推荐答案

您要导入什么功能?

请查看http://www.pinvoke.net/以获取示例和此类示例.

What function are you trying to import?

Check out http://www.pinvoke.net/ for examples and such.

您的函数声明(与其他任何方法一样)都需要在类级别进行声明.您不能在其他方法中声明它们.

换句话说，在您的Main方法之外执行此操作.在调用本机函数时，标准是声明一个名为NativeMethods的类并将其放在其中.

Your function declarations (like any other methods) need to be declared at the class level. You cannot declare them within another method.

In other words, do it outside of your Main method. As you are calling native functions, the standard is to declare a class called NativeMethods and put them in there.
