删除服务器上的文件 [英] Delete file on server

问题描述

我有一个文件路径，格式为 file：//SERVERNAME/FOLDER$/FOLDER/image.jpg 。我调用 System.IO.File.Delete（Server.MapPath（file：//SERVERNAME/FOLDER$/FOLDER/image.jpg））删除文件，但是我出现错误 file：/SERVERNAME/FOLDER$/FOLDER/image.jpg'不是有效的虚拟路径。我注意到缺少'/'，但我没有知道为什么。我将如何删除此类文件？

I have a file path in the format file://SERVERNAME/FOLDER$/FOLDER/image.jpg. I call System.IO.File.Delete(Server.MapPath(file://SERVERNAME/FOLDER$/FOLDER/image.jpg)) to delete the file, but i get the error file:/SERVERNAME/FOLDER$/FOLDER/image.jpg' is not a valid virtual path. I notice that a '/' is missing and I do not know why. How will I delete such file?

我尝试将文件路径转换为 file：//// SERVERNAME // FOLDER $ // FOLDER //image.jpg ，但这没有帮助。同样的事情发生。如果我省略 Server.MapPath ，则会收到一条错误消息，指出不支持URI。

I have tried converting my file path to file:////SERVERNAME//FOLDER$//FOLDER//image.jpg but this did not help. Same thing happens. If I omit the Server.MapPath, I get an error saying URI is not supported.

操作方法

推荐答案

因为您正在执行 System.IO.File.Delete 我假设您有权删除该文件；因此您可以：

Since you are doing System.IO.File.Delete I assume you have the permission to delete the file; so you can:

var uri = new Uri("file://SERVERNAME/FOLDER$/FOLDER/image.jpg", UriKind.Absolute);
System.IO.File.Delete(uri.LocalPath);
