博客模态类应具有Img字段；

Blog Modal Class should have Img field like;

    public int BlogId{ get; set; }
    ...
    public byte[] Img{ get; set; }

控制器;

    public async Task<IActionResult> Create([Bind("BlogId,...Img")] Blog blog t, IFormFile Image)
    if (ModelState.IsValid)
        {
            if (Image!= null)

            {
                if (Image.Length > 0)

                //Convert Image to byte and save to database

                {

                    byte[] p1 = null;
                    using (var fs1 = Image.OpenReadStream())
                    using (var ms1 = new MemoryStream())
                    {
                        fs1.CopyTo(ms1);
