使用C＃将图像插入数据库

Question

我想将图像上传到数据库（ShoppingItems）或将图像保存到项目中的文件夹中，然后将图像的路径插入db。 有人可以帮忙吗？ 这是我的代码（视图）：

@using (Html.BeginForm("Index3", "Upload", FormMethod.Post))
{
    @Html.TextBoxFor(x => x.Itemname, new { @class = "form-control", placeholder = "Item name", required = "required" })
    <br />

    @Html.TextBoxFor(x => x.Price, new { @class = "form-control", placeholder = "Item price", required = "required" })
    <br />

    @Html.TextBoxFor(x => x.Quantity, new { @class = "form-control", placeholder = "Item quantity"})
    <br />

    @Html.TextBoxFor(x => x.AuthorIdentity, new { @class = "form-control", placeholder = "Username", required = "required" })
    <br />

    // THIS IS WHERE MY IMAGE UPLOAD SHOULD BE  
    <br />

    @Html.TextBoxFor(x => x.Category, new { @class = "form-control", placeholder = "Item category", required = "required" })
    <br />

    @Html.TextAreaFor(x => x.Description, new { @class = "form-control", placeholder = "Item description", required = "required" })
    <br />

    <input type="submit" class="btn btn-danger" value="Add" />
}

控制器：

public ActionResult Index3(ShoppingItem formModel);
{
    using (var ctx = new GikGamerModelDataContext())
    {
        if (formModel == null)
            return View();

        ctx.ShoppingItems.InsertOnSubmit(formModel);
        ctx.SubmitChanges();
    }

    return View();
}

我的上传索引（Index3）仅显示表明您的上传成功或失败的文本，因此我没有添加它：)

在表单中，为了上载，您必须指定属性enctype：值为“ multipart / form-data”。您可以在此响应中尝试以下示例进行尝试： 在MVC 4中上载/显示图像
