Check if all List Items have the same member value in C#

Question

I\'m searching for a simple and fast way to check if all my Listitems have the same value for a member.

foreach (Item item in MyList)
{
    Item.MyMember = &         


        

Answer 1

I think this is the shortest and most elegant solution:

bool allSame = list.GroupBy(item => item.TheProperty).Count == 1;
