Remarks
You can use this delegate to represent a method that can be passed as a parameter without explicitly declaring a custom delegate. The encapsulated method must correspond to the method signature that is defined by this delegate. This means that the encapsulated method must have 12 parameters, each of which is passed to it by value, and that it must return a value.
Note
To reference a method that has 12 parameters and returns void (or in Visual Basic, that is declared as a Sub rather than as a Function), use the generic Action<T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12> delegate instead.
You can also use the Func<T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,TResult> delegate with anonymous methods and lambda expressions.
The underlying type of a lambda expression is one of the generic Func delegates. This makes it possible to pass a lambda expression as a parameter without explicitly assigning it to a delegate.
