How to update a variable?

Question

C++ / C#

Good evening forum users, tell me mediocrity. I am editing the program. In general, as I understand it, here in each thread a new next line is taken from var array = itm.Url.Split(':'); Such a thing is that I need the value in stream (StreamUrl) not to be the same in each stream, but to change in the same way as the proxy. I decided to add a value to the file that parses (:) proxy at the end, which would become stream (StreamUrl), but no matter how I twisted it, I had errors, since I am 0+ in C #. Here is the code without my mediocre attempts, but the seemingly unimportant part is cut out due to the habr limit.
