Enumerable.SelectMany (this IEnumerable<TSource>, Func<TSource, IEnumerable<TCollection>>, Func<TSource, TCollection, TResult>) 

Projects each element of a sequence to an IEnumerable{T}, flattens the resulting sequences into one sequence, and invokes a result selector function on each element therein.  

 

Enumerable.SelectMany (this IEnumerable<TSource>, Func<TSource, IEnumerable<TResult>>) 

Projects each element of a sequence to an IEnumerable{T} and flattens the resulting sequences into one sequence.  

 

Enumerable.SelectMany (this IEnumerable<TSource>, Func<TSource, int, IEnumerable<TCollection>>, Func<TSource, TCollection, TResult>) 

Projects each element of a sequence to an IEnumerable{T}, flattens the resulting sequences into one sequence, and invokes a result selector function on each element therein. The index of each source element is used in the intermediate projected form of that element.
