Marshal managed string[] to unmanaged char**
- by Vince
This is my c++ struct (Use Multi-Byte Character Set)
typedef struct hookCONFIG {
int threadId;
HWND destination;
const char** gameApps;
const char** profilePaths;
} HOOKCONFIG;
And .Net struct
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
public struct HOOKCONFIG {
public int threadId;
public IntPtr destination;
// MarshalAs?
public string[] gameApps;
// MarshalAs?
public string[] profilePaths;
}
I got some problem that how do I marshal the string array?
When I access the struct variable "profilePaths" in C++ I got an error like this:
An unhandled exception of type 'System.AccessViolationException' occurred in App.exe
Additional information: Attempted to read or write protected memory. This is often an
indication that other memory is corrupt.
MessageBox(0, cfg.profilePaths[0], "Title", MB_OK); // error ... Orz
