将泛型对象转换为类型化对象

public class Generic
{
public object AnonObject {get;set;}
public string ObjectType {get;set;}
}
public class TypedObject
{
public string Name {get;set;}
}
是否有办法使用ServiceStack serialization
或其他库将类[Generic]中的匿名属性AnonObject
转换为[TypedObject]。
。理想情况下,我正在寻找一个方法
TypedObject typed = generic.AnonObject.ConvertTo<TypedObject>();
或
TypedObject typed = generic.AnonObject As TypedOject;
您尝试过ServiceStack的内置自动映射方法吗?
TypedObject typed = generic.AnonObject.To<TypedObject>();
TypedObject typed = generic.AnonObject.TranslateTo<TypedObject>();
TypedObject typed = generic.AnonObject.ConvertTo<TypedObject>();
TypedObject typed = new TypedObject();
typed.PopulateWith(generic.AnonObject);
你仍然可以使用ServiceStack内置的自动映射在匿名对象和类型对象之间进行转换,但它们仍然必须具有相同的形状,例如:
public class Poco
{
public int Id { get; set; }
public string Name { get; set; }
}
var anon = new { Id = 1, Title = "Foo" };
var dto = anon.ConvertTo<Poco>();
dto.PrintDump();
打印填充的DTO:
{
Id: 1,
Title: Foo
}
ToObjectDictionary
和FromObjectDictionary
扩展方法在将松散类型数据结构转换为类型化POCO时也很有用,例如:
var dto = new User
{
FirstName = "First",
LastName = "Last",
Car = new Car { Age = 10, Name = "ZCar" },
};
Dictionary<string,object> map = dtoUser.ToObjectDictionary();
User user = (User)map.FromObjectDictionary(typeof(User));
如果以上选项不够,另一个可能的解决方案是将对象序列化/反序列化为JSON,例如:
var json = new { Id = 1, Title = "Foo" }.ToJson();
var dto = json.FromJson<Poco>();
