Best way to call different APIs based on user input in C#?-CodePudding

I am developing one console application using C#. I need to call different-2 get APIs based on the input provided by the user and write the response on console.

So if user enters 1, I need to call a group weather api. If user enters 2 then I need to call temperature API. If user enters 3 then call some other API and if enters other then this just write invalid input.

For now I have just written multiple if and else if. Is there any better approach? Because this way there are multiple if else. And same goes for switch case as well.

I have also thought of creating mapping of input the endpoint like defining them in config file and then read into a dictionary.

So in future it can support below things.

if I need to call another API for input 4….. or No need to call any API for input 2. Or call different API on input 2.

well one way around this is to use Dictionary and Action :

private static readonly Dictionary<string, Action> MyApiCalls= new()
    {
        {
            "1", () =>
            {
                Console.WriteLine("im cool");
            }
        },

        {
            "2", () =>
            {
                Console.WriteLine("im really cool");
            }
        }
    };

and you use it like this :

 static void Main(string[] args)
    {
        var input = Console.ReadLine() ?? "1";

        MyApiCalls[input]();

        Console.ReadKey();
    }

so the action can be your api call or anything else.

if the number of cases is limited, I suggest to stick to a switch (cleaner then if-else in my opinion). A switch doesn't cost anything in speed.

Happy programming!
