如何为mvc3文件上传编码控制器

标签: c# asp.net asp.net-mvc-3 razor

@model Framely2011.Models.PictureUpload

@{
    ViewBag.Title = "Upload";
}

<h2>Upload</h2>

@using (Html.BeginForm("Upload", "Member", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <input type="file" name="myFile" id="myFile" />

    @Html.TextBoxFor(x => x.MetaTagsObj.Meta1)<br />
    @Html.TextBoxFor(x => x.MetaTagsObj.Meta2)<br />
    @Html.TextBoxFor(x => x.MetaTagsObj.Meta3)<br />

    <input type="submit" value="submit" />
}

这是我到目前为止,这是我的模型的样子:

public class PictureUpload
    {
        public HttpPostedFile fileName { get; set; }
        public MetaTags MetaTagsObj { get; set; }
    }

我不确定如何编写我的控制器以进行图片上传或如何在我执行[HttpPost]

时在控制器上传文件

以下是我过去的做法(asp.net mvc 2)...使用.net 4和asp.net mvc 3可能更容易实现它。

foreach (string upload in Request.Files)
            {
                if (!Request.Files[upload].HasFile()) continue;

                string mimeType = Request.Files[upload].ContentType;
                Stream fileStream = Request.Files[upload].InputStream;
                string fileName = Path.GetFileName(Request.Files[upload].FileName);
                int fileLength = Request.Files[upload].ContentLength;
                byte[] fileData = new byte[fileLength];
                fileStream.Read(fileData, 0, fileLength);
                //do something with the byte array (filedata)
            }

HasFile()是一个定义如下的扩展方法:

public static class HttpPostedFileBaseExtensions
{
    public static bool HasFile(this HttpPostedFileBase file)
    {
        return (file != null && file.ContentLength > 0);
    }
}

您可以将模型作为[HttpPost]操作方法中的参数,并阅读fileName属性。
