Looping through a list of Actions

Question

I can\'t understand how to loop through an Action list. When I try it, I end up with the values being the same as the previous iteration.

Here\'s the co

This behaviour is conditionize by Closures.

The variable that is present in your lambda is a reference and not value copy. That means that points to the latest value assumed by str, which is "ghi" in your case. That's why for every call it just goes to the same memory location and recovers, naturally, same value.

If you write the code, like in answers provided, you force a C# compiler to regenerate a new value each time, so a new address will be passed to the labmda, so every lambda will have it's own variable.

By the way, if I'm not mistake, C# team promise to fix this non natural behaviour in C# 5.0. So it's better to check their blog on this subject for future updates.
