'Usage
Dim source As IQbservable(Of TSource)
Dim sampler As IObservable(Of TSample)
Dim returnValue As IQbservable(Of TSource)

returnValue = source.Sample(sampler)

    IObservable<TSample> sampler
)

[ExtensionAttribute]
public:
generic<typename TSource, typename TSample>
static IQbservable<TSource>^ Sample(
    IQbservable<TSource>^ source, 
    IObservable<TSample>^ sampler
)

        sampler:IObservable<'TSample> -> IQbservable<'TSource> 

JScript does not support generic types and methods.

Type Parameters

• TSource
  The type of source.

• TSample
  The type of sample.

Parameters

• source
  Type: System.Reactive.Linq.IQbservable<TSource>
  The source sequence to sample.

• sampler
  Type: System.IObservable<TSample>
  The sampling tick sequence.

Return Value

Type: System.Reactive.Linq.IQbservable<TSource>
The sampled queryable observable sequence.
