OneResult

OneResult is a simple library that provides an output model which can be used as an output result for methods. By using OneResult, all methods in each layer, return same Model.

Install OneResult

Install-Package OneResult -Version 1.0.0

how to use OneResult.

OneResult contains one main model which name is ActionResult. below are some examples to help you know how to use it.

If everything goes fine, you just need to return Success as below:

return ActionResult.Success();

If something goes wrong, you can return Failed ActionResult as below;

return ActionResult.Failed();

You also can add error details while returning Failed:

return ActionResult.Failed(new ActionError { Code = "404", Description = "bookmark does not exists" });

Return success and Error by OneResult

First, add OneResult namespace

using OneResult;

Below is a real usage of ActionResult :

  public ActionResult Delete(int id)
    {
        var bookmark =  _dbContext.Bookmarks.FirstOrDefault(b => b.Id == id);
        if (bookmark == null)
            return ActionResult.Failed(new ActionError { Code = "404", Description = "bookmark does not exists" });
        _dbContext.Bookmarks.Remove(bookmark);
         _dbContext.SaveChanges();
        return ActionResult.Success();
    }

ActionResult and Return Data

If your methods need to return data (one or more records), you can define ActionResult like below:

public ActionResult<BookmarkEntity> Get(int id)
    {
        var bookmark = _dbContext.Bookmarks.FirstOrDefault(b => b.Id == id);
        return ActionResult<BookmarkEntity>.Success(bookmark);
    }

also possible to return List<T> like this method:

 public ActionResult<IEnumerable<BookmarkEntity>> GetAll()
    {
        var bookmarks = _dbContext.Bookmarks.ToList();
        return ActionResult<IEnumerable<BookmarkEntity>>.Success(bookmarks);
    }

Use ActionResult with MediatR

If you are using MediatR, it's possible to use OneResult in order to have Just one Output model.

ActionResult and Commands

 public class CreateBookmarkCommand : IRequest<ActionResult<BookmarkDto>>
{
    public string Path { get; init; }
    public Browser Browser { get; init; }
    public int UserId { get; init; }

}

 public class CreateBookmarkCommandHandler : IRequestHandler<CreateBookmarkCommand, ActionResult<BookmarkDto>>
{

    public async Task<ActionResult<BookmarkDto>> Handle(CreateBookmarkCommand request, CancellationToken cancellationToken)
    {
       // rest of implementation
        return ActionResult<BookmarkDto>.Success(dto);
    }
}
