Converting a model to a DTO with an operator in C#

I have a model class representing 1 entity for 1 table in the database, and I need to convert it into a DTO class to respond to the client. Usually you’d define a ToDto method to convert, or use automapper. But today I have another way, which is using the explicit operator.

Example:

namespace ConsoleApp;

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

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

public class StudentModel
{
  public string FirstName { get; set; }
  public string LastName { get; set; }
  public int YOB { get; set; }

  public static explicit operator StudentDto(StudentModel model)
  {
    return new StudentDto
    {
        Age = DateTime.Now.Year - model.YOB,
        Name = $"{model.FirstName} {model.LastName}"
    };
  }
}

public class Program
{
  static void Main(string[] args)
  {
    var studentModel = new StudentModel
    {
      YOB = 2000,
      FirstName = "Nguyen",
      LastName = "Van A"
    };

    // Using the explicit conversion
    var studentDto2 = (StudentDto)studentModel;
    Console.WriteLine(studentDto2);
  }
}
