Qbservable.Multicast<TSource, TIntermediate, TResult> Method

Returns a queryable observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.

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

Type Parameters

  • TSource
    The type of source.

  • TIntermediate
    The type of intermediate.

  • TResult
    The type of result.

Parameters

Return Value

Type: System.Reactive.Linq.IQbservable<TResult>
A queryable observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IQbservable<TSource>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
