title: 2sxc Linq query for Categories
body: <p>I have entities: Documents, Category, DocList</p>
  
  <p>Documents and DocumentList can have multiple categories selected.</p>
  
  <p>I want to make filter for Documents that are in one or more categories.</p>
  
  <pre><code>// all documents
  var items = AsDynamic(App.Query["DocList"]["AllDocs"]);
  // categories for filter
  var fcat = Content.Category;
  
  //linq query??
  items = items.Where(d=&gt;d.Category ....????....);
  </code></pre>
  
  <p>Can and how I can make this kind of filter?</p>
  
  <p>Content.Category is list of Categories.</p>
  
  <p>So I want to show list of items if there are in any of categories, not only one</p>
  
  <p>something like this: <a href="https://stackoverflow.com/questions/10667675/linq-where-list-contains-any-in-list">linq where list contains any in list</a></p>
