c# - 如何在 ASP.net MVC 的文件夹中显示保存的图像

Question

我正在将图像文件保存在文件夹/images/profile 中，我想将图像路径保存在数据库中，但不知道如何在 View 中显示图像。我是 MVC 的新手。以下是图片上传的代码。请帮忙。

HomeController.cs

public class HomeController : Controller
    {

        ImageEntities db = new ImageEntities();
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult FileUpload(HttpPostedFileBase file, tbl_Image model)
        {
            if (file != null)
            {
                string pic = System.IO.Path.GetFileName(file.FileName);
                string path = System.IO.Path.Combine(
                                       Server.MapPath("~/images/profile"), pic);
                // file is uploaded
                file.SaveAs(path);

            }

    return View("FileUploaded", db.tbl_Image.ToList());

        }

        public ActionResult FileUploaded()
        {
            return View();
        }

    }

文件上传.cshtml

@using (Html.BeginForm("FileUpload", "Home", FormMethod.Post, 
                            new { enctype = "multipart/form-data" }))
{  
    <label for="file">Upload Image:</label> 
    <input type="file" name="file" id="file" style="width: 100%;" /> 
    <input type="submit" value="Upload" class="submit" /> 
}

文件上传 View .cshtml

@foreach (var item in Model)
    { 
   <img src="~/images/profile/@item.imagepath" />
    }

您应该在表中保存图像名称 而不是图像路径。

然后在 View 中试试这个:

<img src="~/images/profile/@Model.imageUrl" />
