Which activity would you use to repeat actions a defined number of times?

The For Each activity is used to repeat actions for each item in a collection or array. Its primary function is to iterate through a list of elements, executing the designated set of actions for each individual element encountered during the iteration. This makes it particularly useful when dealing with collections, allowing for efficient processing of each item without manually managing the indexing.

The structure of the For Each activity inherently manages the number of repetitions based on the size of the collection being iterated over. Therefore, when you need to perform the same set of actions multiple times, dependent on the number of items in a collection, this activity is ideal.

In contrast, the While activity is utilized for repeating actions as long as a specified condition remains true, which may lead to an indefinite repetition if the condition is never false. The Assign activity is primarily used for assigning values to variables, and does not involve repetition of actions. Lastly, the Invoke Workflow activity is meant for calling other workflows, which may not necessarily involve repetitive actions unless structured in a way to do so.
