这是我使用ASP.NET MVC 3和Microsoft.Web.Helpers NuGet插件的图像上传解决方案.

现在的viewmodel代码

namespace MvcImageUpload.Models {
    public class ImageUploadviewmodel {
        [UIHint("UploadedImage")]
        public string ImageUrl { get; set; }
        public string ImageAltText { get; set; }
    }    
}

现在对于控制器,我简单地把它放到了家庭控制器中,因为这只是一个模拟项目来使它工作.我刚刚添加了一个ActionResult,它将ImageUploadviewmodel作为参数.

public ActionResult Upload(ImageUploadviewmodel model) {
        var image = WebImage.GetImageFromRequest();

        if (image != null) {
            if (image.Width > 500) {
                image.Resize(500,((500 * image.Height) / image.Width));
            }

            var filename = Path.GetFileName(image.FileName);
            image.Save(Path.Combine("../Uploads/Images",filename));
            filename = Path.Combine("~/Uploads/Images",filename);

                model.ImageUrl = Url.Content(filename);
                model.ImageAltText = image.FileName.Substring(0,image.FileName.Length - 4);

        }

        return View("Index",model);
    }

我对于上传图像的看法很简单,它有一个Html.BeginForm,它处理Post Form方法,并且将编码类型设置为“multipart / form-data”.

然后使用Microsoft.Web.Helpers.FileUpload帮助器,我从HTTP发布请求一个图像,然后使用名为ImageViewer的自定义DisplayFor模板显示它.

@model MvcImageUpload.Models.ImageUploadviewmodel
    @using Microsoft.Web.Helpers;
    @{
        ViewBag.Title = "Index";
     }

    <h2>Image Uploader</h2>
    @using (Html.BeginForm("Upload","Home",FormMethod.Post,new { @encType = "multipart/form-data" })) {           
        @FileUpload.GetHtml(initialNumberOfFiles: 1,allowMoreFilesToBeAdded: false,includeFormTag: false,addText: "Add Files",uploadText: "Upload File") <br />        

        <input type="submit" name="submit" 
               value="Upload Image" text="Upload Images" 
               style="font-size: .9em;" />
        @Html.DisplayFor(x => x,"ImageViewer")<br />
    }

这是自定义DisplayTemplate的外观

@model MvcImageUpload.Models.ImageUploadviewmodel
@if (Model != null) { 
    <h4 style="color:Green;">Upload Success!</h4>           
    <p>
        Alt Text has been set to <strong>@Model.ImageAltText</strong>
    </p>
    <img  style="padding: 20px;" 
        src="@(String.IsNullOrEmpty(Model.ImageUrl) ? "" : Model.ImageUrl)" 
            id="uploadedImage"  alt="@Model.ImageAltText"/>
}

这一切工作,图像成功上传到表单上的/Uploads/Images/FileName.extension.

我的问题

我现在可以有另一个视图显示该目录中的所有图像,分页并能够从视图和目录中选择和删除和映像？

另外我知道Microsoft.Web.Helpers.FileUpload,支持上传多个文件,但是我找不到如何用我目前的解决方案来实现.任何帮助都会被大大的赞赏.
