Map2

Builds a new collection whose elements are the results of applying the given mapping function to the corresponding elements of the two collections pairwise.

Parameters	Returns
Func<T, T2, TResult> mapping IEnumerable<T> source IEnumerable<T2> source2	IEnumerable<TResult>

Usage

Multiplying the sum of each pair of values by two

//IEnumerable<int> source = { 1, 2, 3, 4, 5 }
//IEnumerable<int> source2 = { 5, 3, 3, 3, 0 }

IEnumerable<int> result = 
    source.Map2(
        source2, 
        (value1, value2) => (value1 + value2) * 2);

//result = { 12, 10, 12, 14, 0}
