C# Adding More Methods

Using void vs. string to print to the console

I completed this method as follows:

public void GetDisplayText()
             Console.WriteLine($"Book Title: " + Title + " Book Author: " + Author);

In the video, he used string as the return type and then used Console.WriteLine in the main program to print the string from the method.

Are both of these methods ok or is there a reason why the way he did it is preferred?

Thank you

If you're responsible for the overall design and not being given a sub-task to implement by an employer, then the final functionality is essentially the same if you output the string inside the function or back at the caller.

However, the name "GetDisplayText" implies that the function will be returning a string (and not creating any output), so a more "best practice" name for your version might be "WriteDisplayText" or "OutputDisplayText".
