How to convert from one type to another?

Question

ASP.NET

And here is its interface implementation:

public async Task<ProductDto> AddAsync(ProductDto item)
        {
            var product = await _unitOfWork.ProductRepository.AddAsync(item);
            return _mapper.Map<ProductDto>(product);
        }

And here is what is in unitofwork:

public async Task<Product> AddAsync(Product id)
        {
            _context.Set<Product>().Add(id);
            await _context.SaveChangesAsync();

            return id;
        }

Yes, I understand that I cannot convert ProductDto from Product. How should I do it?

Answer 1

Use the mapper or manually create a new Product and assign field values ​​from ProductDto
