- d
- Delegate
The delegate that supplies the invocation list to remove from the invocation list of the current delegate.
Returns
A new delegate with an invocation list formed by taking the invocation list of the current delegate and removing the invocation list of d, if the invocation list of d is found within the current delegate's invocation list. Returns the current delegate if d is null or if the invocation list of d is not found within the current delegate's invocation list. Returns null if the invocation list of d is equal to the current delegate's invocation list.
Exceptions
The caller does not have access to the method represented by the delegate (for example, if the method is private).
Remarks
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.
