Is it okay to call OracleConnection.Open() if the connection is already open?

Question

IOW, is there a standard way of testing for this, a la:

if (! con.Open())
  con.Open();

?

UPDATE: I guess I failed to mention that these are Oracle's ODP components I'm using. The OracleConnection component does not have a ConnectionState property.

Answer 1

Use the Connection.State property to check whether the connection is already open

if(con.State == ConnectionState.Closed){
  con.Open();
}

Answer 2

if(Con.State != ConnectionState.Open)
con.Open(); 

if you want open only closed connections you can use

if(Con.State == ConnectionState.Close)
con.Open();
