c# - LINQ Getting Unique items from a List within a List -


मेरे पास एक परिभाषा के साथ सूची प्रकार MyObject है: <पूर्व> वर्ग MyObject {सार्वजनिक स्ट्रिंग ListName {get; सेट; } सार्वजनिक IEnumerable & lt; अन्य ऑब्जेक्ट & gt; वस्तुसूची {प्राप्त करें; LINQ का उपयोग करके सूची प्रकार MyObject को देखते हुए सभी विशिष्ट प्राप्त करने के लिए मुझे किस अभिव्यक्ति का उपयोग करना चाहिए? OtherObject ?

मैं जो करने की योजना बना रहा था वह प्रत्येक MyObject लूप था और अन्य ऑब्जेक्ट को ObjectList संपत्ति से प्राप्त किया गया था, लेकिन तब मुझे सूची में विशिष्ट होना चाहिए।

कृपया ध्यान दें कि यदि: MyObject [0]। ओब्जेस्टलिस्ट [0] == 'मद' ए ' और MyObject [1 ] .ऑब्जेक्टसूची [0] == 'मद' ए ' यह अभी भी ItemA का एक उदाहरण वापस करेगा। यह कोड केवल एक प्रतिनिधित्व है ऐसा नहीं है कि मैं अपने ऑब्जेक्ट्स को किस तरह से एक्सेस कर सकता हूं।

आप यह केवल तर्क का उपयोग करके प्राप्त कर सकते हैं। सी # के रूप में एक अच्छा कार्यान्वयन है: 

  var set = new HashSet & lt; अन्य ऑब्जेक्ट & gt; (myObjects.SelectMany (मो = & gt; मो। ऑब्जेक्ट लिस्ट));   
 या यदि आप आस्थगित निष्पादन को पसंद करते हैं, तो आप LINQ विधि का उपयोग कर सकते हैं:  
  var अलग = myObjects.SelectMany (मो = & gt; मो। ऑब्जेक्टसूची) .Distinct ();

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

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...
