If I have variable 1 to be empty, I’ll run a certain process. If I have variable 2 to be empty, I’ll run another process. If I have variable 3 empty, I’ll run another process. How am I suppose to use a switch function in this case to test whether a variable is empty or not?
If your type of variables is String, the following will work.
Note: TypeArgument of Switch activity is Int32.
