模式在不同的命名空间中调用相同的对象

Question

I'm creating a web forms project in c#.

One of the key requirements is to post out to an API, however there's not one but several API's available.

At present the HttpClient object is uniquely defined for each API in a different namespace, like below:

MyCo.Myapp.PostApi.Client1.ClientObject
MyCo.Myapp.PostApi.Client2.ClientObject

Aside from the HttpClient , the endpoint url and mediatypes are stored as well as a few other configuration objects.

The idea being that the namespace Client1 or Client2 is stored in a database, and can be used to retrieve the location of the correct API, to create the object.

None of the above is set in stone - it's in concept form - so I wondered if there are any other alternatives to this solution which I can consider.

Any advice appreciated.

This seems like a potential candidate for an Abstract Factory approach. What you're describing sounds familiar to how one would connect to various database types using System.Data.Common

var settings = GetInfoFromDatabase();
var factory = ClientObjectFactory.Create(settings);

var clientObject = factory.CreateClientObject();
clientObject.Post("");  // This could be any of the client objects.  

However since you don't have control over client APIs you could have the underlying factory perform the post:

factory.Post(clientObject, data);
