.net - skipping over potential nulls c# -

-

I have a block of code that eventually ends up with J.K. The full calender plugin has been serialized for use in JSN. The ToUnixTimeSpan method works in a DateTime object and returns the number of seconds from 1970

The date-column may be blank in this section of the code how I'll test for the null and leave the end = toUnixTimespan (e.DateEnd) if the date is blank? Is groovy equal operator of c #?

list var listEvents = from eventRepository.GetAllEvents () new {id = e.EventID, title = e.EventTitle, start = toUnixTimespan (E.Dart Start), and = Tunics Timesman (edited), url = "/ events / description /" + e. AVEEND}; Further information about ToUnixTimespanMethod: 

  Private toUnixTimespan {datepace tspan = date.ToUniversalTime (). Subtract (New DateTime (1970), 1, 1, 0, 0, 0)); Return (Long) Mathematics. Reposition (tspan numeric); } 
 
 
 Wait - one minute ... why am I commenting on this, When I can take advantage of John's work for some representative ..;)  
  end = e.DateEnd == null? (Long?) Tap: ToUnixTimespan (e.DateEnd.Value)  
 
 It should resolve "system. Can not be changed from datetime?" For 'System.DateTime' "Error.

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
