구문

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

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

returnValue = Observable.FromAsyncPattern(begin, _
    end)

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

public:
static Func<IObservable<Unit>^>^ FromAsyncPattern(
    Func<AsyncCallback^, Object^, IAsyncResult^>^ begin, 
    Action<IAsyncResult^>^ end
)

static member FromAsyncPattern : 
        begin:Func<AsyncCallback, Object, IAsyncResult> * 
        end:Action<IAsyncResult> -> Func<IObservable<Unit>> 

public static function FromAsyncPattern(
    begin : Func<AsyncCallback, Object, IAsyncResult>, 
    end : Action<IAsyncResult>
) : Func<IObservable<Unit>>

매개 변수

• begin
  형식: System.Func<AsyncCallback, Object, IAsyncResult>
  begin invoke 함수입니다.

• end
  형식: System.Action<IAsyncResult>
  end invoke 함수입니다.

반환 값

형식: System.Func<IObservable<Unit>>
Begin/End 호출 함수 쌍입니다.
