	Expression<Func<TSource, IEnumerable<TResult>>> selector
)

<ExtensionAttribute>

	source As IMongoQueryable(Of TSource),
	selector As Expression(Of Func(Of TSource, IEnumerable(Of TResult)))
) As IMongoQueryable(Of TResult)

[<ExtensionAttribute>]
static member SelectMany : 
        source : IMongoQueryable<'TSource> * 
        selector : Expression<Func<'TSource, IEnumerable<'TResult>>> -> IMongoQueryable<'TResult>

Parameters

source: Type: MongoDB.Driver.LinqIMongoQueryableTSource
A sequence of values to project.
selector: Type: System.Linq.ExpressionsExpressionFuncTSource, IEnumerableTResult
A projection function to apply to each element.

Type Parameters

TSource: The type of the elements of source.
TResult: The type of the elements of the sequence returned by the function represented by selector.

Return Value

Type: IMongoQueryableTResult
An IMongoQueryableT whose elements are the result of invoking a one-to-many projection function on each element of the input sequence.
