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.)

It’s a .net concept, you can find full details here:

Enumerable Class (System.Linq)

What is the concept of IEnumerable <object> variable for Read Column?

Hi, To keep it simple, if your object implement IEnumerable, you can iterate over it (with a ForEach). In other words, if something gives you an IEnumerable it provides you a mean to have its elements one by one. 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
Thanks

Hi,

FYI, the following also helps you.

DataTableExtensions.AsEnumerable(DataTable) Method (System.Data)

At first, as DataTable.Rows returns DataRowCollection, LINQ cannot be applied to it. To solve this matter, Microsoft added this method in DataTableExtensions.
