型号:
Public partial class tbl_pictures {
public int picture_id
public string picture_content
public int user_no (foreign key)
public virtual tbl_user tbl_user {get;set;}
}
视图模型:
public class MyViewModel
public IEnumerable<Telephone_Search.Models.tbl_users> users;
public IEnumerable<Telephone_Search.Models.tbl_pictures> images;
家庭控制器:
[HttpPost]
public ActionResult Index(HttpPostedFileBase file, MyViewModel model , tbl_pics pic)
{
if (ModelState.IsValid)
{
if (file != null)
{
file.SaveAs(HttpContext.Server.MapPath("~/Images/")
+ file.FileName);
byte[] data = new byte[] { };
using (var binaryReader = new BinaryReader(file.InputStream))
{
data = binaryReader.ReadBytes(file.ContentLength);
}
pic.picture_content = file.FileName;
pic.emp_no = 6;
db.tbl_pictures.Add(pic);
db.SaveChanges();
}
return RedirectToAction("Index");
}
return this.View(new MyViewModel
{
images = pic //ERROR HERE
});
}
Razor查看:
@foreach (var img in Model.images) {
<img src="~/images/@img.profile_content" width="100" height="100" />
}
@using (Html.BeginForm("Index", "Home", null, FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
<div class="editor-label">
@Html.LabelFor(model => model.picture_content)
</div>
<div class="editor-field">
<input id="ImagePath" title="Upload a product image"
type="file" name="file" />
</div>
<p><input type="submit" value="Create" /></p>
}
当我查看一个视图时,img声明它不能被隐式转换为显式转换存在? ,我的目标是在tbl_pictures中存储图像并返回一个视图模型,这样剃刀视图就可以识别存储的模型.images?
答案 0 :(得分:1)
假设tbl_pics
与tbl_pictures
相同,那么您遇到的问题就是您尝试将单个对象传递给IEnumerable
在视图模型中。
而是创建一个新的Array
,List<T>
或任何实现IEnumerable接口的东西,并用pic
填充它并将其分配给images
属性。
new MyViewModel
{
images = new Telephone_Search.Models.tbl_pictures[] { pic };
}
由于@ Matias
,使用的数组代替了List
