Delegate instantiation

An instance of a delegate is created by a delegate-creation-expression (14.5.10.3). The newly created delegate instance then refers to either: The static method referenced in the delegate-creation-expression, or The target object (which cannot be null) and instance method referenced in the delegate-creation-expression, or Another delegate [Example: For example: delegate void D(int x); class Test { public static void M1(int i) {...} public void M2(int i) {...} } class Demo { static void Main() { D cd1 = new D(Test.M1); // static method Test t = new Test(); D cd2 = new D(t.M2); // instance method D cd3 = new D(cd2); // another delegate } } end example]
Once instantiated, delegate instances always refer to the same target object and method.

[Note: Remember, when two delegates are combined, or one is removed from another, a new delegate results with its own invocation list; the invocation lists of the delegates combined or removed remain unchanged. end note]
