在ASP.NET MVC中上传图像

Question

我有一个上传表单,我想传递我的信息,如图像和其他一些领域,但我不知道如何上传图像..

这是我的控制器代码:

[HttpPost]
        public ActionResult Create(tblPortfolio tblportfolio)
        {
            if (ModelState.IsValid)
            {
                db.tblPortfolios.AddObject(tblportfolio);
                db.SaveChanges();
                return RedirectToAction("Index");  
            }

            return View(tblportfolio);
        }

这是我的查看代码:

@model MyApp.Models.tblPortfolio

<h2>Create</h2>

@using (Html.BeginForm(null, null, FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>tblPortfolio</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.Title)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Title)
            @Html.ValidationMessageFor(model => model.Title)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.ImageFile)
        </div>
        <div class="editor-field">
            @Html.TextBoxFor(model => model.ImageFile, new { type = "file" })
            @Html.ValidationMessageFor(model => model.ImageFile)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Link)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Link)
            @Html.ValidationMessageFor(model => model.Link)
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

现在我不知道如何上传图像并将其保存在服务器上..如何设置图像名称Guid.NewGuid();？或者我该如何设置图像路径？

首先,您需要更改视图以包含以下内容:

<input type="file" name="file" />

然后,你需要改变你的职位ActionMethod采取了HttpPostedFileBase,就像这样:

[HttpPost]
public ActionResult Create(tblPortfolio tblportfolio, HttpPostedFileBase file)
{
    //you can put your existing save code here
    if (file != null && file.ContentLength > 0) 
    {
        //do whatever you want with the file
    }
}
