Parameters

source: Type: System.Linq IQueryable TSource
The sequence of input elements

selector: Type: System.Linq.Expressions Expression Func TSource, Int64, IEnumerable TCollection
A transform function to apply to each source element; the second parameter of the function represents the index of the source element.

resultSelector: Type: System.Linq.Expressions Expression Func TSource, TCollection, TResult
A transformation function to apply to each intermediate element

Type Parameters

TSource: The type of the elements of source
TCollection: The type of the element in the intermediate IEnumerable sequences
TResult: The type of the elements of the result

Return Value

Type: IQueryable TResult
The sequence resulting from applying

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IQueryable 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).
