Опираясь на монитор, даже если другое приложение является полным экраном в C# ⇐ C#

[Anonymous]

Во -первых, привет, это будет мой первый вопрос. Желаю вам хорошего дня. Подойдя к моему вопросу, создание специального перекрестия поддерживается в CSGO или CS2, но, к сожалению, это не поддерживается в старых играх CS, таких как CS 1.6. По этой причине я хочу нарисовать специальный перекрест непосредственно на мониторе, используя C#.
Я сделал то, что хотел, но единственная проблема заключается в том, что когда приложение является полным экраном, программа прекращает рисование на экране. Как я могу решить эту проблему? Как я могу нарисовать на экране, даже если приложение является полным экраном? Я оставляю свой код ниже, спасибо заранее. < /P>
