How to empty viriables?

[convict29]

Hey is there any fast way to bulk empty or set blank some of my variables(20 of them) ?
Im not a coder but i guess this might be possible with a C#. Thanks in advance!

project.Variables["varname1"].Value = String.Empty;
project.Variables["varname2"].Value = String.Empty;
project.Variables["varname3"].Value = String.Empty;
