如何创建可序列化的动态模型？

Question

我正在尝试创建一个可以动态更改的可序列化模型

序列化后的JSon将如下所示

{
    "Job" : {
        "LensJobId" : "123546"
        "JobTitle"  : "Manager"
        "PostingDate" : "2013-11-20"
    }
    "Job" : {
        "LensJobId" : "3256987"
        "JobTitle"  : "Supervisor"
        "PostingDate" : "2013-11-20"
    }
}

我目前拥有的Serializable类

Class Job
{
  public string lensjobid {get; set;}
  public string jobtitle{get; set;}
  public string postingdate{get; set;}
}

现在的新要求是我必须包括在工作中的条目基于请求例如:如果请求lensjobid和jobtitle我必须包括这些，或者如果请求要求位置详细信息，如州，国家等，那么应该包括在内。

对于上述请求，我提出了如下解决方案

public class DistributionList : List<Distribution>
{

}

[DataContract]
public class Distribution
{   
    [DataMember(Name = "Job")]
    public List<KeyValuePair<string, string>> DistributionValues { get; set; }

}

的序列化json输出将是

  [{
            "Job" : [{
                    "Key" : "lensjobid",
                    "Value" : "124353453"
                }, {
                    "Key" : "JobTitle",
                    "Value" : "Manager"
                },
                {
                    "Key" : "PostingDate",
                    "Value" : "2012-13-11"
                }
            ]
        },
{
    "Job" : [{
                    "Key" : "lensjobid",
                    "Value" : "124353453"
                }, {
                    "Key" : "JobTitle",
                    "Value" : "Manager"
                },
                {
                    "Key" : "PostingDate",
                    "Value" : "2012-13-11"
                }
            ]
        }

    ]

但上面的结果对我来说很奇怪，有没有办法让它看起来像我之前方法的输出？

谢谢和问候！！

使用json.net并创建协定解析器

public class CustomContractResolver : Newtonsoft.Json.Serialization.DefaultContractResolver
{
    private IEnumerable<string> propertyNames;

    public CustomContractResolver(IEnumerable<string> propertyNames)
    {
        this.propertyNames = propertyNames;
    }
    protected override IList<JsonProperty> CreateProperties(Type type, Newtonsoft.Json.MemberSerialization memberSerialization)
    {
        var properties = base.CreateProperties(type, memberSerialization);
        return properties.Where(p => propertyNames.Contains(p.PropertyName)).ToList();
    }
}

像这样序列化

var jobs = getJobs();    
var contractResolver = new CustomContractResolver(new[]{ "Property1", "Property2" });

string json = Newtonsoft.Json.JsonConvert.SerializeObject(jobs, Newtonsoft.Json.Formatting.Indented,
    new Newtonsoft.Json.JsonSerializerSettings { ContractResolver = contractResolver });
