c#[WebMethod]方法接收前端传入的JsonArray的方法

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; }
            }
