Returns a connectable observable sequence that upon connection causes the source sequence to push results into the specified subject.

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

Syntax

Public Shared Function Multicast(Of TSource, TResult) ( _
    source As IObservable(Of TSource), _

'Usage
Dim source As IObservable(Of TSource)

[ExtensionAttribute]

JScript does not support generic types and methods.

Type Parameters

  • TSource
    The type of source.
  • TResult
    The type of result.

Parameters

  • source
    Type: System.IObservable<TSource>
    The source sequence whose elements will be pushed into the specified subject.

Return Value

Type: System.Reactive.Subjects.IConnectableObservable<TResult>
A connectable observable sequence that upon connection causes the source sequence to push results into the specified subject.

Usage Note

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