* either the list contained in the ReadOnlyVariables property or the list contained in
* the ReadWriteVariables property of this script component, according to whether or not your
* code needs to write into the variable. To do so, save this script, close this instance of
* Visual Studio, and update the ReadOnlyVariables and ReadWriteVariables properties in the
* Script Transformation Editor window.
* To use a parameter in this script, follow the same steps. Parameters are always read-only.
*
* Example of reading from a variable or parameter:
* DateTime startTime = Variables.MyStartTime;
*
* Example of writing to a variable:
* Variables.myStringVariable = "new value";

#region Help: Using Integration Services Connnection Managers
/* Some types of connection managers can be used in this script component. See the help topic
* "Working with Connection Managers Programatically" for details.
*
* To use a connection manager in this script, first ensure that the connection manager has
* been added to either the list of connection managers on the Connection Managers page of the
* script component editor. To add the connection manager, save this script, close this instance of
* Visual Studio, and add the Connection Manager to the list.
*
* If the component needs to hold a connection open while processing rows, override the
* AcquireConnections and ReleaseConnections methods.
*
* Example of using an ADO.Net connection manager to acquire a SqlConnection:
* object rawConnection = Connections.SalesDB.AcquireConnection(transaction);
* SqlConnection salesDBConn = (SqlConnection)rawConnection;
*
* Example of using a File connection manager to acquire a file path:
* object rawConnection = Connections.Prices_zip.AcquireConnection(transaction);
* string filePath = (string)rawConnection;
*
* Example of releasing a connection manager:
* Connections.SalesDB.ReleaseConnection(rawConnection);
