title: how to use .Contains LINQ in decimal fields
body: <p>I need to filter by a field of type decimal. How Do I?</p>
  
  <p>Here's how I do for string fields:</p>
  
  <pre><code>cartaoCredito.strCartaoCreditoDescricao.ToUpper().Contains(strParam.ToUpper())
  </code></pre>
  
  <p>Here is my method:</p>
  
  <pre><code>public List&lt;CartaoCredito&gt; GetCartaoCreditoByintCodigoGrupoUsuarioByFiltro(int intCodigoGrupoUsuario, string strParam)
      {
          return (from cartaoCredito in _DatabaseContext.CartaoCredito
                  where cartaoCredito.intCodigoGrupoUsuario == intCodigoGrupoUsuario &amp;&amp; (cartaoCredito.strCartaoCreditoDescricao.ToUpper().Contains(strParam.ToUpper()))
                  select cartaoCredito).ToList();
      }
  </code></pre>
