P/invoke : Marshaling two-dimensional char array

[kevou]

hi,

I'm currently trying to deal with this struct from C lib using Platform invoke in C#.

Here is the C struct:

typedef struct
{
  short myshort;
  char Message[MAX_MESSAGE][MAX_MESS_LEN];
} mystruct;
 

This structure is passed as an argument to many functions of the dll I'm exporting.

Here is the C# (marshaled) structure in progress:

[ StructLayout( LayoutKind.Sequential, CharSet=CharSet.Ansi )]
public struct mystruct
{
  public short myshort;
  [MarshalAs(???)]
  ???
}
 

So basically, could you help me defining the equivalent matrix... I guess i need to use marshaling also... Thanks a lot. I've been searching for days...

[MarshalAs(UnmanagedType.ByValArray, SizeConst=MAX_MESSAGE * MAX_MESS_LEN)]
public char[] Message;
