c# - 反序列化字符串不转换数组

Question

我试图将这个字符串反序列化为一个对象，但每次转换时，角色属性都不会转换回来。

{"LoginAttemptId":235,"UserProfileId":4,"Username":"devclient1","Id":null,"SubscriptionType":null,"Roles":["Client"]}

我已经尝试了这两种反序列化方法:

PauperToPresidentSerializedModel serializeModel = 
               JsonConvert.DeserializeObject<PauperToPresidentSerializedModel>(decUserData);

                //PauperToPresidentSerializedModel serializeModel
                //    = serializer.Deserialize<PauperToPresidentSerializedModel>(decUserData);

并且都给我和反对 Roles 属性为 Null 的地方，而不是在其中包含“Client”。

这是 PauperToPresidentSerializedModel 对象定义

public class PauperToPresidentSerializedModel
    {
        public long LoginAttemptId { get; set; }

        public long UserProfileId { get; set; }
        public string Username { get; set; }

        public string Id { get; set; }

        public string SubscriptionType { get; set; }
        public string[] Roles { get; private set; }
        public PauperToPresidentSerializedModel(PauperToPresidentPrincipal principal)
        {
            LoginAttemptId = principal.LoginAttemptId;
            UserProfileId = principal.UserProfileId;
            Username = principal.Username;
            Id = principal.Id;
            SubscriptionType = principal.SubscriptionType;
            Roles = principal.Roles;
        }
        public PauperToPresidentSerializedModel()
        {            
        }
    }

Answer 1

您的 Roles 字段有一个 private setter。你可以:

1. 公开

2. 让契约(Contract)解析器访问私有(private)字段:

   contractResolver.DefaultMembersSearchFlags |= BindingFlags.NonPublic;

3. 创建自定义契约(Contract)解析器(我猜您不想走那条路)。
