推荐答案

亲爱的Mahmud，



您可以使用HttpPostedFileBase。 InputStream.Read（）方法将上传流读取到缓冲区，然后将其保存到数据库字段中。例如：

Dear Mahmud,

You can use HttpPostedFileBase.InputStream.Read() method read the upload stream to a buffer, and then save it to the database field. For example:

[HttpPost]
        public ActionResult Create(string fileTitle)
        {
            try
            {
                HttpPostedFileBase file = Request.Files[0];
                byte[] imageSize = new byte[file.ContentLength];
                file.InputStream.Read(imageSize, 0, (int)file.ContentLength);
                Image image = new Image()
                {
                    Name = file.FileName.Split('\\').Last(),
                    Size = file.ContentLength,
                    Title = fileTitle,
                    ID = 1,
                    Image1 = imageSize
                };
                db.Images.AddObject(image);
                db.SaveChanges();
                return RedirectToAction("Detail");
            }
            catch(Exception e)
            {
                ModelState.AddModelError("uploadError", e);
            }
            return View();
        }

查看

View

  @using (Html.BeginForm("Create", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <fieldset>
        <legend>Upload Image</legend>

        @Html.Label("Title")
        @Html.Editor("fileTitle")<br />
        Upload File: <input type="file" name="test" />
        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

我认为这会对你有所帮助



谢谢
