【问题描述】：

我对 JSON 格式的反序列化服务器响应有疑问。我使用 JavaScriptSerializer，但我得到了 null。

{"0":{"Name":"BusinessSegmentFilter","Items":{"0":{"ItemName":"1650","IsEditable":false,"IsClicked":false,"IsSelected" :false},"1":{"ItemName":"1457","IsEditable":false,"IsClicked":false,"IsSelected":false},"2":{"ItemName":"1649"," IsEditable":false,"IsClicked":false,"IsSelected":false},"3":{"ItemName":"1651","IsEditable":false,"IsClicked":false,"IsSelected":false}, "4":{"ItemName":"4480","IsEditable":false,"IsClicked":false,"IsSelected":false},"5":{"ItemName":"1692","IsEditable":false ,"IsClicked":false,"IsSelected":false},"6":{"ItemName":"4012","IsEditable":false,"IsClicked":false,"IsSelected":false},"7": {"ItemName":"4198","IsEditable":false,"IsClicked":false,"IsSelected":false},"8":{"ItemName":"1652","IsEditable":false,"IsClicked" :false,"IsSelected":false}},"MaxValue":null,"MinValue":null},"1":{"Name":"BusinessSegmentFilter","Items":{"0":{"ItemName" :"1650","IsEditable":false,"IsClicked":false,"IsSelected":false},"1":{"ItemName":"1457","IsEditable":false,"IsClicked":false,"被选中” :false},"2":{"ItemName":"1649","IsEditable":false,"IsClicked":false,"IsSelected":false},"3":{"ItemName":"1651"," IsEditable":false,"IsClicked":false,"IsSelected":false},"4":{"ItemName":"4480","IsEditable":false,"IsClicked":false,"IsSelected":false}, "5":{"ItemName":"1692","IsEditable":false,"IsClicked":false,"IsSelected":false},"6":{"ItemName":"4012","IsEditable":false ,"IsClicked":false,"IsSelected":false},"7":{"ItemName":"4198","IsEditable":false,"IsClicked":false,"IsSelected":false},"8": {"ItemName":"1652","IsEditable":false,"IsClicked":false,"IsSelected":false}},"MaxValue":null,"MinValue":null}}

 var resposne = serializer.Deserialize<AjaxResposne>(eventArgument);


  public class AjaxResposne
    {

    public string Name { get; set;  }
    public List<Item> Items { get; set; }
    public string MaxValue { get; set; }
    public string MinValue { get; set;  }
}

public class  Item
{
    public string ItemName { get; set;  }
    public bool IsEditable { get; set;  }
    public bool IsClicked { get; set;  }
    public bool IsSelected { get; set;  }


}

【解决方案1】：

您的 json 包含属性名称，如 "0"、"1" 等，因此您必须使用一些技巧来正确反序列化 (Dictionary<string,SomeClass>)。

var obj = new JavaScriptSerializer()
              .Deserialize<Dictionary<string,ItemCollection>>(json);

public class ItemCollection
{
    public string Name { get; set; }
    public string  MaxVlaue { get; set; }
    public string MinValue { get; set; }
    public Dictionary<string, Item> Items  { get; set; }
}

public class Item
{
    public string ItemName { get; set; }
    public bool IsEditable { get; set; }
    public bool IsClicked { get; set; }
    public bool IsSelected { get; set; }
}

【解决方案2】：

您的 JSON 错误，与语法无关，而是与 JavaScriptSerializer 期望您的列表的结构方式有关。

删除索引并使用常规数组，一切都按预期工作：

{
    "Name": "BusinessSegmentFilter",
    "Items": [
        {
            "ItemName": "1650",
            "IsEditable": false,
            "IsClicked": false,
            "IsSelected": false
        }
    ],
    "MaxValue": null,
    "MinValue": null
}
