SSIS : Accessing Variables

During some recent SSIS package development I had cause to access a variable I had defined from scripts in both the Control and Data flows.

So that I remember (and for anyone else that cares) here is the subtle difference in syntax.
(I'm using SSIS 2008)

For the Script Task (within the Control flow) >

1) Add your defined variable to the ReadWriteVariables property of the task.
2) Within the script, refer to the variable like this :

Dts.Variables("User::MyVariable").Value = “New Value”


Within a Script Component (inside a Data flow) >

1) Add the variable to the ReadWriteVariables property of the component.
2) Within the script, refer to the variable like this :

Me.ReadWriteVariables("User::MyVariable").Value = “New Value”
