Change querable field in a [httpget("id")]

Question

Im using EF WEB API in ASP to interact with my SQL Database.

The API works well but id like to change the field my [HttpGet("id")] call queries - so rather returning where id =X , it returns based on another field (eg 'User')

My Model:

namespace CapabilityTrackerAPI.Models
{
public partial class Score
{
public int Id { get; set; } \\this is the primary key
public int User { get; set; }
public int SubmissionPeriod { get; set; }
public int Capability { get; set; }
public byte Score1 { get; set; }
}
}

My Controller Code:

// GET: api/Scores/5
        [HttpGet("{id}")]
        public async Task<ActionResult<Score>> GetScore(int id)
        {
            var score = await _context.Scores.FindAsync(id);

            if (score == null)
            {
                return NotFound();
            }

            return score;
        }

However rather than return the results corresponding to id - id like to retun values that match the 'User'

Any help or guidance would be very much appreciated

thanks

What I have tried:

// GET: api/Scores/5
        [HttpGet("{User}")]
        public async Task<ActionResult<Score>> GetScore(int UserId)
        {
            var score = await _context.Scores.FindAsync(UserId);

            if (score == null)
            {
                return NotFound();
            }

            return score;
        }

But that didn't work - annoyingly

Im not sure if its possible to return based on anything else other than id\Primary Key

Ive also tried

FirstOrDefaultAsync

:

// GET: api/Scores/5
        
        [HttpGet("{id}")]
        public async Task<ActionResult<Score>> GetScore(int id)
        {
            //var score = await _context.Scores.FindAsync(id);

            var score = await _context.Scores.FirstOrDefaultAsync(x => x.User == id);
            if (score == null)
            {
                return NotFound();
            }

            return score;
        }

However that only seems to return the first value - if ther are multiple values that match the criteria they are omitted..

If you want to return multiple records, then you need to change the return type of your method.

C#

[HttpGet("id")]
public async Task<ActionResult<IEnumerable<Score>>> GetScore(int id)
{
    var scores = await _context.Scores.Where(x => x.User == id).ToListAsync();
    if (scores.Count == 0) return NotFound();
    return scores;
}
