Question 9

Explanation

The following methods can be used to populate the target list:

• Initiate the variable with New List(of String) and use Add To Collection activities to populate the list.

• Set the Default value in the Variables panel to New List(of String) from {"BTC", "ETH", "USDT", "XRP"}

Manipulating lists can be done using .NET methods or using the collection methods that UiPath Studio offers:

Add to Collection

Adds an item to a specified collection. It is equivalent to List.Add(). It can be used, for example, to add a new name to a list of company names.

Remove from Collection

Removes an item from a specified collection and can output a Boolean variable that confirms the success of the removal operation. This activity can be used, for example, to remove an invoice number from a list of invoices to be processed.

Exists in Collection

Indicates whether a given item is present in a given collection by outputting a Boolean as the result. We can use this activity to check whether a list of clients contains a specific name.

Clear Collection

Clears a specified collection of all items. One possible use is to empty a collection before starting a new phase of a process that will populate it again.

The Variables Panel

The Variables panel enables you to create variables and make changes to them. Renaming a variable in this panel automatically updates all occurrences in the current file.
