title: Can't access the class I just created
body: <p>I hope this is a simple question. I'm building a simple console application in C#.  I have a class:</p>
  
  <pre><code>using System;
  using Filter;
  
  public class Params
  {
      public string key;
      public bool distinct;
      public List&lt;string&gt; fields;
      public string filter;
      public int limit;
      public int skip;
      public bool total;
      public List&lt;Tuple&lt;string, GroupType&gt;&gt; group;
      public List&lt;Tuple&lt;string, OrderType&gt;&gt; order;
  
      public Params()
      {
          key = "";
          distinct = false;
          fields = new List&lt;string&gt;();
          filter = "";
          group = new List&lt;Tuple&lt;string, GroupType&gt;&gt;();
          limit = 0;
          order = new List&lt;Tuple&lt;string, OrderType&gt;&gt;();
          skip = 0;
          total = false;
      }
  
      public void AddGroup(string field, GroupType type)
      {
          group.Add(new Tuple&lt;string, GroupType&gt;(field, type));
      }
  
      public void AddOrder(string field, OrderType type)
      {
          order.Add(new Tuple&lt;string, OrderType&gt;(field, type));
      }
  }
  </code></pre>
  
  <p>My program .cs class is:</p>
  
  <pre><code>namespace csharpExample
  {
      class Program
      {
          public static void Main(string[] args)
          {
              Params p = new Params();
              Console.WriteLine("Test");
          }
      }
  }
  </code></pre>
  
  <p>I want to use Params in my program.cs class where Main() is called.  I thought I could simply use Params like above. I've also tried to do a using Params; both of these are errors in VS since it can't find the directive. I've also tried adding my own namespace: namespace MyNameSpace; around my Params class. When I do this I still am unable to do a using MyNameSpace; statement as it can't find it.</p>
  
  <p>I just want to extract out a bunch of functions into a class that I can reuse. How do i call this class once it's created?</p>
  
  <p>-Thanks
  Thanks for the help.</p>
