entity framework5代码首先添加图像

我正在用mvc4和entity framework5编写一个非常小的应用程序。

我想为产品添加产品，商店和图像。

我有一个模特

[Table("CatalogItem")] public class CatalogItemModel { [Key] public int CatalogItemId { get; set; } public string Description { get; set; } public double Price { get; set; } public int ProductCount { get; set; } public string Size { get; set; } public string Sku { get; set; } [Column(TypeName = "image")] public byte[] Image { get; set; } [Display(Name = "Display Catalog Item")] public bool DisplayItem { get; set; } } 

我的控制器。 这永远不会受到打击。

  [HttpPost] public ActionResult Create(CatalogItemModel catalogitemmodel) { if (ModelState.IsValid) { db.CatalogItemModels.Add(catalogitemmodel); db.SaveChanges(); return RedirectToAction("Index"); } return View(catalogitemmodel); } 

我的观点形成了

  
 
CatalogItemModel
 
 @Html.LabelFor(model => model.Description) 
 
 @Html.EditorFor(model => model.Description) @Html.ValidationMessageFor(model => model.Description) 
 
 @Html.LabelFor(model => model.Price) 
 
 @Html.EditorFor(model => model.Price) @Html.ValidationMessageFor(model => model.Price) 
 
 @Html.LabelFor(model => model.ProductCount) 
 
 @Html.EditorFor(model => model.ProductCount) @Html.ValidationMessageFor(model => model.ProductCount) 
 
 @Html.LabelFor(model => model.Size) 
 
 @Html.EditorFor(model => model.Size) @Html.ValidationMessageFor(model => model.Size) 
 
 @Html.LabelFor(model => model.Sku) 
 
 @Html.EditorFor(model => model.Sku) @Html.ValidationMessageFor(model => model.Sku) 
 
 @Html.LabelFor(model => model.DisplayItem) 
 
 @Html.EditorFor(model => model.DisplayItem) @Html.ValidationMessageFor(model => model.DisplayItem) 
 
 @Html.LabelFor(m=>m.Image) 
  
  
  

当我尝试在我的文件输入中发布带有图像的新目录时，它会引发错误

输入不是有效的Base-64字符串，因为它包含非基本64个字符，两个以上的填充字符或填充字符中的非法字符。

尝试解决这个问题：

1。 更换

with

2。 在控制器中：

  [HttpPost] public ActionResult Create(CatalogItemModel catalogitemmodel, HttpPostedFileBase ImageFile) { using (var ms = new MemoryStream()) { ImageFile.InputStream.CopyTo(ms); catalogitemmodel.Image = ms.ToArray(); } if (ModelState.IsValid) { db.CatalogItemModels.Add(catalogitemmodel); db.SaveChanges(); return RedirectToAction("Index"); } return View(catalogitemmodel); }
