Question

C#调用C++DLL出现外部组件异常 DLL里面有两个函数一个能成功运行一个就提示有错误

C++dll
extern "C"
{
#endif

bool __stdcall DownLoadFile(const char* Url, const char* Casename, const char* Filename);
int __stdcall ExecuteFile(const char* hostname);
#ifdef __cplusplus
}
#endif

C#
[DllImport("TCaseDll.dll", CharSet = CharSet.Ansi/*, CallingConvention = CallingConvention.StdCall*/)]
public static extern bool DownLoadFile(string Url, string Casename, string Filename);
[DllImport("TCaseDll.dll", CharSet = CharSet.Ansi/*, CallingConvention CallingConvention.StdCall*/)
public static extern int ExecuteFile(string hostname);

断点调试发现参数都传递正确求高手急啊

是不是用了中文参数，如果是，那么可能是编码导致的问题
