Override the tostring method

In C#, the 'ToString()' method is inherited from the Object class, which is the base class for all types in .NET. The default implementation of 'ToString()' in the Object class returns the fully qualified name of the type. However, it may not provide meaningful information when you want to represent an object's state or data in a human-readable format.

When you override the 'ToString()' method in your custom classes, you can provide a more meaningful and customized representation of the object's data. This allows you to control what information is displayed when an object is converted to a string using 'ToString()'. Here are some reasons why you should consider overriding the 'ToString()' method:

Custom Representation: By overriding 'ToString()', you can provide a custom string representation of your object's state. This can be particularly useful for debugging, logging, or displaying object information to users.
Readability: A customized 'ToString()' method can improve the readability of your code and make it easier to understand the state of objects during development and troubleshooting.
Interoperability: Many built-in .NET classes rely on the 'ToString()' method to provide a default textual representation when working with strings, such as when displaying values in UI controls or writing to log files.
Consistency: Providing a consistent and well-defined 'ToString()' implementation for your custom classes allows other developers to know what to expect when converting objects to strings.

To override the 'ToString()' method, you need to add your own implementation within your class. Here's an example:


public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }

    public override string ToString()
    {
        return $"Name: {Name}, Age: {Age}";
    }
}

Now, when you call 'ToString()' on an instance of the 'Person' class, it will return a customized string representation containing the person's name and age.


Person person = new Person { Name = "John Doe", Age = 30 };
Console.WriteLine(person.ToString()); // Output: "Name: John Doe, Age: 30"

By overriding the 'ToString()' method, you can make your code more expressive, enhance debugging capabilities, and improve the user experience when dealing with string representations of your custom objects.
