Hi @Alvin_Apostol3
To know what an enumerable is, you must understand the verb/action enumerate. The definition of enumerate is: “mention (a number of things) one by one.”

An enumerable is just a read-only object that you can enumerate over. This means it is a collection of any type of variables that you can go through one-by-one. Since it is read-only, you can’t change the enumerable itself, you just read the information from it. This makes it the least resource intensive type of collection to iterate through (vs list, array, etc.)

I’m quite new to VB and .NET (for UiPath purposes) but I’m quite sure that ForEach expects that the objects it iterate over implement IEnumerable and an object implementing IEnumerable is able to give next element and tell that the end is reached. Implementing an Interface is like sw…

Hope this helps
