c# - Return object only if object could be properly created -


I am very new to C # programming and I am struggling with OOP a little bit.

I have created a class with the method that analyzes a text file and creates an object based on its content. I want this function to return an object, which contains some information from the text file, only if the text file is in the correct format.

I call the function to analyze the text file like this: 

  PokerHand newhand; NewHand = new poker hand (); AnalyzePokerHand.importHand ("C: \\ text.txt"); NewHand = Analysis PokerHand.getAnalyzedHand;   
 If text.txt is not a poker hand history file, or wrong format etc, then I do not want to fill it with  newHand  Information of  
 What happens correctly if I want to pass the path to a text file and only return the object with information about the hand only if the function is successful?  
 Take a look!   
 
 
 If you want to indicate that no data is available, then returning the tap is best The way. The second advantage of this approach is that if you try to use member variables, then this zero indicator will throw exceptions.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
