Is it possible to use LINQ to check if all numbers in a list are increasing monotonically?

Question

I\'m interested if there is a way, in LINQ, to check if all numbers in a list are increasing monotonically?

Example

List l         


        

Answer 1

If you want to check whether a list always is increasing from index to index:

IEnumerable list = new List() { 1, 2, 3, 4, 5, 6, 7, 10 };
bool allIncreasing = !list
    .Where((i, index) => index > 0 && list.ElementAt(index - 1) >= i)
    .Any();

Demo

But in my opinion a simple loop would be more readable in this case.
