//调用
private static void test ()
{
MyScreen sc = new MyScreen ();
sc.Height = 32;
sc.DeviceName = “sb233″;

}

//结构体定义
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]

public int Height;
};
[DllImport("./so.so" , EntryPoint = "test", CallingConvention = CallingConvention.Cdecl)]
public unsafe static extern void test (ref MyScreen p, int size);
