Observable

Observable.ToAsync<TResult> Method (Func<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 TResult) ( _
    function As Func(Of TResult) _
) As Func(Of IObservable(Of TResult))
'Usage
Dim function As Func(Of TResult)
Dim returnValue As Func(Of IObservable(Of TResult))

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

Type Parameters

  • TResult
    The type of result.

Parameters

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

Return Value

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