title: Remove columns from list object out of a class c#
body: <p>I need the possiblity to create Code in C# like this</p>
  
  <pre><code>public class SummaryA 
  {
      public string name { get; set; }
      public string surename { get: set; }
      public int age { get; set;}
  }
  </code></pre>
  
  <p>now I create an list object from the class SummaryA</p>
  
  <pre><code>List&lt;SummaryA&gt; list1= new List&lt;SummaryA&gt;(); 
  </code></pre>
  
  <p>yet I need the possibility to remove the column age from the list Summary, anyone have ideas?
  I need this for some more columns, so I wish the list was dynamically or some things else.</p>
  
  <p>sry for my bad english.</p>
