我有一个问题,我试图删除我的文件,但我得到一个例外.

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());
         }
      }
}

另外我应该注意,我尝试删除的文件夹可以完全控制网络服务.

完整的异常消息是:

System.UnauthorizedAccessException:拒绝访问路径'C:\ Users\gowdyn\Documents\Visual Studio 2008\Projects\hybrid\hybrid\temp_loginimages\enviromental.jpg'.at System.IO .__ Error.WinIOError(Int32 errorCode,String maybeFullPath)at System.IO.File.Delete(String path)at hybrid.User_Controls.Imgloader_Add_Edit_Tbl.btnUpdate_Click(Object sender,EventArgs e)in C:\ Users\gowdyn\Documents\Visual Studio 2008\Projects\hybrid\hybrid\User_Controls\Imgloader_Add_Edit_Tbl.ascx.cs:第242行

有任何想法吗？
