Json to JObject转换的使用方法

类名	说明
JObject	用于操作JSON对象
JArray	用语操作JSON数组
JValue	表示数组中的值
JProperty	表示对象中的属性,以"key/value"形式
JToken	用于存放Linq to JSON查询后的结果

使用Linq to JSON

1.查询
首先准备Json字符串，是一个包含员工基本信息的Json

string json = "{"Name" : "Jack", "Age" : 34, "Colleagues" : [{"Name" : "Tom" , "Age":44},{"Name" : "Abel","Age":29}] }";

//将json转换为JObject
            JObject jObj = JObject.Parse(json);
            //通过属性名或者索引来访问，仅仅是自己的属性名，而不是所有的
            JToken ageToken =  jObj["Age"];
            Console.WriteLine(ageToken.ToString());

②获取该员工同事的所有姓名

//将json转换为JObject
            JObject jObj = JObject.Parse(json);
            var names=from staff in jObj["Colleagues"].Children()
                             select (string)staff["Name"];
            foreach (var name in names)
                Console.WriteLine(name);
"Children()"可以返回所有数组中的对象

增加几个平常用到的实例

// 一个JAarry 数组的类型
[{"SKU":"001X","SN":""},{"SKU":"00020","SN":""},{"SKU":"00099","SN":""},{"SKU":"7-M03910","SN":"049E"}]
 var skus = new JArray(items.Select(l => new JObject
                    {
                        new JProperty("Sku", l.Element("itemCode").Value),
                        new JProperty("SN",l.Element("serialNo").Value),
                    }));

                    var obj = new JObject
                           {
                              {"Head", new JObject
                                        {
                                              { "TransId", transid },
                                              { "TransCode", "X1008" }
                                        }
                              },
                              {"Body", new JObject
                                    {
                                        { "OrderSN", code1 },
                                        { "ERPNo", code2 },
                                        { "DeliveryNumber", code3 },
                                        { "DeliveryDateTime", code4 },
                                        { "SNs", skus }//这里没有层级关系
                                    }
                              }
                            };

构造层级的JObject

var Orderline = new JArray(so.body.detail.Select(l => new JObject
                          {
                            new JProperty("itemCode", l.PartNo),
                            new JProperty("itemId", ""),
                            new JProperty("planQty", l.GoodsNumber)

                          }));

//封装xml
                var obj = new JObject
                    {
                        {"?xml",new JObject{
                                {"@version","1.0" },
                                {"@encoding","utf-8"}}
                        },
                        { "request", new JObject{
                                {"deliveryOrder", new JObject
                                    {
                                        {"订单号",so.body.OrderSN },
                                        {"订单类型","XSDD" },

                                             new JObject{

                                                        }
