c# - 如何在 C# 中使用动态嵌套 JSON 文档

Question

我有一个嵌套的动态 JSON 模板文档，我需要对其进行反序列化并向其插入值以生成其中包含值的 JSON 内容。我有一个非嵌套 JSON 的工作逻辑，但我不确定如何制作适用于嵌套文档的逻辑（递归或其他更简单的方法，如果有的话）。

示例 JSON 模板

{
"LoanDate": [
    "Test"
],
"borrowerdetail": [
    {
        "borrowid": [
            "Test"
        ],
        "Name": [
            "Test"
        ],
        "Type": [
            "Test"
        ],
        "Status": [
            "Test"
        ]
    }
],
"loans": [
    {
        "bibdetails": [
            {
                "id": [
                    "Test"
                ],
                "title": [
                    "Test"
                ],
                "author": [
                    "Test",
                    "Test"
                ]
            }
        ],
        "Collection": [
            "Test"
        ],
        "ItemType": [
            "Test"
        ],
        "ItemNo": [
            "Test"
        ]
    }
],
"LoansItemBib": [
    "Test"
],
"LoansItem": [
    "Test"
]
}

当前逻辑

JavaScriptSerializer _objSolrDeserialized = new JavaScriptSerializer();
SolrResultTemp = "{";
dynamic SolrTempObject = _objSolrDeserialized.Deserialize<dynamic>(SolrResultTemp);
string Serialized = _objSolrDeserialized.Serialize(SolrTempObject);
int _iParentCount = 0;
foreach (var ObjSolr in SolrTempObject)
{
    var Type = ObjSolr.Value.GetType();
    if (Type.Name == "String")
    {
        string Value = ObjSolr.Value.Replace("$", "").Replace("^", "");
        List<string> ResString = ReturnConciseValEntry(Value, null, db2, FullTextPath, null, null);
        if (ResString.Count > 0)
        {
            foreach (var Res in ResString)
            {
                if (_iParentCount > 0)
                    SolrResultTemp = SolrResultTemp + ",";
                SolrResultTemp = SolrResultTemp + "\"" + ObjSolr.Key + "\": \"" + Res + "\"";
                _iParentCount += 1;
            }
        }
    }
    if (Type.Name == "Object[]")
    {
        string Key = ObjSolr.Key;
        List<string> _lstValue = new List<string>();
        foreach (var x in ObjSolr.Value)
        {
            string Value = x.Replace("$", "").Replace("^", "");
            List<string> ResString = ReturnConciseValEntry(Value, null, db2, FullTextPath, null, null);
            if (ResString.Count > 0)
                _lstValue.AddRange(ResString);
        }
        if (_lstValue.Count > 0)
        {
            if (_iParentCount > 0)
                SolrResultTemp = SolrResultTemp + ",";
            SolrResultTemp = SolrResultTemp + "\"" + ObjSolr.Key + "\" : [ \"" + string.Join("\" , \"", _lstValue) + "\" ]";
            _iParentCount += 1;
        }
    }
}
SolrResultTemp = SolrResultTemp + "}";

我不得不使用递归方法来完成工作。这是工作代码。

代码

    public IDictionary<string, object> ProcessJson(IDictionary<string, object> inputDic, LoansLogData loandata, string itemno, string parentKey = "", string childKey = "", int cnt = 1)
    {
        dynamic flexible = new ExpandoObject();

        IDictionary<string, object> ResultDic = (IDictionary<string, object>)flexible;
        try
        {

            foreach (KeyValuePair<string, object> entry in inputDic)
            {

                List<string> ElementCollection = new List<string>();
                List<string> _lstValue = new List<string>();
                if (entry.Value is System.Collections.ICollection)
                {
                    var countProp = entry.Value.GetType().GetProperty("Count");
                    var count = (int)countProp.GetValue(entry.Value, null);
                    int loopcount = 0;
                    foreach (var item in (System.Collections.ICollection)entry.Value)
                    {
                        if (item is Dictionary<string, object>)
                        {
                            if (entry.Key != null && entry.Key.Trim().StartsWith("@"))
