SSIS Task Script Dts.Variable Error

Hello everyone,

This is my first post. :-)

I've been having an error with Script Tasks in SSIS, where the error is every time I use a For Each In Dts.Variables, it always seems to crash. I'm trying to log the variables before I proceed in any other tasks. I'm passing in one value as a ReadOnlyVariables.

Here is the snippet of code:

Dts.Log(String.Format("{0} variables:", Dts.Variables.Count), 0, Nothing)
For Each v As Variable In Dts.Variables
Dts.Log(String.Format("{0} = {1}", v.Name, v.Value), 0, Nothing)
Next

It's very strange because the Dts.Variables.Count gives me the correct number of items that I have passed in, but after I step into the For Each, I get this for Dts.Variables.Item:

In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user. Microsoft.SqlServer.Dts.Runtime.Variable

And as soon as I step into the next line, it crashes with this error:

Value does not fall within the expected range.
at Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSVariables90.GetEnumerator()
at Microsoft.SqlServer.Dts.Runtime.Variables.GetEnumerator()
at ScriptTask_932938a13af547149ade0331cf39ecfe.ScriptMain.Main()


My colleagues have tried this snippet of code and it worked fine on their machine, only mine has this error :-(

I tried to do several searches online and they recommended me to:
Get the latest SP (I have all the updates now for .net and SQL)
Re-register some .dll's such as dts.dll/pipeline/etc
Change/toggle the PreCompileBinary
Alter the script a little and rebuild.

None of these suggestions have had any success on this error that I'm having. I was wondering if anyone had any insight or had any similar problems as me. Any help would be much appreciated!

Thanks,
-Simon
