I have a code example from a SDK, the DLL is written in C and calls for the following:
* 控制权。
Im
[DllImport(@"Dev.dll",
SetLastError = true)]
internal static extern int getAttribute(const RControl *control, RAttribute *attribute);
但是,当然,在界定这一参考职能时,你不能使用混为一谈。
How can I make this work with c#?
由于C#没有参考概念,你实际上无需担心。 在《刑法》方面,《刑法》仍然认为你有一条主线。 因此,您的进口变化如下:
[DllImport(@"Dev.dll", SetLastError = true)]
internal static extern int getAttribute(RControl control, RAttribute attribute);
当然,这假设在C#中已经界定了<代码>RControl和RAttribute。 如果是结构性的,则采用MSDN的例子来界定供P/Invoke使用的结构。 如果是课堂,那就会产生不同的问题。 在这种情况下,如果这些班级是以通信为基础的,则最好能做到。
声明保证,该功能不会改变已过时的物体。 因此,利用这一优势,告诉pin者,在复制时没有点。 适用[In]属性:
[DllImport(@"Dev.dll", SetLastError = true)]
static extern int getAttribute([In] ref RControl control, out RAttribute attribute);
Omit the ref or out keyword if Youclar the debate category as levels und aructs.
