what is wrong with my mapping in csharp

To determine what is wrong with your mapping in C#, you should first check if you have correctly defined the mappings for each attribute you are trying to map.

You could also use a debugging tool such as Visual Studio's Debugger to step through your code and see how your mappings are working.

Here's an example of how to debug a mapping scenario in C#:

main.cs
using AutoMapper;

// Define classes
public class Student {
    public int ID { get; set; }
    public string Name { get; set; }
    public string Grade { get; set; }
}

public class StudentDTO {
    public int ID { get; set; }
    public string Name { get; set; }
    public string Grade { get; set; }
}

// Define mapping profile
public class StudentProfile : Profile {
    public StudentProfile() {
        CreateMap<Student, StudentDTO>();
    }
}

// Use mapping profile
class Program {
    static void Main(string[] args) {
        var configuration = new MapperConfiguration(cfg => cfg.AddProfile<StudentProfile>());
        IMapper mapper = new Mapper(configuration);

        var student = new Student() { ID = 1, Name = "John Doe", Grade = "A" };
        var studentDto = mapper.Map<StudentDTO>(student);

        Console.WriteLine(studentDto.Name);
    }
}

In this example, we are using AutoMapper to map a Student object to a StudentDTO object. We first define the classes, then create a mapping profile that maps the Student object to the StudentDTO object.

We then use the mapping profile and the Mapper class to map a Student object to a StudentDTO object, and print out the name of the StudentDTO object to the console.

By using a debugging tool like Visual Studio's Debugger, you can step through your code and see if the mappings are working as intended and identify any issues with your code.
