  - by fire

  I have an input field whose name is an MD5 string e.g.: <input type="hidden" name="7815696ecbf1c96e6894b779456d330e" value="1"> Now I understand that having a number as the first letter in an input field name is generally bad practice, but are there any side-effects to this such as a certain browser won't send it in the POST request?

• C# (non-abstract) class to represent paths

  - by user289770

  I'm looking for a C# class that represents a file system path. I would like to use it (instead of strings) as the data type of variables and method arguments (top reasons: type safety, concat-proof, logical comparisons). System.IO.Path provides most of the functionality I want, but it is abstract. System.IO.FileInfo, as I understand, performs IO operations to do its job. I only want a wrapper for the path string. Thanks!
