过滤Json响应

Question

我有返回XML的API，我正在将结果映射到可以正常工作的自定义模型，并将结果转换为Json响应。
我需要根据规则集过滤Json响应并删除相关的响应节点。例如，如果“日期”大于5年或“类型”：“ F”，则需要删除“响应”节点，而仅保留相关的响应节点。

全结果：

我需要删除它：

                    "Info": {
                        "Number": "1",
                        "Date": "2013-03-01"
                    },
                    "CInfo": {
                        "Id": "1111",
                        "Type": "F"
                    },
                    "Subject": {
                        "Role": "CT",
                        "SNumber": "1"

                    },


                }
            }```




ant return this:


```{
    "Message": "True",
    "APIResponse": {
        "SearchedSubject": {
            "RequestSubject": {
                "Title": "",

                "Surname": "Blog",
                "DateOfBirth": "19720804T00:00:00",
