Important Points:

  • Delegates are types that can reference methods of a certain kind of signature;
  • Delegates allow us to pass methods as arguments;
  • The syntax of a creating a new delegate type is as follows: delegate <return type> <type name> (parameter1, parameter2, …);;
  • We can create a variable using a delegate type and assign it a method reference using the following syntax: DelegateTypeName variableName = methodName;;
  • More methods can be added to a delegate instance using the += operator;
  • Methods can be removed from a delegate instance using the -+ operator;
  • In case there are multiple methods in a delegate instance that return a value, the value of the last executed method is returned;
