System.UnauthorizedAccessException: 对 path:PATH 的访问被拒绝

Question

由于某种原因，Windows拒绝我的Web客户端下载。

它有权执行所有操作，但仍被拒绝。为什么？

法典：

web.DownloadFile("super epic link", location);

错误：

System.Net.WebException: An exception occurred during a WebClient request. ---> System.UnauthorizedAccessException: Access to the path 'C:UsersJANGAJ GAMESsourcereposhtml executerhtml updaterbinDebug' is denied.

Answer 1

这是因为IIS无法访问该文件。请改用Path.GetDirectoryName(Application.ExecutablePath)访问应用的当前文件夹

var fileName = Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), "download.txt");
web.DownloadFile("super epic link", fileName);
