What type of argument does the selector property in UiPath accept?

The selector property in UiPath accepts a System.String argument. This is because selectors are defined as strings that represent the hierarchical XML structure of UI elements in an application. The string format allows for the precise identification of elements by defining their attributes and relationships within the UI, which makes it possible for UiPath to interact with those elements accurately.

By using a System.String, users can create complex selectors that might include wildcards, variables, and specific attributes to match different elements dynamically. This flexibility is essential for building robust automations, as it allows the RPA workflows to adjust to changes in the UI or application layout.

Using other data types like System.Int32, System.Boolean, or System.Object would not serve the purpose of selectors. An integer or boolean does not have a structure that can represent the necessary UI element data, while System.Object would not specifically define the type of data needed for a selector, which is explicitly a string that points to UI components.
