Executing a certain action for all elements in an Enumerable

Question

I have an Enumerable and am looking for a method that allows me to execute an action for each element, kind of like Select but then for si

Answer 1

You cannot do this right away with LINQ and IEnumerable - you need to either implement your own extension method, or cast your enumeration to an array with LINQ and then call Array.ForEach():

Array.ForEach(MyCollection.ToArray(), x => x.YourMethod());

Please note that because of the way value types and structs work, if the collection is of a value type and you modify the elements of the collection this way, it will have no effect on the elements of the original collection.
