如何遍歷json字符串（json對象的json數組）並使用c＃動態添加屬性？

-3

您好我需要一種方法來遍歷給定的json數組的json對象，並根據每個json對象的「F」屬性中的反斜槓數量（/）動態地爲每個json對象添加名爲「depth」的屬性我需要爲我的項目。如何遍歷json字符串（json對象的json數組）並使用c＃動態添加屬性？

這裏是JSON字符串：

[ 
    { 
     "A":"0", 
     "B":"0", 
     "ID":"000001", 
     "C":"Class", 
     "D":"/000001", 

     "F":"/Class", 
     "children":[ 
     { 
      "A":"1", 
      "B":"1", 
      "ID":"000004", 
      "C":"Test1", 
      "D":"/000001/000004", 

      "F":"/Class/Test1" 
     }, 
     { 
      "A":"0",

例如，如果你看一下第一個JSON對象「F」屬性包含1回斜線因此「深度「屬性值應該是1.

_「這是代碼」_ - 您沒有發佈任何代碼。只是JSON數據。顯而易見的方法是將源數據反序列化爲實際的對象模型，然後使用新的'depth'屬性將數據作爲JSON進行研究。根據您使用的處理JSON的方式，您可以反序列化爲具有'depth'屬性的對象（該對象將保持未初始化狀態），設置屬性然後重新序列化，或者僅從一個數據中複製沒有財產的結構給另一個擁有財產的財產，在這個財產中你將它設定爲你想要的價值。 –

我假設您只需要在響應中添加另一個property(F)，我寧願在C#代碼中添加新屬性比改變Json。一旦你映射Json響應與響應類對象(C#)，使用Foreach循環通過每個children對象檢查你想要的條件和add F。

試試這個。

的foreach（在root.children變種X）{//條件}

您可以使用Newtonsoft.Json包和JPath（http://goessner.net/articles/JsonPath/）

，這樣你的代碼可以是這樣的：

var parsedJson = JToken.Parse(json); 
var nodes = parsedJson.SelectTokens("$..*"); 
foreach (var node in nodes.OfType<JObject>()) 
{ 
    var pathValue = node.Property("F")?.Value?.Value<string>(); 
    if (string.IsNullOrWhiteSpace(pathValue)) 
    { 
     continue; 
    } 

    var depth = pathValue.Split(new[] { '/' }, StringSplitOptions.None).Length; 
    node.Add("depth", depth - 1); 
} 
var modifiedJson = parsedJson.ToString();
