title: Bool type return rule
body: <p>I use dapper ORM.So i use two rules <code>Query&lt;T&gt;</code> &amp; <code>QuerySingle&lt;T&gt;</code>. Query return the list &amp; QuerySingle return the single object.</p>
  
  <p>So,I want to get a bool type. (Actually I wanted to get a bool is true or false record).</p>
  
  <p>My <code>Query&lt;T&gt;</code>:</p>
  
  <pre><code>public IEnumerable&lt;T&gt; Query&lt;T&gt;(string SqlString) where T : class
  {
      return this.conn.Query&lt;T&gt;(SqlString);
  }
  </code></pre>
  
  <p>So how can I write bool type return?</p>
