如何使用.Net MVC将上传的图片保存到数据库中并在视图中显示

public class ImageModel
{
    public int Id { get; set; }
    public string FileName { get; set; }
    public string FileType { get; set; }
    public byte[] FileData { get; set; }
}

@using (Html.BeginForm("Upload", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <input type="file" name="imageFile" />
    <input type="submit" value="Upload" />
}

@if (Model != null && Model.FileData != null)
{
    <img src="@Url.Action("Display", "Home", new { id = Model.Id })" alt="Uploaded Image" />
}

public class HomeController : Controller
{
    public ActionResult Upload()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Upload(HttpPostedFileBase imageFile)
    {
        if (imageFile != null && imageFile.ContentLength > 0)
        {
            byte[] fileData = null;
            using (var binaryReader = new BinaryReader(imageFile.InputStream))
            {
                fileData = binaryReader.ReadBytes(imageFile.ContentLength);
            }

            ImageModel image = new ImageModel
            {
                FileName = imageFile.FileName,
                FileType = imageFile.ContentType,
                FileData = fileData
            };

            // 将image保存到数据库中，此处省略数据库操作代码

            return View(image);
        }

        return View();
    }

    public FileContentResult Display(int id)
    {
        // 从数据库中获取图片信息，此处省略数据库操作代码
        ImageModel image = GetImageFromDatabase(id);

        if (image != null)
        {
            return File(image.FileData, image.FileType);
        }

        return null;
    }
}
