How to pass InOutArgument to dynamic activity and later read them RRS feed

  • Question

  • In my code in execute method of activity i am executing a dynamic loaded xaml and pass in arguments :


    Literal<long> InTransactionId = new Literal<long>();

    InTransactionId.GetType().GetProperty("Value").SetValue(InTransactionId, TransactionId.Get(context), null);

    (_activity.Properties["TransactionId"].Value as InArgument).Expression = InTransactionId as ActivityWithResult;

    and it is working fine.
    but how should i pass inoutargument so that my inoutargument will changed by dynamic xaml and these changes reflected to workflow also which is calling this dynamic loaded xaml workflow.

  • Hi,

    You can try pass in an Object instead of long. since object is a reference type, value changed inside workflow can also be accessed in the workflow host, where workflow is created and executed.

    Hope this helps
