Question

我正在ASP.NET Framework中开发网站，其中有一个页面，用户需要上传文件以进行注册，它应该是pdf格式，但是当我点击提交按钮时，我会收到错误页面。

尝试使用这样的代码（我不知道你的代码）：

ASPX：

<input id="up" runat="server" type="file" />

代码背后：

up.PostedFile.SaveAs(HttpContext.Current.Server.MapPath("/")+"yourFolder\\"+up.PostedFile.FileName);

以及Darin Dimitrov说，请确保您的文件夹存在。

当时从我的网站上传文件我收到此错误
