为什么servicestack不能将这个JSON反序列化为C#？

Question

我试图将以下JSON表示反序列化为强类型对象.我可以从c# - > json序列化它,但反之亦然.

C#

public class Package 
{
   public Guid Id {get;set;}
   public List<string> Email {get;set;}
   public List<Items> Items {get;set;}
}

public class Items
{
   public string Uri {get;set;}
   public int Width {get;set;}
   public int Height {get;set;}
}

JSON

{
    "Id":"84fd8751-6107-41af-9473-65aae51e042a",
    "Email":[
    "j@t.com"
    ],
    "Items":"[
       {"Uri":"http://localhost/foo.jpg","Width":234,"Height":313},
       {"Uri":"http://localhost/bar.jpg","Width":234,"Height":174}]"
}

用于反序列化的代码

var instance = JsonSerializer.DeserializeFromString<Package>(jsonData);

instance创建了对象,并且有2个项目对象,instance.Items但它们的所有属性都为null.

您在Items值周围有引号,因此将它们解析为字符串而不是数组/列表.删除它们赢得胜利.

"Items":[
       {"Uri":"http://localhost/foo.jpg","Width":234,"Height":313},
       {"Uri":"http://localhost/bar.jpg","Width":234,"Height":174}]
