Qbservable.Zip<TFirst, TSecond, TResult> Method (IQbservable<TFirst>, IEnumerable<TSecond>, Expression<Func<TFirst, TSecond, TResult>>)
Merges a queryable observable sequence and an enumerable sequence into one queryable observable sequence by using the selector function.

JScript does not support generic types and methods.
Type Parameters
- TFirst
The first type.
- TSecond
The second type.
- TResult
The type of result.
Parameters
- first
Type: System.Reactive.Linq.IQbservable<TFirst>
The first observable source.
- second
Type: System.Collections.Generic.IEnumerable<TSecond>
The second enumerable source.
- resultSelector
Type: System.Linq.Expressions.Expression<Func<TFirst, TSecond, TResult>>
The function to invoke for each consecutive pair of elements from the first and second source.
Return Value
Type: System.Reactive.Linq.IQbservable<TResult>
A queryable 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 IQbservable<TFirst>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
