C#引用C++ Dll问题

C/C++ code

typedef struct _COMMPORTCONFIG {DWORD BaudRate; // baud rateDWORD ByteSize; // number of bits/byte, 4-8DWORD Parity; // 0-4=no,odd,even,mark,spaceDWORD StopBits; // 0,1,2 = 1, 1.5, 2DWORD fOutxCtsFlow; // CTS Flow Control} COMMPORTCONFIG;C/C++:BOOL MetrocomInitCommunication(int i_port, COMMPORTCONFIG * p_config);

现在我如何转成C#可以引用的,还有要怎么调用?

[解决办法]
DWORD可以使用Int类型，在C#里声明Struct来对应_COMMPORTCONFIG ，然后像调用API一样来调用这个C++的函数，使用Ref传递结构。
[解决办法]
类似的，看看吧

C# code

DLL  传递结构   （见代码）BOOL PtInRect(const RECT *lprc, POINT pt); using System.Runtime.InteropServices; [StructLayout(LayoutKind.Sequential)] public struct Point {public int x; public int y;} [StructLayout(LayoutKind.Explicit)] public struct Rect { [FieldOffset(0)] public int left; [FieldOffset(4)] public int top;[FieldOffset(8)] public int right; [FieldOffset(12)] public int bottom;} Class XXXX { [DllImport("User32.dll")] public static extern bool PtInRect(ref  Rect r, Point p); }
[解决办法]
  public struct COMMPORTCONFIG
       {
           int BaudRate; // baud rate
           int ByteSize; // number of bits/byte, 4-8
           int Parity; // 0-4=no,odd,even,mark,space
           int StopBits; // 0,1,2 = 1, 1.5, 2
           int fOutxCtsFlow; // CTS Flow Control
       }

       [DllImport("DLL文件名")]
       public static extern bool MetrocomInitCommunication(int i_port, ref COMMPORTCONFIG p_config);


[解决办法]
C# code
[DllImport("你DLL名称")] public static extern bool  MetrocomInitCommunication(int i_port, ref COMMPORTCONFIG  p_config);[StructLayout(LayoutKind.Sequential)] public struct _COMMPORTCONFIG {int  BaudRate; // baud rateint  ByteSize; // number of bits/byte, 4-8int  Parity; // 0-4=no,odd,even,mark,spaceint  StopBits; // 0,1,2 = 1, 1.5, 2int  fOutxCtsFlow; // CTS Flow Control}int i_port;COMMPORTCONFIG  p_config=new COMMPORTCONFIG ();MetrocomInitCommunication(i_port, ref  p_config);
[解决办法]
探讨

C# code

[DllImport("你DLL名称")] 
public static extern bool  MetrocomInitCommunication(int i_port, ref COMMPORTCONFIG  p_config);

[StructLayout(LayoutKind.Sequential)] 
public struct _COMMPORTCONFIG {
int  BaudRate; // baud rate
int  ByteSize; // number of bits/byte, 4-8
int  Parity; // 0-4=no,odd,even,mark,space
int  StopBits; // 0,1,2 = 1, 1.5, 2
int  fOutxCtsFlow; // CTS Flow Control
}
