【问题描述】:
我正在尝试将一个复杂对象添加到 Redis 中,但在从 Redis 检索值时,我将某些值设为空。下面是我正在尝试的粗略示例。我有一个复杂对象,我使用 JsonConvert 序列化该复杂对象并将其添加到 Redis 中。属性 CollectionID 有两个具有各自值的计数,但在从 Redis 获取它并反序列化后,该值将变为 null。
问题在于“客户”类是一个实体对象,而 json 序列化无法序列化该特定对象c#。这种情况有什么可能的解决方案吗?
class Program
{
private static IDatabase _cache;
private static ConnectionMultiplexer _connection;
static void Main(string[] args)
{
_connection = ConnectionMultiplexer.Connect("localhost");
_cache = _connection.GetDatabase();
List<Id> id = new List<Id>() { new Id() { ID = 10 }, new Id() { ID = 20 } };
Collection<Customers> collection = new Collection<Customers>() { new Customers(id) };
Product product = new Product(new Guid(), collection, 1);
_cache.StringSet("Redis_Key", GetSerializedString(product));
var value = JsonConvert.DeserializeObject<Product>(_cache.StringGet("Redis_Key"));
}
private static String GetSerializedString<Test1>(Test1 value)
{
return JsonConvert.SerializeObject(
value,
Formatting.Indented,
new JsonSerializerSettings
{
ReferenceLoopHandling = ReferenceLoopHandling.Serialize,
PreserveReferencesHandling = PreserveReferencesHandling.All
});
}
}
public class Product
{
public Product(
Guid parentGuid,
Collection<Customers> collection,
int number)
{
_parentGuid = parentGuid;
_collection = collection;
_number = number;
}
private Guid _parentGuid;
public Guid ParentGuid
{
get { return _parentGuid; }
}
private Collection<Customers> _collection;
public Collection<Customers> Collection
{
get { return _collection; }
}
private int _number;
public int number
{
get { return _number; }
}
}
public class Customers : Entity
{
.
.
.
public Customers(IEnumerable<Id> id)
{
_id = id;
}
private IEnumerable<Id> _id;
public IEnumerable<Id> CollectionID
{
get { return _id; }
}
.
.
.
}
public class Id
{
public int ID { get; set; }
}

您的问题stackoverflow.com/questions/60002178/… 的答案似乎尚未实现。你试过了吗?

我试过它适用于这种情况。但在这种情况下,“客户”类是一个实体类。我不确定 JsonConvert.SerializeObject 是否可以转换实体类。所以这个类客户没有被序列化。
