DirectCast requires the run-time type of an object variable
to bethe same
as the specified type.The run-time performance
ofDirectCast is better
than that of CType, if the specified type and the run-time
typeof the
expression are the same.
Ctype works fine if there is a valid conversion defined
between the
expression and the type.

The difference between the two keywords is that CType
succeeds as long as there is a valid conversion defined
between the expression and the type, whereas DirectCast
requires the run-time type of an object variable to be the
same as the specified type. If the specified type and the
run-time type of the expression are the same, however, the
run-time performance of DirectCast is better than that of
CType. DirectCast throws an InvalidCastException error if
the argument types do not match.
