We have an entity type class that when it is converted to its dto class, I want a property to be set with additional calculations. Entity class:

 public class Student
{
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string  LastName { get; set; }
    public byte Score { get; set; }
}

Dto class:

public class StudentRankingDto
{
        
    public int Id { get; set; }
    public string Name { get; set; }  // FirstName +" " +LastName
    public string Rank { get; set; }
}

In Dto class, the rank attribute value is calculated based on a dictionary.

dictionary :

 Dictionary<byte,string> Ranks { get; set; } = new Dictionary<byte, string>() 
{
    {0,"rejected" },
    {1,"very weak" },
    {2,"very weak" },
    {3,"weak" },
    {4,"weak" },
    {5,"medium" },
    {6,"medium" },
    {7,"Good" },
    {8,"Good" },
    {9,"Excellent" },
    {10,"Excellent" }
};

And considering that the dictionary may change later due to the logic of the program and it is necessary not to have a fixed dictionary inside Automapper and this dictionary must be sent to Automapper. Now my question is: how to assign the rank attribute based on the student’s score in Automapper by sending this dictionary?

And a more general question. If the value of the property to be calculated should be obtained from a database table, how is it possible to inject the database into Automapper with ef Core?

I tried to send an object based on the Automapper guide but it didn’t work
