Assembly:  Microsoft.ComplexEventProcessing.Observable (in Microsoft.ComplexEventProcessing.Observable.dll)

Syntax

public static ICepObservable<TOutput> Select<TInput, TOutput>(
    this ICepObservable<TInput> source,
    Expression<Func<TInput, TOutput>> selector
)

public:
generic<typename TInput, typename TOutput>
[ExtensionAttribute]
static ICepObservable<TOutput>^ Select(
    ICepObservable<TInput>^ source,
    Expression<Func<TInput, TOutput>^>^ selector
)

static member Select<'TInput, 'TOutput> : 
        source:ICepObservable<'TInput> *
        selector:Expression<Func<'TInput, 'TOutput>> -> ICepObservable<'TOutput>

<ExtensionAttribute>
Public Shared Function Select(Of TInput, TOutput) (
    source As ICepObservable(Of TInput),
    selector As Expression(Of Func(Of TInput, TOutput))
) As ICepObservable(Of TOutput)

Parameters

  The observable source to be projected. This parameter cannot be null.

• selector
  Type: System.Linq.Expressions.Expression<Func<TInput, TOutput>>

  The projection selector. This parameter cannot be null.

Return Value

Type: Microsoft.ComplexEventProcessing.Linq.ICepObservable<TOutput>
