When using the "Find Children" activity in UiPath, what is the type of variable used to store the output?

The "Find Children" activity in UiPath is designed to search for and retrieve a collection of child UI elements of a specified parent element. The output of this activity is stored in a variable that can manage a sequence of multiple elements.

The correct type of variable to store this output is IEnumerable. This type allows for the storage of a collection of UI elements (represented as UiElement objects) that can be enumerated over, which is essential for any further interactions or activities that may be performed on the identified child elements.

Using IEnumerable enables developers to efficiently work with a subset of UI elements, supporting the manipulation and interaction with these elements in a manner that aligns with the practices of automation in UiPath. This collection can represent zero or more child elements, providing flexibility for various automation scenarios.

In contrast, array, string, and integer types are not appropriate here. An array does not inherently support the same level of enumeration flexibility that IEnumerable does, while a string is a single piece of text, and an integer represents a numeric value, neither of which can accommodate a collection of UI elements.
