How to call Unmanaged DLL from C# application ?
How to call Unmanaged DLL from C# application ?
I develeoped the win32 DLL.
I added the code in the DLL header file as follows :
#ifdef DLLDIR_EX
#define DLLDIR __declspec(dllexport) // export DLL information
#else
#define DLLDIR __declspec(dllimport) // import DLL information
#endif
extern "C"
{
bool DLLDIR GetSysInfo(char* pszSystemName);
};
DLL implementation file I added its defn
How I accessed the DLL in C# ?
VC++ DLL is an Unmanaged code.
This is following way How I accessed that file...
I just copied the .DLL and .LIB files from my DLL project.
and copied it to the debug folder of the C# application
Within C# application
using System.Runtime.InteropServices; // For Interoperability
[DllImport("RemoteSystemDLL.dll")]
public static extern bool GetSysInfo(StringBuilder buf);
and called this GetSysInfo() fn in my application.
// this is the C++ function exposed by the dll
