Converts the function into an asynchronous function.

Namespace:  System.Reactive.Linq
Assembly:  System.Reactive (in System.Reactive.dll)

Syntax

'Declaration

Public Shared Function ToAsync(Of T1, T2, T3, T4, TResult) ( _
    function As Func(Of T1, T2, T3, T4, TResult) _
) As Func(Of T1, T2, T3, T4, IObservable(Of TResult))
'Usage
Dim function As Func(Of T1, T2, T3, T4, TResult)
Dim returnValue As Func(Of T1, T2, T3, T4, IObservable(Of TResult))

returnValue = function.ToAsync()

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.
  • T4
    The fourth type of function.
  • TResult
    The type of result.

Parameters

  • function
    Type: System.Func<T1, T2, T3, T4, TResult>
    The function used to synchronization.

Return Value

Type: System.Func<T1, T2, T3, T4, IObservable<TResult>>
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 Func<T1, T2, T3, T4, TResult>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
