protected virtual Delegate RemoveImpl(
	Delegate d
)

Parameters

d
Type: System.Delegate
The delegate that supplies the invocation list to remove from the invocation list of the current delegate.

Return Value

Type: System.Delegate
A new delegate with an invocation list formed by taking the invocation list of the current delegate and removing the invocation list of value, if the invocation list of value is found within the current delegate's invocation list. Returns the current delegate if value is null or if the invocation list of value is not found within the current delegate's invocation list. Returns null if the invocation list of value is equal to the current delegate's invocation list.

ExceptionCondition
MemberAccessException

The caller does not have access to the method represented by the delegate (for example, if the method is private).

MethodAccessException

Application code attempts to access this member late-bound, for example, by using the Type.InvokeMember method.

If the invocation list of value matches a contiguous set of elements in the current delegate's invocation list, then the invocation list of value is said to occur within the current delegate's invocation list. If the invocation list of value occurs more than once in the current delegate's invocation list, the last occurrence is removed.
