我正在尝试将字符串从C ++控制台应用程序传递到C ++ dll,然后我将其转换为System :: string以发送到C#dll。但字符串是随机字符。请注意,lShutdown实际上是正确的,因为它在dll中定义,所以问题必须在testapp和C ++ dll之间。我之前有过这个工作,但我无法弄清楚我的生活是如何做到的
以下是传递给dll的代码:
void GMSTestAppC::GMSSetup()
{
string processName = "GMSCTestApp";
string progName = "TestApp";
//Directory where program is installed
string progDir = "C:/";
string version = "4.0.0.1";
//Directory for config file
string configDir = "C:/";
//Directory for log files
string logDir = "C:/";
string user = "Smurf";
string shutdownby = "";
Initialize(processName, GetCurrentProcessId(), progName, progDir, version, configDir, logDir, user, shutdownby);
}
这是dll代码:
bool Initialize(std::string& processName, int processID, std::string& programName, std::string& programDir, std::string& version, std::string& configDir, std::string& logDir, std::string& currentUser, std::string& lastShutDownBy)
{
String^ pName = gcnew String(processName.c_str());
String^ progName = gcnew String(programName.c_str());
String^ progDir = gcnew String(programDir.c_str());
String^ cDir = gcnew String(configDir.c_str());
String^ lDir = gcnew String(logDir.c_str());
String^ cUser = gcnew String(currentUser.c_str());
String^ lShutdown = gcnew String("test");
GMS::GMSVersion fv;
sscanf_s(version.c_str(), "%d.%d.%d.%d", &fv.Major, &fv.Minor, &fv.Revision, &fv.Build);
int pID = int(processID);
Return GMS::Initialize(pName, pID, progName, progDir, fv, cDir, lDir, cUser, lShutdown);
}
这是我实际得到的:
Sent: <InitializeProgram>
<TimeStamp>2018-01-22T14:34:37.6152709+00:00</TimeStamp>
<PID>13504</PID>
<ProcessName>(÷'</ProcessName>
<ProgramName>Ðð'</ProgramName>
<ProgramDir>°ñ'</ProgramDir>
<Version>0.0.0.0</Version>
<ConfigDir>^ô'</ConfigDir>
<LogDir>èñ'</LogDir>
<CurrentUser>÷'</CurrentUser>
<LastShutDownBy>test</LastShutDownBy>
</InitializeProgram>
每次运行程序时出现的字符都不同
非常感谢任何帮助

如果您使用的是C ++ 11(最常用的),可以尝试使用std::u32string
。它消除了使用std::wstring
的需要,并且是跨平台的标准。
