How do I execute a foreach lambda expression on ObservableCollection<T>?

There is not method of foreach with ObservableCollection<T> although this method exists with List<T>.

Is there any extension method available?

There is no method available by default in the BCL but it's straight forward to write an extension method which has the same behavior (argument checking omitted for brevity)

public static void ForEach<T>(this IEnumerable<T> enumerable, Action<T> action) {
  foreach ( var cur in enumerable ) {
    action(cur);
Use case
ObservableCollection<Student> col = ...;
col.ForEach(x => Console.WriteLine(x.Name));
                thanks for your quick reply, this is working great. but i would like to know one thing that how the predicate is working as an action? predicated: x => Console.WriteLine(x.Name)

                earlier i was using like this,  statuses.ToList().ForEach(x => x.IsHidden = true);  and i think it was just memory consuming.

public static class EnumerableExtensions
    public static void ForEach<T>(this IEnumerable<T> enumerable, Action<T> action)
        foreach (var e in enumerable)
            action(e);
