英文:
Serializing ReadItemAsync() response based on a property of the document
问题
我需要根据存储在Azure Cosmos DB中的文档属性对ReadItemAsync()的响应进行序列化。
所以如果document.type = "dog"，我需要序列化为ReadItemAsync<Dog>()，依此类推。
在检索之前，我不知道类型是什么。
有什么好的解决方案吗？
英文:
I need to serialize the response from ReadItemAsync() based on a property of the document stored in Azure Cosmos DB.
So if document.type = "dog", I need to serialize as ReadItemAsync<Dog>() and so on.
I don't know the type before retrieving it.
What's a good solution for this?

你可以将其反序列化为 JObject 并在将其映射到特定类之前读取类型属性。
var response = await container.ReadItemAsync<JObject>("myId", new("myPk"));
if (response.Resource.Value<string>("type") == "dog")
{
var dog = response.Resource.ToObject<Dog>();
}
英文:
You could deserialize it to a JObject and read the type property before mapping it to a specific class.
var response = await container.ReadItemAsync<JObject>("myId", new("myPk"));
if (response.Resource.Value<string>("type") == "dog")
{
var dog = response.Resource.ToObject<Dog>();
}
