C# call interface method within class

Question

interface ILol
{
   void LOL();
}

class Rofl : ILol
{
   void ILol.LOL()
   {
      GlobalLOLHandler.RaiseROFLCOPTER(this);
   }
   public Rofl()
   {
      //Is there shorter way of writing this or i is there "other" problem with implementation??
      (this as ILol).LOL();
   }
}

Answer 1

Don't use as, just cast:

((ILol)this).LOL();

Answer 2

You may want to change the cast from (this as ILol) to ((ILol)this). An as cast is allowed to return null, which could cause confusing errors later and which the compiler has to test for.

Answer 3

No not if you are explicitly implementing the interface. If you make it implicit by removing the interface name from the implemented method it'll work as you want.

void LOL()
{
    GlobalLOLHandler.RaiseROFLCOPTER(this);
}
public Rofl()
{
    LOL();
}

Answer 4

You've implemented the interface explicitly which, in general, you don't need to do. Instead, just implement it implicitly and call it as you would any other method:

class Rofl : ILol
{
    public void LOL() { ... }

    public Rofl()
    {
        LOL();
    }
}

(Note your implementation will also need to be public.)

Answer 5

You don't need to cast at all. Since ROFL implements ILOL you can simply call this.LOL() or even just LOL();
