复杂的JSON字符串转换为对象的问题。

[siaosa]

怎样将下列JSON字符串转换为一个对象呀？ 特别是linkArray里的内容，是多列的，而且长度不一。

{
  "class_": "Model",
  "name": "aaaaa",
  "linkArray": [
    {
      "from": 1,
      "fromPort": "A",
      "toPort": "T"
    },
    {
      "from": 2,
      "fromPort": "B",
      "toPort": "T"
    },
    {
      "from": 3,
      "toPort": "T",
      "to": 6
    },
    {
      "from": 4,
      "toPort": "T",
      "desc": "obj"
    },
    {
      "from": 4,
      "fromPort": "A",
      "toPort": "T",
      "desc": "obj"
    },
    {
      "from": 5,
      "fromPort": "B",
      "toPort": "T"
    }
  ]
}

vs菜单 ，编辑=》选择性粘贴=》Json粘贴

public class Rootobject
    {
        public string class_ { get; set; }
        public string name { get; set; }
        public Linkarray[] linkArray { get; set; }
    }

    public class Linkarray
    {
        public int from { get; set; }
        public string fromPort { get; set; }
        public string toPort { get; set; }
        public int to { get; set; }
        public string desc { get; set; }
    }

创建对应的类，包含所有字段，反系列化时自动生成默认值，系列化时增加选项，忽略空值

首先将json对象转为json字符串，再使用Newtonsoft.Json

  var jsonStr="{\"class_\": \"Model\",\"name\": \"aaaaa\",\"linkArray\": [{\"from\": 1,\"fromPort\": \"A\",\"toPort\": \"T\"},{\"from\": 2,\"fromPort\": \"B\",\"toPort\": \"T\"},{\"from\": 3,\"toPort\": \"T\",\"to\": 6},{\"from\": 4, \"toPort\": \"T\",\"desc\": \"obj\"},{\"from\": 4,\"fromPort\": \"A\",\"toPort\": \"T\",\"desc\": \"obj\"},{ \"from\": 5,\"fromPort\": \"B\",\"toPort\": \"T\"}]}";
             JsonSerializerSettings setting = new JsonSerializerSettings();
            setting.NullValueHandling = NullValueHandling.Ignore;
            var model= JsonConvert.DeserializeObject<Demo>(jsonStr, setting);

下面是Demo类

 public class Demo
    {
       public string class_ { get; set; }
       public string name { get; set; }
       public List<LinkArray> linkArray { get; set; }
    }
   public class LinkArray
   {
       public int from { get; set; }
       public string fromPort { get; set; }
       public string toPort { get; set; }
       public string desc { get; set; }
       public string to { get; set; }
   }
