Observable.Merge(Of TSource) Method (IEnumerable(Of IObservable(Of TSource)), Int32, IScheduler)

Merges an enumerable sequence of observable sequences into an observable sequence, limiting the number of concurrent subscriptions to inner sequences.

Namespace:  System.Reactive.Linq
Assembly:  System.Reactive (in System.Reactive.dll)

'Declaration
<ExtensionAttribute> _
Public Shared Function Merge(Of TSource) ( _
	sources As IEnumerable(Of IObservable(Of TSource)), _

Dim maxConcurrent As Integer
Dim scheduler As IScheduler
Dim returnValue As IObservable(Of TSource)

returnValue = sources.Merge(maxConcurrent, _
	scheduler)

Type Parameters

TSource

The type of source.

Parameters

sources
Type: System.Collections.Generic.IEnumerable(Of IObservable(Of TSource))
The enumerable sequence of observable sequences.
maxConcurrent
Type: System.Int32
The maximum number of observable sequences being subscribed to concurrently.
scheduler
Type: System.Reactive.Concurrency.IScheduler
The scheduler to run the enumeration of the sequence of sources on.

Return Value

Type: System.IObservable(Of TSource)
The observable sequence that merges the elements of the observable sequences.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable(Of IObservable(Of TSource)).
