如何遍历json字符串（json对象的json数组）并使用c＃动态添加属性？

-3

您好我需要一种方法来遍历给定的json数组的json对象，并根据每个json对象的“F”属性中的反斜杠数量（/）动态地为每个json对象添加名为“depth”的属性我需要为我的项目。如何遍历json字符串（json对象的json数组）并使用c＃动态添加属性？

这里是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", 
      "B":"0",

      ] 
     } 
     ] 
    } 
]

例如，如果你看一下第一个JSON对象 “F” 属性包含1回斜线因此“深度“属性值应该是1.

_“这是代码”_ - 您没有发布任何代码。只是JSON数据。显而易见的方法是将源数据反序列化为实际的对象模型，然后使用新的'depth'属性将数据作为JSON进行研究。根据您使用的处理JSON的方式，您可以反序列化为具有'depth'属性的对象（该对象将保持未初始化状态），设置属性然后重新序列化，或者仅从一个数据中复制没有财产的结构给另一个拥有财产的财产，在这个财产中你将它设定为你想要的价值。 –

我假设您只需要在响应中添加另一个property(F)，我宁愿在C#代码中添加新属性比改变Json。一旦你映射Json响应与响应类对象(C#)，使用Foreach循环通过每个children对象检查你想要的条件和add F。

试试这个。

的foreach（在root.children变种X）{//条件}

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

，这样你的代码可以是这样的：

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();
