SubString c учетом регистра С#

http://qaru.site/questions/323456/find-a-substring-in-a-case-insensitive-way-c

Contains() - не хиляет без учета регистра

нет версии без учета регистра. Вместо этого используйте IndexOf (или регулярное выражение, хотя это не рекомендуется и излишне).

string string1 = "my string";
string string2 = "string";
bool isContained = string1.IndexOf(string2, StringComparison.OrdinalIgnoreCase) >= 0;


StringComparison.OrdinalIgnoreCase обычно используется для более "программируемого" текста, такого как пути или константы, которые вы могли сгенерировать, и является самым быстрым средством сравнения строк. Для текстовых строк, которые являются лингвистическими, используйте StringComparison.CurrentCultureIgnoreCase или StringComparison.InvariantCultureIgnoreCase.

Best way to reverse a string

It seems that Xor can be faster for short strings.
