Asp.Net MVC3 上传文件问题

在MVC3中，我用HttpPostedFileBase作为上传文件的参数类型，但是在SavaAs方法中却提示不支持给定路径的格式，求解决方法
所写代码如下

Answer 1

可以考虑一下以下代码：首先创建：一 创建表单
@using (Html.BeginForm("Index", "Home", FormMethod.Post, new { enctype = "multipart/form-data" })){ <input type="file" name="file" /> <input type="submit" value="OK" />}
二 创建controlle

public class HomeController : Controller{ // This action renders the form public ActionResult Index() { return View(); } // This action handles the form POST and the upload [HttpPost] public ActionResult Index(HttpPostedFileBase file) { // Verify that the user selected a file if (file != null && file.ContentLength > 0) { // extract only the fielname var fileName = Path.GetFileName(file.FileName); // store the file inside ~/App_Data/uploads folder var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName); file.SaveAs(path); } // redirect back to the index action to show the form once again return RedirectToAction("Index"); }}
