1: Unicast delegation (synchronous call)
operation result:
2: Multicast delegation (synchronous call)

3: Direct synchronous call
Operation result:
4: Indirect synchronous call (unicast):
Multicast mode:
action1 += action2;
action2 += action3;
action1.Invoke();
The running result is the same as the direct synchronous call
5: Delegate implicit asynchronous call
Operation result:
6: Delegate display asynchronous call
