Grouping.selectMany Method
Projects each element of this sequence to an enumerable, 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.
Parameters
- collectionSelector
-
Type: Function
A transform function to apply to each source element; the second parameter of the function
represents the index of the source element.
- resultSelector
-
Type: Function
A transform function to apply to each element of the intermediate sequence.
Optional: True
Return Value
Type: IEnumerable
An enumerable whose elements are the result of invoking the one-to-many transform function
collectionSelector on each element of source and then
mapping each of those sequence elements and their corresponding source element to a result
element.
