关于c＃：无法声明名为“port”的局部变量

A local variable named 'port' cannot be declared

本问题已经有最佳答案，请猛点这里访问。

我正在尝试构建一个Arduino项目，通过开放硬件监视器来测量CPU和GPU温度，现在我在C应用程序中遇到了问题。

它在第45行给出了这个错误：

A local variable named 'port' cannot be declared in this scope
because it would give a different meaning to 'port', which is already
used in a 'parent or current' scope to denote something else

我能得到帮助吗？非常感谢你！
