Question

I’m trying to get certain keys from the Request.Form.AllKeys string array by using the following:

var result = keys.Where(key => key.StartsWith("added"));

The result is “The name ‘result’ does not exist in the current context” no matter what I do.

I’ve also tried:

var result = (from keys in Request.Form.AllKeys
              where keys.StartsWith("added")
              select keys).ToArray();

Same thing.

I’m new to Linq and Lambda expressions and all, so please forgive the ignorance.

Regards,
Jacques

Answer 1

I found the answer to my question: Delayed execution.

When I actually executed the code and then followed it up by using result.Any() the expression was executed and turned out the correct results.
