Parameters
- source
- Type: Sequences ISequence TSource
A sequence of values to project.
- selector
- Type: System Func TSource, IEnumerable TResult
A transform 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 selector.
Return Value
Type:
ISequence TResult A sequence whose elements are the result of invoking the one-to-many transform function on each element of the input sequence.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
ISequence TSource . When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
