Is there Scala equivalent of C# "as" keyword?

Question

Is there Scala equivalent of C# as keyword?

var something = obj as MyClass;

Scala's asInstanceOf throws java.lang.ClassCastException:

val something = obj.asInstanceOf[MyClass]

Answer 1

After reading up on C# a bit, I realized you probably meant this:

val foo = if (bar.isInstaceOf[Foo]) bar.asInstanceOf[Foo] else null.asInstanceOf[Foo]

It should be noted that using null is discouraged in Scala. You should really do this:

val foo = if (bar.isInstaceOf[Foo]) Some(bar.asInstanceOf[Foo]) else None
