Which is faster to execute delegate or interface?

Which is faster to execute delegate or interface?

Delegates are faster because they are only a pointer to a method. Interfaces need to use a v-table to then find a delegate; They are equal, but delegates are easier to use.

Is delegate same as interface?

Both delegates and interfaces enable a class designer to separate type declarations and implementation. A given interface can be inherited and implemented by any class or struct. A delegate can be created for a method on any class, as long as the method fits the method signature for the delegate.

Can we use delegate in interface?

A Delegate is a type which can’t be declared in an interface. You might want to either use an event(if appropriate) or declare a delegate outside the interface but in the same namespace.

Are delegates slow?

But having to get a delegate is slower than having to get an interface. Having to get a delegate over an interface method (or virtual method, not sure) is really slow (compare the 5 seconds of getting an object as an interface to the almost 4 minutes of doing the same to get the action).

When should I use delegates?

Delegates Overview

1. Delegates are similar to C++ function pointers, but are type safe.
2. Delegates allow methods to be passed as parameters.
3. Delegates can be used to define callback methods.
4. Delegates can be chained together; for example, multiple methods can be called on a single event.

When to use a delegate vs an interface?

If a delegate available in your scope you can use it. Interface is used when your class implements that interface, otherwise not. Delegates can me implemented any number of times. Interface can be implemented only one time.

Can a delegate be created for any method?

A delegate can be created for a method on any class, as long as the method fits the method signature for the delegate. An interface reference or a delegate can be used by an object that has no knowledge of the class that implements the interface or delegate method.

Can a delegate be inherited from a class?

Interface can be inherited and implemented by any class and a Delegate can be created for a method on any class, as long as the method suits the method signature of the delegate. An Interface or Delegate is being used by an object.

Why do we use single method interface in C #?

Because the ability to compare belongs to the class and the comparison algorithm does not change at run time, a single-method interface is ideal. Delegates and Interfaces are two distinct concepts in C# but they share a commonality. Both delegates and interfaces only include the declaration. Implementation is done by a different programming object.
