如何从json访问动态密钥和值到wcf [英] how to access dynamic key and value from json to wcf

问题描述

大家好，





我从json传递requeset到wcf服务除了scoredata参数值之外我得到的所有参数值是动态的。请帮助我解决我的问题。



Json请求





{ProspectNo：1000000073，MakerId：C136771，MkrDate：2015/11/26，TranID：null，ScoreData：{客户体验：1，稳定性和所有权：7，财产所有权：22，共同申请/担保人：16，建议成本：1800000}}

  public   class 得分
 {
 
 [DataMember（）] 
  public   string  ProspectNo; 
 
 [DataMember（）] 
  public   string  MakerId; 
 
 [DataMember（）] 
  public   string  MkrDate; 
 
 
 [DataMember（）] 
  public   string  TranID; 
 
 [DataMember（）] 
  public  Dictionary< string，string> ScoreData; 
} 

MakerId =C136771

MkrDate =2015/11/26

ProspectNo =1000000073

ScoreData = Count = 0

解决方案

这是因为JSON（de）序列化程序正在寻找一个数组并且得到一个对象。



您可以通过以下两种方式解决此问题;第一个（也是最简单的）是更改ScoreData的类型以更恰当地反映传入的数据：

 [DataMember（）] 
  public   object  ScoreData; 

当你需要阅读时，你可以使用动态。



另一条路线是纠正JSON即将投入使用。更正后的JSON如下所示：

 {  ProspectNo ：  1000000073，  MakerId：  C136771，  MkrDate： < span class =code-string> 2015/11/26，  TranID： null ，  ScoreData： [{ 密钥： < span class =code-string>客户体验， 值：< span class =code-string>  1}，{  Key ： 稳定性&所有权， 值，   7}，{  Key ： 属性所有权， 值：  22}，{ 键：  Co-app / Guarantor，  Value：  16}，{ 密钥： 建议成本，  Va lue：  1800000}]} 

Hi all,


I am passsing requeset from json to wcf service all the parameter value i get except scoredata parameter value which is dynamic. pls help me to solve my problem.

Json Request


{"ProspectNo":"1000000073","MakerId":"C136771","MkrDate":"2015/11/26","TranID":null,"ScoreData":{"Client Experience":"1","Stability & Ownership":"7","Property ownership":"22","Co-app/Guarantor":"16","proposed cost":"1800000"}}

public class Score
{

    [DataMember()]
    public string ProspectNo;

    [DataMember()]
    public string MakerId;

    [DataMember()]
    public string MkrDate;

  
    [DataMember()]
    public string TranID;

    [DataMember()]
   public Dictionary<string, string> ScoreData;
}

MakerId = "C136771"
MkrDate = "2015/11/26"
ProspectNo = "1000000073"
ScoreData = Count = 0

解决方案

That's because the JSON (de)serializer is looking for an array and is getting an object.

You can solve this in one of two ways; the first (and easiest) is to change the type of ScoreData to more appropriately reflect the incoming data:

[DataMember()]
   public object ScoreData;

You can then use "as dynamic" when you need to read from it.

The other route would be to correct the JSON that is coming into the service. The corrected JSON would look like:

{"ProspectNo":"1000000073","MakerId":"C136771","MkrDate":"2015/11/26","TranID":null,"ScoreData":[{ "Key": "Client Experience", "Value": "1"},{ "Key": "Stability & Ownership", "Value" ,"7"},{"Key": "Property ownership", "Value": "22"},{"Key": "Co-app/Guarantor", "Value":"16"},{ "Key": "proposed cost", "Value":"1800000"}]}
