Question

I have:

List A  = new List(){1,2,3,4,5,6};

List m=new List();
for(int i=1;i

        

Answer 1

Ok so getting the Next item in the list you can use:

A.SkipWhile(x => x != value).Skip(1).FirstOrDefault();

So to get the previous item use:

var B = A.ToList();
B.Reverse();
B.SkipWhile(x => x != value).Skip(1).FirstOrDefault();
