1. Overload¶

public static IObservable<TSource> Merge<TSource>(this IObservable<IObservable<TSource>> sources)

Summary: Merges elements from all inner observable sequences into a single observable sequence.

Type parameters

Name	Description
`TSource`	The type of the elements in the source sequences.

Parameters

Name	Type	Description
`sources`	IObservable>	Observable sequence of inner observable sequences.

Returns: IObservable -- The observable sequence that merges the elements of the inner sequences.

Exceptions

Type	Condition
System.ArgumentNullException	`sources` is null.

2. Overload¶

public static IObservable<TSource> Merge<TSource>(this IObservable<Task<TSource>> sources)

Parameters

Name	Type	Description
