如何通过PUT方法更新ICollection的属性？

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public decimal Price { get; set; }
}

public class ProductCollection : ICollection<Product>
{
    private List<Product> products = new List<Product>();

    // 实现ICollection接口的方法
    public int Count => products.Count;
    public bool IsReadOnly => false;

    public void Add(Product item) => products.Add(item);
    public void Clear() => products.Clear();
    public bool Contains(Product item) => products.Contains(item);
    public void CopyTo(Product[] array, int arrayIndex) => products.CopyTo(array, arrayIndex);
    public bool Remove(Product item) => products.Remove(item);
    public IEnumerator<Product> GetEnumerator() => products.GetEnumerator();
    IEnumerator IEnumerable.GetEnumerator() => GetEnumerator();

    // 自定义方法用于更新产品
    public bool UpdateProduct(int id, Product updatedProduct)
    {
        var product = products.FirstOrDefault(p => p.Id == id);
        if (product != null)
        {
            product.Name = updatedProduct.Name;
            product.Price = updatedProduct.Price;
            return true;
        }
        return false;
    }
}

[ApiController]
[Route("api/[controller]")]
public class ProductsController : ControllerBase
{
    private readonly ProductCollection _productCollection = new ProductCollection();

    [HttpPut("{id}")]
    public IActionResult UpdateProduct(int id, [FromBody] Product updatedProduct)
    {
        if (_productCollection.UpdateProduct(id, updatedProduct))
        {
            return NoContent(); // 204 No Content
        }
        return NotFound(); // 404 Not Found
    }
}
