Question

Given the following generic interface and implementing class:

public interface IRepository<T> {     // U has to be of type T of a subtype of T     IQueryable<U> Find<U>() where U : T; }  public class PersonRepository : IRepository<Employee> {  } 

How could I call the Find method without specififying U?

var repository = new EmployeeRepository(); // Can't be done IQueryable<Employee> people = repository.Find();  // Has to be, but isn't Employee a given in this context? IQueryable<Employee> people = repository.Find<Employee>();  // Here I'm being specific IQueryable<Manager> managers = repository.Find<Manager>(); 

In other words, what can be done to get type inference?

Thanks!

Answer 1

How about writing

var people = repository.Find<Employee>(); 

It’s saving the same amount of typing but in a different way.
