URGENT: Unix/Windows Struct cast problem

[Tamir Khason]

Follwing the struct:
[StructLayout(LayoutKind.Sequential, Pack=1, CharSet=CharSet.Ansi)]

public struct TpSomeMsgRep

{

public uint SomeId;

[MarshalAs(UnmanagedType.ByValArray, SizeConst=2)]

public Byte[] notinuse1;

[MarshalAs(UnmanagedType.ByValArray, SizeConst=674)]

public Byte[] theMainPart;

}

This used to cast from buffer, recieved by TCP from C++ Program, like this:

oMsgRes= (mm.TpSomeMsgRep )SomeBuffer;

This work fine with Unix server. once transfer to Windows I can not cast to
the structure.

PLEASE HELP HELP HELP!

Would be great if you could provide the code how you are receiving the
packets in C# so we can see how to help you.

What and how are you casting, if you want to cast a byte array to your
struct, you must use marshalling functionality:

byte [] buf = * received * ;
GCHandle h = GCHandle.Alloc( buf, GCHandleType.Pinned );
TpSomeMsgRep rep = (TpSomeMsgRep)Marshal.PtrToStruct(h.AddrOfPinnedOb ject(),
typeof(TpSomeMsgRep));
h.Free();
// use rep
If you need something else, be more specific.

You're are still not very clear. Is this server written in c++ compiled for

I don't think struct differ from one platform to another. Struct alignment
may cause different struct layout's but that is compiler dependent not
platform.

What's exactly is the problem you have ? Does PtrToStruct throw ?
Unexpected data ??

What is ObjectSerializedFromBinaryStream? It seems not to be part of the

If you want that we help you you have to provive more information for

This just name of variable to explain where ti tooked from :)

Anyway there is no way to provide full source it a lot of classes with
relations etc.
The point is that there are diferences between unix and windows TCP or
binary stream....

binary stream....

I do not believe that. The bytes can be read from the stream the same way
you put them in.
The marshaller will take care that the byte order (big endian/little endian)
in your struct's variables will be ok.

Remember that you have to pass the correct type to PtrToStruct, otherwise
itt will output the wrong type.

You should use the same pack that was used to generate the original struct.
If you are not sure, compare their sizes (your struct and the receiced
packet).
If it is the same your pack size is correct.

if the cast from ObjectSerializedFromBinaryStream failed try to display the
type of the generated object:

Console.WriteLine(ObjectSerializedFromBinaryStream ().GetType());

maybe that can give you the idea what got wrong.

However if you would post the piece of code you are using for receiving the
packets you have much bigger chances somebody here can solve your problem.

The problem is WHAT I'M passing in.
I revieve the stream from C++ server.
When it was in UNIX enviroment - everything worked ok, but once they
treanfer to Windows the problem begun. There are same structures, but as far
as I understand , not the same stream - thet's the single explanation I can
think about...

Anyway there is no way to provide full source it a lot of classes with
relations etc.
The point is that there are diferences between unix and windows TCP or
binary stream....

I do not believe that. The bytes can be read from the stream the same way
you put them in.
The marshaller will take care that the byte order (big endian/little

endian) in your struct's variables will be ok.

Remember that you have to pass the correct type to PtrToStruct, otherwise
itt will output the wrong type.

You should use the same pack that was used to generate the original struct. If you are not sure, compare their sizes (your struct and the receiced
packet).
If it is the same your pack size is correct.

if the cast from ObjectSerializedFromBinaryStream failed try to display the type of the generated object:

Console.WriteLine(ObjectSerializedFromBinaryStream ().GetType());

Not sure what you mean with:

the type I recieved is Object

Threfore, Just the piece of code that receives the packets and re-assemble
them into the struct could be enough.

Simple Casting. This server using its own protocol over TCP to construct
structures and I'm on other side have the same structures to recieve
If the server is run on Sun and the client can receive it with Pack=1, then
I suspect that structure alignment for the Sun compilation is 1 byte, not 4.

Dunno if it will help, but I don't think it's much work to see if Pack=4 for
the client helps when the server runs on Windows.

You have a field of type uint in your struct. Maybe it is 32bit on windows
but it is 64 on sun, that could be the problem.

Yes, Sun has motorola byte order. Thinking about it a while I do not believe
that the marshaller converts the byteorder automatically because it doesn't
know the byteorder which the packet has. It would be great if I could tell
the marshaller to convert is automatically.
But I do not believe this has something to do which the error the OP is
getting.

Not sure what you mean with:

the type I recieved is Object

Threfore, Just the piece of code that receives the packets and re-assemble
them into the struct could be enough.

You, and everyone else, can drop the Urgent Urgent Urgent crap
from your posts.

Lack of planning on your part does not constititute an emergency on

instead of adding always 2 to the number of bytes in your method you should
declare the
field "public uint SomeId;" as "ulong" instead because the sun machine
certainly has 64 bit integers.

just a few comments:

public static object RawDeserializeEx(ref byte[] rawdatas, Type anytype )
"ref" is unnessecary because you don't modify the reference "rawdatas", just
its content.
buffer = IntPtr.Zero;
unnessecary it will automatically be freed when it goes out of scope.
