ActivityFunc<T1, T2, T3, TResult> Class
Defines an activity delegate with three in arguments of type T and one out argument of type TResult.
Assembly: System.Activities (in System.Activities.dll)
System.Activities::ActivityDelegate

generic<typename T1, typename T2, typename T3, typename TResult> public ref class ActivityFunc sealed : ActivityDelegate
Type Parameters
- T1
The type of the first in argument of the activity delegate.
- T2
The type of the second in argument of the activity delegate.
- T3
The type of the third in argument of the activity delegate.
- TResult
The type of the out argument of the activity delegate.
| Name | Description | |
|---|---|---|
![]() | ActivityFunc<T1, T2, T3, TResult>() | Creates a new instance of the ActivityFunc<T1, T2, T3, TResult> class. |
| Name | Description | |
|---|---|---|
![]() | Argument1 | Gets or sets the first in argument of the activity delegate. |
![]() | Argument2 | Gets or sets the second in argument of the activity delegate. |
![]() | Argument3 | Gets or sets the third in argument of the activity delegate. |
![]() | DisplayName | Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking.(Inherited from ActivityDelegate.) |
![]() | Handler | Gets or sets the activity that is represented by this ActivityDelegate.(Inherited from ActivityDelegate.) |
![]() | Result | Gets or sets the out argument of the activity delegate. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object^) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetResultArgument() | When implemented in a derived class, returns the DelegateOutArgument of the ActivityDelegate.(Inherited from ActivityDelegate.) |
![]() | GetType() | |
![]() | ShouldSerializeDisplayName() | Indicates whether the DisplayName property value should be serialized to XAML.(Inherited from ActivityDelegate.) |
![]() | ToString() | Returns a String representation of the ActivityDelegate that contains the DisplayName.(Inherited from ActivityDelegate.) |
The ActivityDelegate enables activity authors to expose callbacks with specific signatures that users of the activity can provide activity-based handlers for. ActivityFunc<T1, T2, T3, TResult> is an ActivityDelegate that returns a value. The signature of the ActivityFunc<T1, T2, T3, TResult> is specified as generic type arguments.
There are multiple generic versions of this type that take from 1 to 16 in arguments, plus the out argument, for the activity that is called. There are also ActivityAction types for activity delegates that do not return values.
