MVC3 上传文件-白红宇

注意：红色部分必须添加

前台：

ViewBag.Title = AutoUpdater.Profile.title + " - 上传升级文件";

}

@model AutoUpdater.Models.UploadFileModel

<h2>上传升级文件</h2>

@Html.ValidationSummary(true)

<div class="validation-summary-errors">@ViewBag.ErrorMessage</div><br />

@using (Html.BeginForm("UploadFile", "Operations", FormMethod.Post,

new { enctype = "multipart/form-data" }))

{

<div>

<legend>升级文件信息</legend>

@Html.LabelFor(m => m.Version)

</div>

@Html.TextBoxFor(m => m.Version)

@Html.ValidationMessageFor(m => m.Version)

</div>

@Html.LabelFor(m => m.UFile)

</div>

</div>

<p>

</p>

</fieldset>

</div>

}

后天：

[AcceptVerbs(HttpVerbs.Post)]

public ActionResult UploadFile(FormCollection collection, UploadFileModel model)

{

if (Session["UserID"] == null)

{

ViewBag.ErrorMessage = "请先登录！";

return View();

}

if (Request.Files.Count == 0)

{

ViewBag.ErrorMessage = "请选择上传的升级文件！";

return View();

}

var fileVersion = Request.Files[0];

if (fileVersion == null || (fileVersion != null && fileVersion.ContentLength == 0))

{

ViewBag.ErrorMessage = "请选择上传的升级文件！";

return View();

}

if (fileVersion != null && fileVersion.ContentLength > 0)

{

if (fileVersion.ContentLength < Profile.minLen || fileVersion.ContentLength > Profile.maxLen)

{

ViewBag.ErrorMessage = string.Format("上传的升级文件必须介于{0}K-{1}K之间！", Profile.minLen / 1024, Profile.maxLen / 1024);

return View();

}

using (var db = new LogDB(Profile.dbpath))

{

if (db.ExistVersion(model.Version.ToUpper()))

{

ViewBag.ErrorMessage = "已经存在相同版本号的升级文件！";

return View();

}

string suffix = Path.GetExtension(fileVersion.FileName).ToLower();

string fileName = string.Format("{0}{1}", model.Version.ToUpper(), suffix);

fileVersion.SaveAs(Path.Combine(Profile.filepath, fileName));

using (var db = new LogDB(Profile.dbpath))

{

db.Write(fileName, Session["UserID"].ToString(), fileVersion.ContentLength, model.Version.ToUpper());

}

return RedirectToAction("FileList", "Operations");

}

return View();

}
