Question

I’m quite new to Linq. I have something like this:

dict = fullGatewayResponse.
Split(',').ToDictionary(key => key.Split('=')[0], value => value.Split('=')[1])

This works fine but for obvious reasons I don’t want the split() method to be called twice.
How can I do that ?

Thanks for all your responses :), but I can only choose one.

You can convert each item to an array before ToDictionary by using Select:

dict = fullGatewayResponse.Split(',')
                          .Select(item => item.Split('='))
                          .ToDictionary(keySelector:     parts => parts[0],
                                        elementSelector: parts => parts[1]);
