Is converting a NameValueCollection to a querystring using a c# lambda efficient?

Question

In researching how to convert a NameValueCollection to a querystring, I have come across different methods. I am curious if the shorter lambda syntax is as efficient as it coul

Answer 1

NameValueCollection's ToString method will build the query string for you. I haven't done any benchmarking, but I'd imagine the implementation would be more efficient than something using lambdas or foreach.

(The ToString solution doesn't seem to be well-documented; I only found it because this answer used it in a code sample.)
