Delete Attachments?

I know how to Add and Query attachments, but am unsure on how to delete attachments. I am stuck on the 'Attachment Ids' argument. I know how to get my ID through the Query Attachments activity, but am confused on how to convert my ID into a StringArray for the said argument as  I will only have one return. The user picks an attachment related to the record from a form and that variable is an object.  Any examples? Ideas?

  how about this?

  (1) Declare a variable with the type "Array of String" , ie. String[]?

  (2) assign to the variable using the Cast <T> Activity with the value like '{string.Format("{0}", idObj)' where idObj is the attachment id with Object type you got.

  Thanks - but no luck. I got an invalid Cast error

  Here's what I tried... maybe you can correct me where I went wrong?

  SelectedAttachmentID = (obj variable of attachment from form) 

  Declared variable y as System.String[]

  Casting (type: <String[]> where y =  (string.Format("{0}", SelectedAttachmentID))

  ?

  Ryan,

  Check if your AttachmentID is existing valid one value first.

  This is my testing workflow.

  Should be 

  Casting (type: <String[]> where y =  {string.Format("{0}", SelectedAttachmentID)}

   

  Use Curly brace ({})

  Thank you! That did work. Your original email suggested using the syntax:  '{string.Format("{0}", idObj)'... no curly brace at the end, so I made some assumptions.
