will help you Constructors in C# are explicitly not generics - you can't do what you want to do directly. Only member functions can have generic parameters.
However, that tells you what you can do: use a factory function instead of a constructor. Something like this:
public class PrinterFactory {

    public static ObjectPrinter CreatePrinter<T>(List<T> things) {
        return new ObjectPrinter<T>(things);
List<Fruit> myFruits = GetFruits();
var fruitPrinter = PrinterFactory.CreatePrinter(myFruits);

should help you out Your ToDataTable takes a List, and you're trying to pass it an object of type LeagueFixtures (which is what the deserialize method is returning). You could create a new list to pass into the ToDataTable with the myVar variable:
DataTable myDataTable = ToDataTable<LeagueFixtures>(new List<LeagueFixtures>{myVar});

Any of those help Maybe I misunderstand what you are after, but I don't see why you can't just do:
interface ISample {}
class Sample implements ISample {}

function toPlainObject<TInterface>(source: TInterface) : TInterface {
    return JSON.parse(JSON.stringify(source)) as TInterface;

let plain: ISample = toPlainObject(new Sample());
interface ISample {}
class Sample implements ISample {}

function toPlainObject<S extends D, D>(source: S) {
    return JSON.parse(JSON.stringify(source)) as D;

let plain: ISample = toPlainObject(new Sample());

Infer generic type argument from function callback

With these it helps Given a function foo, the type parameter T is properly inferred as string in this case: , I think this is what you are looking for
declare function foo<T>(callback: (bar: T) => void): void
foo((bar: string) => { })

declare function foo2<T>(callback: (bar: T) => void): void
foo2((a: { a: string }) => {} )

C# Generic method that can infer its type argument from expression parameter

wish of those help You can let it "infer" both generic arguments by writing explicitly the type of the lambda parameter:
service.DoWork((DateTime dt) => dt.Ticks);

Why is C# unable to infer the generic type argument type from a non-generic static method's signature?
