bool
HasSingleTarget
Gets a value that indicates whether the <see cref="T:System.Delegate" /> has a single invocation target.
public
MethodInfo
Method
Gets the method represented by the delegate.
public
object
Target

Methods
protected
delegate
CombineImpl(delegate follow)
Inherited from MulticastDelegate
follow
The delegate to combine with this delegate.
Returns A delegate that is the new root of the <see cref="T:System.MulticastDelegate" /> invocation list.
Combines this <see cref="T:System.Delegate" /> with the specified <see cref="T:System.Delegate" /> to form a new delegate.
public
bool
Equals(object obj)
Inherited from MulticastDelegate
obj
The object to compare with this instance.
Returns <see langword="true" /> if <paramref name="obj" /> and this instance have the same invocation lists; otherwise, <see langword="false" /> .
Determines whether this multicast delegate and the specified object are equal.
public
int
GetHashCode()
Inherited from MulticastDelegate
Returns A 32-bit signed integer hash code.
Returns the hash code for this instance.
public
delegate[]
GetInvocationList()
Inherited from MulticastDelegate
Returns An array of delegates whose invocation lists collectively match the invocation list of this instance.
Returns the invocation list of this multicast delegate, in invocation order.
protected
MethodInfo
GetMethodImpl()
Inherited from MulticastDelegate

protected
delegate
RemoveImpl(delegate value)
Inherited from MulticastDelegate
value
The delegate to search for in the invocation list.
Returns If <paramref name="value" /> is found in the invocation list for this instance, then a new <see cref="T:System.Delegate" /> without <paramref name="value" /> in its invocation list; otherwise, this instance with its original invocation list.
Removes an element from the invocation list of this <see cref="T:System.MulticastDelegate" /> that is equal to the specified delegate.
