Add string between strings if they are not null or empty

Hi there.
I am trying to do a concatenation of strings with a separator on the condition the string element is not empty. if it is, skip it.

I found some references to a C# code looking like this

var1 = string.Join(“,”, s_array.Where(s => !string.IsNullOrEmpty(s)))

where var1 is a string datatype and S_array is an array of strings.

Any ideas other than looping through the array? I want a quick and short assign activity.


Hi @markvax

Just to close this topic:

  • nowadays, you could use the C# project and use your code as is
  • use this snipped for the project:
string.Join(",", variable1.Where(function(s) not String.IsNullOrEmpty(s)))

Hi Maciej,
Thanks for providing the code snippet. Its been 3 years and I forgot what i needed it for:)

I’ll keep it handy in my cheat sheet for future use.
