Clear all variables except one

[Cyd]

Hello,

I am using this C# code to clear all variables :

foreach(string key in project.Variables.Keys)
    project.Variables[key].Value = string.Empty;

Now I need to clear all variables except my counter {-Variable.counter-}. Does someone have an idea how I can do this ?

foreach(string key in project.Variables.Keys)
    if( !(new string[]{"counter"}).Contains(key))project.Variables[key].Value = string.Empty;
