Observable.Merge<TSource> Method (IEnumerable<IObservable<TSource>>, Int32)

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)

JScript does not support generic types and methods.

Type Parameters

  • TSource
    The type of source.


  • maxConcurrent
    Type: System.Int32
    The maximum number of observable sequences being subscribed to concurrently.

Return Value

Type: System.IObservable<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<IObservable<TSource>>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
