Can all 'for' loops be replaced with a LINQ statement?

Question

Is it possible to write the following \'foreach\' as a LINQ statement, and I guess the more general question can any for loop be replaced by a LINQ statement.

I\'m not i

Sure. Heck, you can replace arithmetic with LINQ queries:

But you shouldn't.

The purpose of a query expression is to represent a query operation. The purpose of a "for" loop is to iterate over a particular statement so as to have its side-effects executed multiple times. Those are frequently very different. I encourage replacing loops whose purpose is merely to query data with higher-level constructs that more clearly query the data. I strongly discourage replacing side-effect-generating code with query comprehensions, though doing so is possible.
