>>Hi All, is it possible in a "Linq type way" to set properties of class instances which are in a IList ? , for example I have a list of names and addresses in a list and if there are some that share a certain residential area code (e.g. UK ) I would like to set a property in the instances, hope this makes sense.

List does have a foreach method (http://msdn.microsoft.com/en-us/library/bwabdf9z%28v=vs.110%29.aspx), but its not really recommended (http://blogs.msdn.com/b/ericlippert/archive/2009/05/18/foreach-vs-foreach.aspx). There is also a parallel foreach (http://msdn.microsoft.com/en-us/library/dd992001%28v=vs.110%29.aspx) you could use if setting the value has no side effects.
