Suggestions for printing arrays with record ToString

[bunnyi116]

Example：

Person person = new("Nancy", "Davolio")
{
    PhoneNumbers = new string[] { "123", "456" }
};

Console.WriteLine(person);

// Result
//  original: Person { FirstName = Nancy, LastName = Davolio, PhoneNumbers = System.String[] }
//  hope    : Person { FirstName = Nancy, LastName = Davolio, PhoneNumbers = [ 123, 456 ] }

record Person(string FirstName, string LastName)
{
    public string[] PhoneNumbers { get; init; } = Array.Empty<string>();
};

Result

original

Person { FirstName = Nancy, LastName = Davolio, PhoneNumbers = System.String[] }

hope

Person { FirstName = Nancy, LastName = Davolio, PhoneNumbers = [ 123, 456 ] }

Suggestion

I want the compiler to print out the contents of the array in the ToString in the record class, so that you can see the contents of the array more intuitively

@Bunnui by default the compiler always just defers to the specific type to control all these things (equality, hasing, printing, etc.)

If you want to customize this, you can override the appropriate members in your record to do so.

To expand, I believe it would be possible for a source generator to fill in the gap here. It could detect an [ArraySensitiveToString] attribute and generate the (entire) custom ToString overload for you.
