Uipath string null

Question

can anyone tell me how to check for unassigned string in uipath ?

Answer 1

There are a lot of ways to that, few that pop into my mind are : 

 initialize variables with empty strings(""). that makes it easy to check it with '='  operator.

  another way to go about it would be .Net 'String.IsNullOrEmpty Method'  Method.

if you are new to uipath you should consider watching video tutorials and if possible join RPA training
