I want to have a class in which there is a variable. This variable can be of multiple types, depending on the instance. If in that instance it's initialised as an int, it's an int, if it's initialised as a string, it's a string.
This is what I currently have:

class bar
{
    public <???> foo;
}

CodePudding user response：

These problems can be solved using Generics, with Generics you're able to specify the type of your attributes when you're creating the object, for your problem this is a possible solution

public class Bar<T>
{
    public T foo;
}

And here is the Generics' documentation,https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/types/generics
