Properties or Methods: When Should You Use Which?

Selection of attributes and methods

In software development, we often encounter the problem of whether to use attributes or methods. This article will guide you when to use each method, with specific reference to the examples provided.

Decision Criteria

As mentioned in the Class Library Development Design Guide, properties are generally used to represent data, while methods represent operations. Properties are designed for simple data retrieval or manipulation, similar to fields, and should avoid complex calculations or side effects.

Sample Assessment

In the provided example, the SetLabel method is only responsible for setting the text of the control. This operation does not perform any complex calculations or produce side effects. Therefore, according to the above guidelines, it is more appropriate to express its functionality as a property rather than a method.

Advantages of using attributes

Selecting attributes in this case has several advantages:

• Simplicity: The properties themselves are easier to understand and use, especially for less experienced developers.
• Readability: Attributes enhance code readability by presenting data in a clear and concise way.
• Maintainability: Properties simplify code maintenance by centralizing data access and manipulation.

Conclusion

Developers should consider the intended functionality when deciding to use properties or methods. Properties are great for data representation, while methods are better suited for operations involving calculations or side effects. In the example provided, the SetLabel operations are best implemented as properties to ensure ease of use, clarity, and maintainability.
