Check if SQL Connection is Open or Closed

Question

How do you check if it is open or closed I was using

 if (SQLOperator.SQLCONNECTION.State.Equals(\"Open\"))

however, even the State is \'Op

Answer 1

Here is what I'm using:

if (mySQLConnection.State != ConnectionState.Open)
{
    mySQLConnection.Close();
    mySQLConnection.Open();
}

The reason I'm not simply using:

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

Is because the ConnectionState can also be:

Broken, Connnecting, Executing, Fetching

In addition to

Open, Closed

Additionally Microsoft states that Closing, and then Re-opening the connection "will refresh the value of State." See here http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.state(v=vs.110).aspx
