類型參數

  • TSource
    來源的類型。
  • TResource
    資源的型別。

參數

  • resourceFactory
    類型：System.Func< TResource>
    取得資源物件的 Factory 函式。
  • observableFactory
    類型：System.Func< TResource、IObservable< TSource>>
    要取得相依于所取得資源的可觀察序列的 Factory 函式。

傳回值

類型：System.IObservable< TSource>
可觀察序列，其存留期控制相依資源物件的存留期。
