C#调用C++动态库出错，高人帮忙解决下，谢谢

[wnyunn]

typedef struct
{
WORD MSGNum;
SMSG_STRUCT SelfMSG[4096];
}SFRAME_STRUCT;
typedef struct
{
BOOL RetryEnable;
BYTE ChannelSelect;
DWORD InterMSGGapTime;
BYTE MSGFormat;
WORD MSGBlock[37];
}SMSG_STRUCT;

void __stdcall BC_SendDataFrame(SFRAME_STRUCT *Frame);


转换成C#调用出错
[System.Runtime.InteropServices.DllImportAttribute("M1553CFB.dll", EntryPoint = "BC_SendDataFrame", CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall)]
public static extern void BC_SendDataFrame(SFRAME_STRUCT Frame);



哪位高人帮忙解决一下，谢谢

如果你SFRAME_STRUCT定义正确,且数组正确初始化的话,那么
public static extern void BC_SendDataFrame(SFRAME_STRUCT Frame);
改成
public static extern void BC_SendDataFrame(ref SFRAME_STRUCT Frame);

应该就可以了

正解，呵呵
