为什么访问路径被拒绝？ [英] Why is access to the path denied?

问题描述

我有哪里我想删除我的文件有问题，但我得到一个异常。

I am having a problem where I am trying to delete my file but I get an exception.

if (result == "Success")
{
     if (FileUpload.HasFile)
     {
         try
         {
              File.Delete(Request.PhysicalApplicationPath + app_settings.login_images + txtUploadStatus.Text);
              string filename = Path.GetFileName(btnFileUpload.FileName);
              btnFileUpload.SaveAs(Request.PhysicalApplicationPath + app_settings.login_images + filename);
         }
         catch (Exception ex)
         {
               Message(ex.ToString());
         }
      }
}

另外我要指出，我试图从删除的文件夹具有完全控制的网络服务。

Also I should note that the folder I am trying to delete from has full control to network services.

完整的异常消息是：

System.UnauthorizedAccessException：对路径C：\\用户\\ gowdyn \\文档\\ Visual Studio 2008的\\项目\\混合\\混合\\ temp_loginimages \\ enviromental.jpg'被拒绝。在System.IO .__ Error.WinIOError（的Int32错误code，字符串maybeFullPath）在System.IO.File.Delete（字符串路径）在hybrid.User_Controls.Imgloader_Add_Edit_Tbl.btnUpdate_Click（对象发件人，EventArgs e）在C：\\用户\\ gowdyn \\文档\\ Visual Studio 2008的\\项目\\混合\\混合\\ User_Controls \\ Imgloader_Add_Edit_Tbl.ascx.cs：行242

任何想法？

推荐答案

我也有这个问题，所以我磕磕绊绊对这个职位。我加code以下前行和复制/删除。

I also had the problem, hence me stumbling on this post. I added the following line of code before and after a Copy / Delete.

删除

File.SetAttributes(file, FileAttributes.Normal);
File.Delete(file);

复制

File.Copy(file, dest, true);
File.SetAttributes(dest, FileAttributes.Normal);
