How to check if a class implements an interface?
For example, I want to include an if that checks whether an object is of type IDisposable. How to do?
I tried something like:
MinhaClasse meuObjeto = new MinhaClasse();
if (typeof(meuObjeto) == IDisposable)
{
}
But it did not roll.
I found the answer in this SOEn query in the answer to Robert c barth
if (object is IBlah)or
IBlah myTest = originalObject as IBlah if (myTest != null)
With Reflection it is easy to identify whether the object of a class was implemented with interface IDisposable , inclusive, you can check if there are more implementations in this way
Class
public class Mecanismo: IDisposable
{
public void Dispose()
{
}
}
Code
Mecanismo mecanismo = new Mecanismo();
Type mectype = mecanismo.GetType();
var c = mectype.GetInterface("System.IDisposable"); //forma direta
if (c != null)
{
System.Console.WriteLine("Sim, foi implementado");
}
//ou
if (mectype.GetInterfaces().Where(x => x.Name.Equals("IDisposable")).Any())
{
System.Console.WriteLine("Sim, foi implementado");
}
