Sintaxe

'Declaration
Public Shared Function FromAsyncPattern(Of TResult) ( _
    begin As Func(Of AsyncCallback, Object, IAsyncResult), _
    end As Func(Of IAsyncResult, TResult) _
) As Func(Of IObservable(Of TResult))

'Usage
Dim begin As Func(Of AsyncCallback, Object, IAsyncResult)
Dim end As Func(Of IAsyncResult, TResult)
Dim returnValue As Func(Of IObservable(Of TResult))

returnValue = Observable.FromAsyncPattern(begin, _
    end)

public static Func<IObservable<TResult>> FromAsyncPattern<TResult>(
    Func<AsyncCallback, Object, IAsyncResult> begin,
    Func<IAsyncResult, TResult> end
)

public:
generic<typename TResult>
static Func<IObservable<TResult>^>^ FromAsyncPattern(
    Func<AsyncCallback^, Object^, IAsyncResult^>^ begin, 
    Func<IAsyncResult^, TResult>^ end
)

static member FromAsyncPattern :
