linq - EntitySet<IEnumerable<T>> to IEnumerable<T> -

-

मेरे पास 

  EntitySet & lt; IEnumerable & lt; T & gt; & gt;

कुछ क्वेरी से लौटकर उसे 

  IEnumerable & lt; T & gt; पर डालने की आवश्यकता है।

क्या मैं यह कर सकता हूं?

एंटिटीसेट & lt; IEnumerable & lt; T & gt; लागू करता है IEnumerable & lt; IEnumerable & lt; T & gt; & gt; तो आप यह कर सकते हैं: 

  IEnumerable & lt; T & gt; चपटा हुआ सूची = इकाईसैट। चयन करेंमौनी (ई = & gt; ई);

थोड़ा अजीब लगता है, लेकिन SelectMany एक फ़ंक्शन लेता है जो सूची में प्रत्येक आइटम से "बाल सूची" प्राप्त करता है और फिर सभी बाल सूचियों को एक साथ जोड़ती है एक एकल सूची इस मामले में, सूची में प्रत्येक आइटम एक सूची है, इसलिए लैम्ब्डा अच्छा और छोटा है।

delphi - Mouseover hint for TChart series value -

Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

c++ - Linux and clipboard -

-
After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

How to Create Master-Details view using Asp.Net MVC framework -

-
I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...
