Action<T1,T2,T3,T4,T5,T6> Delegate

Definition

Namespace:

System

Assembly:

System.Runtime.dll

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

generic <typename T1, typename T2, typename T3, typename T4, typename T5, typename T6>
public delegate void Action(T1 arg1, T2 arg2, T3 arg3, T4 arg4, T5 arg5, T6 arg6);

public delegate void Action<in T1,in T2,in T3,in T4,in T5,in T6>(T1 arg1, T2 arg2, T3 arg3, T4 arg4, T5 arg5, T6 arg6);

type Action<'T1, 'T2, 'T3, 'T4, 'T5, 'T6> = delegate of 'T1 * 'T2 * 'T3 * 'T4 * 'T5 * 'T6 -> unit

Public Delegate Sub Action(Of In T1, In T2, In T3, In T4, In T5, In T6)(arg1 As T1, arg2 As T2, arg3 As T3, arg4 As T4, arg5 As T5, arg6 As T6)

Type Parameters

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.

T2

The type of the second 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.

T3

The type of the third 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.

T4

The type of the fourth 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.

T5

The type of the fifth 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.

T6

The type of the sixth 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.

Parameters

arg1

T1

The first parameter of the method that this delegate encapsulates.

arg2

T2

The second parameter of the method that this delegate encapsulates.

arg3

T3

The third parameter of the method that this delegate encapsulates.

arg4

T4

The fourth parameter of the method that this delegate encapsulates.

arg5

T5

The fifth parameter of the method that this delegate encapsulates.

arg6

T6

The sixth parameter of the method that this delegate encapsulates.

Remarks

You can use the Action<T1,T2,T3,T4,T5,T6> 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 six 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.

Note

To reference a method that has six parameters and returns a value, use the generic Func<T1,T2,T3,T4,T5,T6,TResult> delegate instead.

You can also use the Action<T1,T2,T3,T4,T5,T6> delegate with anonymous methods and lambda expressions.

Extension Methods

GetMethodInfo(Delegate)

Gets an object that represents the method represented by the specified delegate.
