| re: C# interfaces
Hello,
there is also the 'as' keyword:
IMyInterface i = o as IMyInterface
if(i != null)
{
// i implements IMyInterface
}
else
{
// i does not implements IMyInterface
}
it allow you to bypass the cast that you need to put when using 'is' keyword
Now my question: Is there any fundamental diference between these 2 ways to
do slighty the same thing?
