ForAll3

TTests if all corresponding elements of the collection satisfy the given predicate.

If any application returns false then the overall result is false and no further elements are tested. Otherwise, true is returned.

WARNING

This function causes IEnumerable<T> evaluation.

Usage

Checking if all elements of all collections are equals

//IEnumerable<int> source =  { 4, 2, 6, 8, 10 }
//IEnumerable<int> source2 = { 4, 2 }
//IEnumerable<int> source3 = { 4, 2 }

bool result = 
    source.ForAll3(
        source2,
        source3, 
        (element1, element2,element3) => element1 == element2
                                      && element2 == element3);

//result = true

//IEnumerable<int> source =  { 4, 2, 6, 8, 10 }
//IEnumerable<int> source2 = { 4, 2, 5 }
//IEnumerable<int> source3 = { 4, 2, 5 }

bool result = 
    source.ForAll3(
        source2,
        source3, 
        (element1, element2,element3) => element1 == element2
                                      && element2 == element3);

//result = false
