specific file, read and write permissions are not required.Vi. functions Access and FaccessatWhen a file is opened with the open function, the kernel performs a test of its access based on the process's valid user ID and valid group ID. Sometimes processes also want to test their access capabilities by their actual user ID and actual group ID, and access and Faccessat are designed to do this, regardless of the valid user ID and valid group ID, which are tested with the actual user ID and the ac
Use vs2015 to open the old project, previously using IIS to configure the site, and then attach w3wp.exe in VS to develop and debug.There are various failures in configuring sites on IIS for various reasons.It was later found that it would be more convenient to press F5 in vs2015, but the old project used a virtual directory.

Configuration conf = new Configuration();
