What is the Control class property that can be set to identify objects with a string expression?

The Tag property of a Control class is designed to store a string expression that provides additional information about an object. This property can be very useful for identifying controls or storing custom values that relate to the control without needing to create additional variables. By using the Tag property, developers can associate specific data with a control, making it easier to retrieve that information later, especially in events like button clicks or during processing tasks where specific control data may need to be accessed.

The Tag property is versatile, allowing any string value to be stored, which can represent identifiers, descriptions, or any other relevant information that helps in managing the controls within an application. This feature enhances the organization and readability of code by associating meaningful data directly with its corresponding control.

In contrast, the other choices do not serve the same purpose as the Tag property:

• The Identifier does not exist as a standard property within the Control class in most frameworks.
• ObjectName is not a recognized property of controls and does not typically pertain to string identification.
• Label refers to a specific type of control often used to display text, rather than a property that can identify controls with a string expression.

Thus, the Tag property is the most fitting choice for the purpose of identifying objects with a string
