Question

Say I have simple LINQ extenstion:

var filtered = data.Where(i => i.Count > 0);

I know that this will not evaluated unless I start to use filtered i.e.

foreach(DataItem i in filtered) ...

However I need to create cloned version of data and release data as soon as possible. data can be changed in other thread so I want to get immediate snapshot of it.

How can I force filtered to be evaluated immediately?

Answer 1

var filtered = data.Where(i => i.Count > 0).ToArray();

// or

var filtered = data.Where(i => i.Count > 0).ToList();
