在asp.net mvc中上傳大檔案

標籤：

在asp.net mvc 頁面裡上傳大檔案到伺服器端，需要如下步驟：

1. 在Control類裡添加get 和 post 方法

 1         // get method 2         public ActionResult Upload() 3         { 4             return View(); 5         } 6  7         // This action handles the form POST and the upload 8         [HttpPost] 9         public ActionResult Upload(HttpPostedFileBase file)10         {11             // Verify that the user selected a file12             if (file != null && file.ContentLength > 0)13             {14                 // extract only the fielname15                 var fileName = Path.GetFileName(file.FileName);16                 // store the file inside ~/App_Data/uploads folder17                 var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);18                 file.SaveAs(path);19             }20             // redirect back to the index action to show the form once again21             return RedirectToAction("Upload");22         }

2. 建立view頁面，並且添加如下代碼：

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

3. 在Web.config裡做如下添加和修改：

在<system.web>裡添加

<httpRuntime targetFramework="4.5" maxRequestLength="1048576" executionTimeout="3600"/>

並且在<system.webServer>裡添加

    <security>      <requestFiltering>        <requestLimits maxAllowedContentLength="1073741824" />      </requestFiltering>    </security>

大功告成！
