Observable.FromAsyncPattern<TResult> メソッド (Func<AsyncCallback, Object, IAsyncResult>, Func<IAsyncResult, TResult>)

Begin/End 呼び出し関数ペアを非同期関数に変換します。

Namespace:System.Reactive.Linq
アセンブリ： System.Reactive (System.Reactive.dll)

構文

'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 : 
        begin:Func<AsyncCallback, Object, IAsyncResult> * 
        end:Func<IAsyncResult, 'TResult> -> Func<IObservable<'TResult>> 

JScript does not support generic types and methods.
