1. Overload

Attributes: [Experimental]

public static IObservable<TResult> ForkJoin<TSource1, TSource2, TResult>(this IObservable<TSource1> first, IObservable<TSource2> second, Func<TSource1, TSource2, TResult> resultSelector)

Summary: Runs two observable sequences in parallel and combines their last elements.

Type parameters

Name	Description
`TSource1`	The type of the elements in the first source sequence.
`TSource2`	The type of the elements in the second source sequence.
`TResult`	The type of the elements in the result sequence, returned by the selector function.

Parameters

Name	Type	Description
`first`	IObservable	First observable sequence.
`second`	IObservable	Second observable sequence.
`resultSelector`	Func	Result selector function to invoke with the last elements of both sequences.

Returns: IObservable -- An observable sequence with the result of calling the selector function with the last elements of both input sequences.

Exceptions

Type	Condition
System.ArgumentNullException	`first` or `second` or `resultSelector` is null.

2. Overload

Attributes: [Experimental]

public static IObservable<TSource[]> ForkJoin<TSource>(params IObservable<TSource>[] sources)

Summary: Runs all specified observable sequences in parallel and collects their last elements.

Type parameters

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

Parameters

Name	Type	Description
`params sources`	`IObservable<TSource>[]`	Observable sequence to collect the last elements for.

Returns: IObservable -- An observable sequence with an array collecting the last elements of all the input sequences.

Exceptions

Type	Condition
System.ArgumentNullException	`sources` is null.

3. Overload

Attributes: [Experimental]

public static IObservable<TSource[]> ForkJoin<TSource>(this IEnumerable<IObservable<TSource>> sources)

Summary: Runs all observable sequences in the enumerable sources sequence in parallel and collect their last elements.

Type parameters

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

Parameters

Name	Type	Description
`sources`	IEnumerable>	Observable sequence to collect the last elements for.

Returns: IObservable -- An observable sequence with an array collecting the last elements of all the input sequences.

Exceptions

Type	Condition
System.ArgumentNullException	`sources` is null.
