Подскажите как почистить через C# список чтобы оставить только цифровое значение после id

 

[gevolushn]

Регуляркой.

(?<=\{"id":).*(?=,"fi)

Берешь строку из списка, парсишь регуляркой, добавляешь в конец другого списка.
или
Двумя заменами во всем списке.
1) текстом

{"id":

2) регуляркой

,"fi.*
