set; }public string ptchanneltypeA { get; set; }public string ptchanneltypeB { get; set; }public string cameraName { get; set; }public string xgr { get; set; }}
