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

using System.Linq;
…

if (myList.Any()) // we need to distinguish between empty and non-empty lists 
{
    var value = myList.First().MyMember;
    return myList.All(item => item.MyMember == value);
}
else
{
    return true;  // or false, if that is more appropriate for an empty list    
}
