✅ Is it possible to override ToString method for Anonymous type in C#? (Not using overriden one)

Hello guys, just wondering if it was possible to use another implementation of the ToString method for anonymous type. I was just using LINQ to perform the following:

C#
var lessons = context.Lessons.Select(lessons => new
            {
                StudentFirstName = lessons.Student.FirstName,
                StudentLastName = lessons.Student.LastName,
                StudentEmail = lessons.Student.Email,
                InstructorFirstName = lessons.Instructor.FirstName,
                InstructorLastName = lessons.Instructor.LastName,
                InstructorEmail = lessons.Instructor.Email,
                CarTransmission = lessons.Car.Transmission,
                LessonDate = lessons.Date
            });

C#
var lessons = context.Lessons.Select(lessons => new
            {
                StudentFirstName = lessons.Student.FirstName,
                StudentLastName = lessons.Student.LastName,
                StudentEmail = lessons.Student.Email,
                InstructorFirstName = lessons.Instructor.FirstName,
                InstructorLastName = lessons.Instructor.LastName,
                InstructorEmail = lessons.Instructor.Email,
                CarTransmission = lessons.Car.Transmission,
                LessonDate = lessons.Date
            });

When I use a foreach and output each lesson, I have the overriden format of the ToString method. I manage to change part of it using the following:

C#
Console.WriteLine(lesson.ToString().Replace("{","").Replace("}","").TrimStart());

C#
Console.WriteLine(lesson.ToString().Replace("{","").Replace("}","").TrimStart());

But just wanted to know if it's actually possible to change the ToString format again

You cannot.

rip, noted, thanks ! The "best" solution would be to create a class of what I want to project?

Yes, a record will be nice and concise.
