OracleConnection: what are Clearpool, Dispose and Close?

Question

I would like to understand what does Clearpool , Dispose , Close do in OracleConnection?

After exception occurs, I would like to get rid off the current connection and create a total new connection with the same connection string. How should I get rid off the old connection?

Should l clearpool firstly or dispose the connection? And what does clearpool vs dispose/close do?

My current code is like below:

public virtual void Dispose()
  {
     try
      {
         _connection.Close();

      }
      catch (Exception e)
      {
      }
      finally
      {
          _connection.Dispose();
          _connection.ClearPool();
          _connection = null;
      }            
  }

Answer 1

The easiest way to solve this is to create the connection inside a using block. Everything inside that block will be disposed whenever the block execution finishes. Also, do NOT leave a catch with no action inside. This might end on a silent exception that you will be not aware of.

using(OracleConnection conn = new OracleConnection("yourConnStr"))
{
    //ALL YOUR LOGIC INSIDE
}
