我收到此错误无法找到文件'C：\program files（x86）\ IIS express\uploadfile'。 [英] I am getting this error could not find file 'C:\program files (x86)\IIS express\uploadfile'.

问题描述

 var oldFileTxt = Server.MapPath（@txtp1.Text）; 
 var newFileTxt = Server.MapPath（@txtp2.Text）;我已经使用了这段代码并在阅读文件路径时收到错误。

我尝试了什么：



而不是server.path我使用过File.Readline但得到了同样的错误。我希望这是动态的。请建议

解决方案

假设文件位于您网站的根目录中 - 这是一个不好的主意 - 您需要在文件名前加上〜 - 如果不这样做，则假定它在与页面ASPX文件相同的文件夹：

 string oldFileTxt = Server.MapPath（@〜/ txtp1.Text）; 

更好的主意是专门为文件创建一个文件夹并使用它：

 string oldFileTxt = Server.MapPath（@〜/ Uploads / txtp1.Text）; 

var oldFileTxt = Server.MapPath(@"txtp1.Text");
var newFileTxt = Server.MapPath(@"txtp2.Text"); i have used this code and getting error while reading the path of the file.

What I have tried:

instead of server.path i have used File.Readline but getting the same error .i want this to be dynamic .please suggest

解决方案

Assuming the file is in the root directory of your website - which is a poor idea - you need to prefix the filename with a "~" - if you don't it's assumed to be in the same folder as the page ASPX file:

string oldFileTxt = Server.MapPath(@"~/txtp1.Text");

A better idea is to create a folder specifically for files and use that:

string oldFileTxt = Server.MapPath(@"~/Uploads/txtp1.Text");
