Observable

Observable.ToAsync<T, TResult> Method (Func<T, TResult>)

Converts the function into an asynchronous function.

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

Syntax

'Declaration
<ExtensionAttribute> _
Public Shared Function ToAsync(Of T, TResult) ( _
    function As Func(Of T, TResult) _
) As Func(Of T, IObservable(Of TResult))
'Usage
Dim function As Func(Of T, TResult)
Dim returnValue As Func(Of T, IObservable(Of TResult))

returnValue = function.ToAsync()
public static Func<T, IObservable<TResult>> ToAsync<T, TResult>(
    this Func<T, TResult> function
)
[ExtensionAttribute]
public:
generic<typename T, typename TResult>
static Func<T, IObservable<TResult>^>^ ToAsync(
    Func<T, TResult>^ function
)
static member ToAsync : 
        function:Func<'T, 'TResult> -> Func<'T, IObservable<'TResult>> 
JScript does not support generic types and methods.

Type Parameters

  • T
    The type.

  • TResult
    The type of result.

Parameters

  • function
    Type: System.Func<T, TResult>
    The function used to synchronization.

Return Value

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