update multiple elements at once LINQ

Question

Is it possible to set property on each element from List using LINQ.

for example:

var users = from u in context.Users where u.Name == \"George\" sele         


        

Answer 1

You can create your own ForEach extension method:

public static IEnumerable ForEach(this IEnumerable source, Action action)
{
    foreach (var element in source)
    {
        action(element);
    }

    return source;
}

Then your code can be simplified to:

context.Users.Where(x => x.Name == "George").ForEach(u => u.MyProp = false);

EDIT: You could also yield return each item after the call to action() (no pun intended) to leave the deferred execution untouched.
