如何在C＃中访问C ++ DLL的功能
这是DLL的原型：
NOMANGLE int CCONV SSPSendCommand (SSP_COMMAND * cmd, SSP_COMMAND_INFO * sspInfo);
NOMANGLE int CCONV OpenSSPComPort (SSP_COMMAND * cmd);
NOMANGLE int CCONV OpenSSPComPort2 (SSP_COMMAND * cmd);
NOMANGLE int CCONV OpenSSPComPortUSB (SSP_COMMAND * cmd);
NOMANGLE int CCONV CloseSSPComPort (void);
NOMANGLE int CCONV CloseSSPComPort2 (void);
NOMANGLE int CCONV CloseSSPComPortUSB (void);
NOMANGLE int CCONV DownloadFileToTarget (char * szFilename, int cPort, unsigned char sspAddress);
NOMANGLE long CCONV GetRamDownloadStatus (RAM_UPDATE_STATUS * rmData);
NOMANGLE int CCONV SetPortCloseOption (unsigned int md);
NOMANGLE int CCONV OpenCCTComPort (int PortNumber);
NOMANGLE int CCONV CloseCCTComPort (void);
NOMANGLE int CCONV CCTSendPacket (unsigned char * pkt, unsigned char * length);
[DllImport (\"ITLSSPProc.dll\")]
private extern static IntPtr SSP_COMMAND ();
[DllImport (\"ITLSSPProc.dll\")]
private static extern int OpenSSPComPort (SSP_COMMAND smd);

不是函数。这是一种类型。仅导入功能。要么将其视为不透明的“ 4”，要么为其创建适当的“ 5”表示。 将其用作不透明的：有关使用结构的信息，请参见从MSDN传递结构并在C＃中定义ѭ8。 （此链接包含入门所需的一切，包括相关示例）。 快乐的编码。联海
