* either the list contained in the ReadOnlyVariables property or the list contained in
* the ReadWriteVariables property of this script task, according to whether or not your
* code needs to write to the variable. To add the variable, 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:
* DateTime startTime = (DateTime) Dts.Variables["System::StartTime"].Value;
*
* Example of writing to a variable:
* Dts.Variables["User::myStringVariable"].Value = "new value";
*
* Example of reading from a package parameter:
* int batchId = (int) Dts.Variables["$Package::batchId"].Value;
*
* Example of reading from a project parameter:
* int batchId = (int) Dts.Variables["$Project::batchId"].Value;
