Zip(TFirst, TSecond, TResult) Method (IObservable(TFirst), IObservable(TSecond), Func(TFirst, TSecond, TResult))

Observable.Zip(TFirst, TSecond, TResult) Method (IObservable(TFirst), IObservable(TSecond), Func(TFirst, TSecond, TResult))

Merges two observable sequences into one observable sequence by combining their elements in a pairwise fashion.

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

static member Zip : 
        first:IObservable<'TFirst> * 
        second:IObservable<'TSecond> * 
        resultSelector:Func<'TFirst, 'TSecond, 'TResult> -> IObservable<'TResult> 

Type Parameters

TFirst

The first type.

TSecond

The second type.

TResult

The type of result.

Parameters

first
Type: System.IObservable(TFirst)
The first observable source.
second
Type: System.IObservable(TSecond)
The second observable source.
resultSelector
Type: System.Func(TFirst, TSecond, TResult)
The function to invoke for each consecutive pair of elements from the first and second source.

Return Value

Type: System.IObservable(TResult)
An observable sequence containing the result of pairwise combining the elements of the first and second source using the specified result selector function.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IObservable(TFirst). When you use instance method syntax to call this method, omit the first parameter.
