Action(T1, T2, T3, T4, T5) Delegate

Encapsulates a method that has five parameters and does not return a value.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

type Action = 
    delegate of  
        arg1:'T1 * 
        arg2:'T2 * 
        arg3:'T3 * 
        arg4:'T4 * 
        arg5:'T5 -> unit

Type Parameters

in T1

The type of the first parameter of the method that this delegate encapsulates.

This type parameter is contravariant. That is, you can use either the type you specified or any type that is less derived. For more information about covariance and contravariance, see Covariance and Contravariance in Generics.

in T2

The type of the second parameter of the method that this delegate encapsulates.

in T3

The type of the third parameter of the method that this delegate encapsulates.

in T4

The type of the fourth parameter of the method that this delegate encapsulates.

in T5

The type of the fifth parameter of the method that this delegate encapsulates.

Parameters

arg1
Type: T1

The first parameter of the method that this delegate encapsulates.

arg2
Type: T2

The second parameter of the method that this delegate encapsulates.

arg3
Type: T3

The third parameter of the method that this delegate encapsulates.

arg4
Type: T4

The fourth parameter of the method that this delegate encapsulates.

arg5
Type: T5

The fifth parameter of the method that this delegate encapsulates.

You can use the Action(T1, T2, T3, T4, T5) 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 five 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 SubEnd 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.

NoteNote

To reference a method that has five parameters and returns a value, use the generic Func(T1, T2, T3, T4, T5, TResult) delegate instead.

You can also use the Action(T1, T2, T3, T4, T5) delegate with anonymous methods and lambda expressions.
