類型參數
- TSource
來源的類型。
- TBufferOpening
可觀察序列的類型,其元素代表每個產生的緩衝區的開頭。
- TBufferClosing
可觀察序列的類型,其元素表示每個產生的緩衝區的結尾。
參數
- source
類型:System.IObservable< TSource>
要產生緩衝區的來源序列。
- bufferOpenings
類型:System.IObservable< TBufferOpening>
可觀察的序列,其元素表示新緩衝區的建立。
- bufferClosingSelector
類型:System.Func< TBufferOpening、IObservable< TBufferClosing>>
叫用以定義每個產生的緩衝區結尾的函式。
傳回值
類型:System.IObservable<IList< TSource>>
可觀察的緩衝區序列。
使用注意事項
在 Visual Basic 和 C# 中,您可以在IObservable< TSource > 類型的任何物件上呼叫此方法作為實例方法。 使用執行個體方法語法呼叫這個方法時,請省略第一個參數。 如需詳細資訊,請參閱 或 。
