C#. Is it possible to create a method in which the return type will be determined in the method itself?

Question

.NET

Is it possible to create a method in which the return type will be determined in the method itself, or dotnet strict typing will not allow this?
The returned type will depend on what comes in the response from the API (several type options that will be explicitly specified in the method itself).

Answer 1

The returned type will depend on what comes in the response from the API (several type options that will be explicitly specified in the method itself).

Just make a class that has some kind of flag that tells the content type and N properties for each type.
If you have only two types - result and error, then use Either

Answer 2

You return the most basic type object, but this is shit code. The API usually returns a known data structure.

Answer 3

No, C# does not support type unioning. You can generalize, use a template or container, inherit, use an interface. But the most correct solution would be to rewrite the api method so that it returns a previously known type (this is the point of api).

Answer 4

You need generics " <T>"
