You can use the Action<T1, T2, T3, T4, T5, T6, T7, T8, T9> delegate to pass a method 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 nine parameters that are all passed to it by value, and it must not return a value. (In C#, the method must return void. In Visual Basic, it must be defined by the Sub…End Sub construct. It can also be a method that returns a value that is ignored.) Typically, such a method is used to perform an operation.
To reference a method that has nine parameters and returns a value, use the generic Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, TResult> delegate instead. |
You can also use the Action<T1, T2, T3, T4, T5, T6, T7, T8, T9> delegate with anonymous methods and lambda expressions.
