如何将json转换为C中的扁平结构＃

Question

我正在尝试在C＃中编写将JSON转换为键/值对的函数。它应该支持数组。因此，例如以下JSON：

{ 
    title: title_value, 
    components: [ 
     { 
      component_id: id1, 
      menu: [ 
        {title: menu_title1}, 
        {title: menu_title_x}, 
        {id: menu_id1}  
      ] 
     }, 
     { 
      component_id: id2, 
      menu: [ 
        {title: menu_title2}, 
        {id: menu_id2}  
      ] 
     } 
    ] 
} 

应转换为：

• 标题= title_value
• components.0.component_id = ID1
• components.0.menu.0.title = menu_title1
• components.0.menu.1.title = menu_title_x
• components.0.menu.2.id = menu_id1
• components.1.component_id = ID2
• components.1.menu.0.title = menu_title2
• components.1.menu.1.id = menu_id2

这是任何简单的方法这个任务？当我开始考虑数组和嵌套数组时，逻辑变得很复杂。

解决方法如下。 JavaScriptSerializer从json字符串（'json'）创建对象（'o'），而不是通过BuildVariablesList方法遍历对象并填充包含结果的字典（'additionalParameters'）。

var jss = new JavaScriptSerializer(); 
    var o = return new DynamicJsonObject(jss.Deserialize<Dictionary<string, object>>(json)); 

    var additionalParameters = new Dictionary<string, string>(); 
    BuildVariablesList(o.GetInternalDictionary(), "", additionalParameters); 

    private static string AppendToPathString (string path, object part) 
    { 
     return path.Trim().Length == 0 ? part.ToString() : path + '.' + part; 
    } 

    public static void BuildVariablesList(object obj, string path, Dictionary<string, string> result) 
    { 
     if (obj is ArrayList) 
     { 
      var arrayObj = obj as ArrayList; 
      for (var i = 0; i<arrayObj.Count; i++) 
      { 
       BuildVariablesList(arrayObj[i], AppendToPathString(path,i), result); 
      } 
     }else if (obj is Dictionary<string, object>) 
     { 
      var dictObject = obj as Dictionary<string, object>; 
      foreach (var entry in dictObject) 
      { 
       if (entry.Value is String && (path.Trim().Length > 0 || !ReservedFieldNames.Contains(entry.Key.ToLower()))) 
       { 
        result.Add(AppendToPathString(path,entry.Key), entry.Value as String); 
       } 
       else if (entry.Value is Dictionary<string, object>) 
       { 
        BuildVariablesList(entry.Value as Dictionary<string, object>, AppendToPathString(path, entry.Key), result); 
       } 
       else if (entry.Value is ArrayList) 
       { 
        BuildVariablesList(entry.Value as ArrayList, AppendToPathString(path, entry.Key), result); 
       } 
      } 
     }    
    }
