Programmatically get ScriptTask source code

Hi am trying without luck to load a package which contains a ScriptTask and read the source code of that task.

I can load the package and get the ScriptTask no problem.
However i am not sure how to get the source code.
I know i have to use the ScriptTaskCodeProvider and i assume the GetSourceCode() method.

This is what i have so far

ScriptTask scriptTask = taskHost.InnerObject as ScriptTask;
ScriptTaskCodeProvider codeProvider = new ScriptTaskCodeProvider();
codeProvider.LoadFromTask(scriptTask);
string sourceCode = codeProvider.GetSourceCode(scriptTask.VsaProjectName);

Any assistance greatly appreciated.

Cheers
Richard.

Application application = new Application();

Package package = application.LoadPackage(@."C:\Yukon\ISPlaying\ISPlaying\Package14.dtsx", null);

TaskHost taskHost = package.Executables[0] as TaskHost;

ScriptTask scriptTask = taskHost.InnerObject as ScriptTask;

ScriptTaskCodeProvider codeProvider = new ScriptTaskCodeProvider();

codeProvider.LoadFromTask(scriptTask);

string script = codeProvider.GetSourceCode(String.Format("dts://Scripts/{0}/ScriptMain.vsaitem", scriptTask.VsaProjectName));
