Public Shared Function ToAsync(Of T1, T2, T3) ( _
    action As Action(Of T1, T2, T3) _
) As Func(Of T1, T2, T3, IObservable(Of Unit))
'Usage
Dim action As Action(Of T1, T2, T3)
Dim returnValue As Func(Of T1, T2, T3, IObservable(Of Unit))

returnValue = action.ToAsync()

[ExtensionAttribute]

JScript does not support generic types and methods.

Type Parameters

  • T1
    The first type of function.
  • T2
    The second type of function.
  • T3
    The third type of function.

Parameters

  • action
    Type: System.Action<T1, T2, T3>
    The action used to synchronization.

Return Value

Type: System.Func<T1, T2, T3, IObservable<Unit>>
The function into an asynchronous function.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Action<T1, T2, T3>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
