Returns
A new delegate with an invocation list formed by taking the invocation list of source

, if the invocation list of value
is found within the invocation list of source
. Returns source

is not found within the invocation list of source
. Returns a null reference if the invocation list of value
is equal to the invocation list of source
or if source
is a null reference.
Exceptions

occurs more than once in the invocation list of source
, the last occurrence is removed.
