c# - Selecting columns from a LINQ query -

-

I want to be able to select the columns displayed in my datagrid view. I.e., I have a linq query that gives an IEnumerable, but I do not want to display all the properties of the policy - I want to allow the user to show what to display. So I thought that something like this could work to create a "narrow" object with only columns. 

  IEnumerable & lt; Policy & gt; Policies = Repository Gate policies (); P = Out of the policies = Negatives = Select new (if user ("propertyon") ()) propertyon = p. Property On, if (userpic ("property two")) PropertyTwo = p.PropertyTwo, ...}; DataGridView1.DataSource = Results;

Is there a great way to do this?

Part 2: Why does this work: 

  IEnumerable & lt; Policy & gt; Policies = Repository Gate policies (); DataGridView1.DataSource = Policies;

But it is not: 

  IEnumerable

In the second case nothing is displayed in the grid.

If you need to select the field dynamically, use it in a selection is an extension method that accepts a string of fields, so that you can decide which fields to select at runtime: 

  select the public static IQueryable (this IQueryable source , String selector, parameters object [] value);

Example of use: 

  var products = db.Products. Where (status). Orderbird ("name"). Select ("new ID (ID id, name, model, onsale)");

Part 2: Your grid is expecting a bindable interface such as IList , but the second code gives the example IQueryable is. You can call it iliast to toList () . 

  var can change by result = (Select P from the policies p). List ();

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

php - Laravel - Overriding a resource route into a different route filter group -

-
Does Laravel's routing work as expected? What I think, if I want to override a route, then I just have to give the expected route before each other. I have something like this: root :: group (array ('first' = & gt; 'defaultLoads' =); function () {root :: post 'Newsletter', 'newsletter controller @ store'); root: group (array ('(newsletter', 'newsletter controller');}}); That if I post this route, only http://domain.com/newsletter should run only the default loads route filter. However, when I call php Runs artisan routes , I get this: | | POST newsletter | newsletter.store | newslettercontroller@ store | default loads | login | | though it reads the route correctly (PHP artisan loads which The correct path is to the right place) but the file of the resource path even if it is not in the filter group, the path is affected. Then my question: How does it work Laravel? If so, do I post this -> Newsle...
