The Invoke Method activity is used to invoke a method of a class or an object. In this case, the developer wants to add items to a list of strings using the Invoke Method activity. The list is declared as follows:

Dim Colors As New List(Of String)

This means that the list is named Colors and it can store strings. The Invoke Method activity has the following properties:

TargetType: System.Collections.Generic.List`1[System.String]. This means that the target type is a generic list of strings.

TargetObject: Colors. This means that the target object is the list named Colors.

MethodName: Add. This means that the method name is Add, which is a method of the list class that adds an item to the end of the list.

Parameters: In, String, Yellow. This means that the parameter direction is In, which means that the value is passed to the method. The parameter type is String, which means that the value is a string. The parameter value is Yellow, which means that the value is the string “Yellow”.

Based on the information shown in the exhibits, the outcome of the Invoke Method activity is that Colors will contain an item with the value “Yellow”. This is because the Invoke Method activity will add “Yellow” to the list of strings declared as Colors.
