Exam UiPath-ADPv1 Topic 1 Question 28 Discussion

The screenshot shows an "Invoke Code" activity in UiPath with the following VB.NET code:
Users_List.Add("User1")
Users_List.Add("User2")
According to the given information, the "Users_List" variable is a List of Strings that has been initialized with an empty list before the Invoke Code activity is run. The code within the Invoke Code activity is adding two strings: "User1" and "User2" to the "Users_List".
The Log Message activity following the Invoke Code is attempting to log the count of items in "Users_List", which would be the number of elements contained in the list at that time.
Given the steps that have been described, after the Invoke Code activity has run, the "Users_List" will contain two elements ("User1" and "User2"). Therefore, the log message will print the count of items in the list, which is:
B: 2
So the correct answer is B, as the "Users_List" will have two elements and Users_List.Count will return the number 2.
The Invoke Code activity is used to execute VB.NET or C# code within a UiPath workflow1. The activity has the following properties:
* Code: The code that is to be executed. This field supports only strings and String variables1.
* Language: The language that the code is written in. The available options are VBNet and CSharp1.
* Arguments: The parameters that can be passed to and from the code1.
In this question, the developer has created a variable of type List of Strings named "Users_List", and initialized it with an empty list: "Users_List = new List(Of String)". Then, the developer has used the Invoke Code activity to execute the following code:
Users_List.Add("User1") Users_List.Add("User2")
This code adds two items ("User1" and "User2") to the "Users_List" variable. After the Invoke Code activity, the developer has used the Log Message activity to print the count of items in the "Users_List" variable, using the expression "Users_List.Count.ToString". This expression returns the number of items in the list as a string2. Therefore, the log message will print "2", as there are two items in the list
