大佬教程收集整理的这篇文章主要介绍了asp.net-mvc – MVC：如何将文件上传和其他表单字段发布到一个操作，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
Html.beginForm("Create","Document",FormMethod.Post,enctype = "multipart/form-data")
和
Html.beginForm()
我的看法如下：
<%@ Page title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Publications.WebUI.Models.DocumentEditViewModel >" %> <asp:Content ID="Content1" ContentPlaceHolderID="titleContent" runat="server"> Edit </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <fieldset> <legend>Edit <%= Html.Truncate(Model.Document.title,50)%></legend> <%= Html.ValidationSumMary(false) %> <% using (Html.beginForm()) { %> <div class="editor-label"> <%= Html.LabelFor(model => model.Document.titlE) %> </div> <div class="editor-field"> <%= Html.HiddenFor(model => model.Document.DocumentId ) %> <%= Html.ValidationmessageFor(model => model.Document.titlE) %> <%= Html.TextBoxFor(model => model.Document.titlE)%> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Document.DocumentUrl)%> </div> <div class="editor-field"> <%= Html.ValidationmessageFor(model => model.Document.DocumentUrl)%> <%= Html.TextBoxFor(model => model.Document.DocumentUrl)%> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Document.Description)%> </div> <div class="editor-field"> <%= Html.ValidationmessageFor(model => model.Document.Description)%> <%= Html.TextAreaFor(model => model.Document.Description) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Document.ThumbnailUrl )%> </div> <div class="editor-field"> <% using (Html.beginForm("Create",new { enctype = "multipart/form-data" })) {%> <%= Html.ValidationmessageFor(model => model.Document.ThumbnailUrl )%> <input name="uploadFile" type="file" /> <% } %> </div> <div class="formActions"> <div class="BACkNav"> <%= Html.ActionLink("< BACk to List","Index") %> </div> <div class="submit"> <input type="submit" value="Save" /> </div> <% } %> </div> </fieldset> </asp:Content>
我的控制器只需要使用Document模型和httpPostedFileBase，并尝试将文件上传到服务器并将文档保存到存储库
[httpPost] public ActionResult Create(Document document,httpPostedFileBase uploadFilE) { if (ModelState.IsValid) { //Process file upload //update repository } return View("List"); }
所以我想知道是否可以做同样的操作的文件上传和更新存储库，我应该如何构造我的视图来促进这一点。
视图
<asp:Content ContentPlaceHolderID="MainContent" runat="server">
<h1>Edit <%= Model.Name %></h1>
<% using (Html.beginForm("Edit","Admin",new { enctype = "multipart/form-data" })) { %>
<%= Html.Hidden("ProductID") %>
<p>
Name: <%= Html.TextBox("Name") %>
<div><%= Html.Validationmessage("Name") %></div>
</p>
<p>
Description: <%= Html.TextArea("Description",null,4,20,null) %>
<div><%= Html.Validationmessage("Description") %></div>
</p>
<p>
Price: <%= Html.TextBox("Price") %>
<div><%= Html.Validationmessage("Price") %></div>
</p>
<p>
Category: <%= Html.TextBox("Category") %>
<div><%= Html.Validationmessage("Category") %></div>
</p>
<p>
Image:
<% if(Model.ImageData == null) { %>
None
<% } else { %>
<img src="<%= Url.Action("GetImage","Products",new { Model.ProductID }) %>" />
<% } %>
<div>Upload new image: <input type="file" name="Image" /></div>
</p>
<input type="submit" value="Save" />
<%=Html.ActionLink("Cancel and return to List","Index") %>
<% } %>
</asp:Content>
控制器
[AcceptVerbs(httpVerbs.Post)] public ActionResult Edit(Product product,httpPostedFileBase imagE) { if (ModelState.IsValid) { if (image != null) { product.ImageMimeType = image.ContentType; product.ImageData = new byte[image.ContentLength]; image.InputStream.Read(product.ImageData,image.ContentLength); } productsRepository.SaveProduct(product); TemPDAta["message"] = product.Name + " has been saved."; return RedirectToAction("Index"); } else // Validation error,so redisplay same view return View(product); }
