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.

Parameters	Returns
Func<T, T2, T3, bool> predicate IEnumerable<T> source IEnumerable<T2> source2 IEnumerable<T3> source3	bool

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
