title: Throwing a custom exception inside try catch
body: <p>If I have some code inside a big try catch which eventually catches an <code>OracleException</code> and a general <code>Exception</code> then I can't throw any custom exception inside the try catch can I, as it gets caught by the general <code>Exception</code>.</p>
  
  <p>What am I supposed to do in this instance?</p>
  
  <p>Thanks</p>
  
  <pre><code>try
  {
      // some code
      if(a==b)
      {
          throw new MyCustomException(ex);
      }
  }
  catch(OracleException ex)
  {
      ...
  }
  catch(Exception ex)
  {
      ...
  }
  </code></pre>
