Yeah, your advice proven to be precious. I'm trying to implement my own ISerializable using compression, but I found a problem Implementing the GetObjectData, it would be usefull to get a byte array rappresenting the class, and Isually do so using this code System.Runtime.Serialization.Formatters.Binary.Bin aryFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.Bin aryFormatter(); formatter.Serialize(buffer, this); Byte[] ByteObject=new Byte[buffer.Length]; buffer.Read(ByteObject,0,buffer.Length] however, since I'm implementing my own ISerializable I cannot call formatter.Serializable since it would end up in a mess. Could you give me any other advice? Thanks Cristian Mori implementing the GlobalObjec "Steven Cheng[MSFT]" wrote: Thanks for your followup Cristian, So since you mentioned that your actual class will hold about 500kb data, I'm afraid this is really a big pressure for cross appdomain communication. Also, for class that apply the [Serializable] attribute, the .net framework automatically determine the runtime serialize structure, we haven't any particular means to improve it. If your data's structure or members is of particular type which can be compressed, you can consider manually implement the ISerializable interface for your class.

Hi Cristian, Thanks for your response. For the Custom ISerializable interface, in the GetObjectData method, generally, it will let us add the serilization data of our class into the SerilizationInfo through AddValue method. For example, which a class contains string, int and other type members, we can only add some of them, as for string content, we can perform encoding and compression on it. There is no means for us to convert a object instance directly into byte array without use binaryFormatter , this is unlike in c++. So what's your class's members, just byte array? If most of them are string contents, we can perform encoding and compression on them. If only binary datas, I'm afraid, we haven't any good means to compress them. Also, to get byte[] from the object instance on the fly, we could only use the BinaryFormatter inside our custom ISerializable interface.

Hi Steven. Sorry but I didn't fully understand your reply. I tryed to use the BinaryFormatter inside the custom ISerializable interface, but , I think, since the BinaryFormatter rely on the serializzation, calling it on the same class will cause a recursive operation. This is the problem I got. Another question for you. I tryed to change the class so that it is no longer serializable but it derive from MarshallByRefObject. The situation is even worst! The same function now it is very very very slow! I think this is due to the big amount of cross-appdomain calls done on each chage. What kind of remoting use the .NET framework on this situation? Is there a way to speed up or not? Thanks again! Cristian Mori "Steven Cheng[MSFT]" wrote: Hi Cristian, Thanks for your response. For the Custom ISerializable interface, in the GetObjectData method, generally, it will let us add the serilization data of our class into the SerilizationInfo through AddValue method. For example, which a class contains string, int and other type members, we can only add some of them, as for string content, we can perform encoding and compression on it. There is no means for us to convert a object instance directly into byte array without use binaryFormatter , this is unlike in c++. So what's your class's members, just byte array? If most of them are string contents, we can perform encoding and compression on them. If only binary datas, I'm afraid, we haven't any good means to compress them. Also, to get byte[] from the object instance on the fly, we could only use the BinaryFormatter inside our custom ISerializable interface.

Thanks for your response Cristian, As for the binary formatter, of course we can not direclty call it on the object itself. Since we are manually control the serlization, we can directory use it on our custom object's member objects/ fields. Also, MarshalByRef is not possible since that'll cause more time on cross boundary reference management. What does your custom object currently hold that occupy the main size? String or nested custom class instances?

if so, we should locate one of the nested class member which occupy the most size. Also, what's the type of the data that comsume the most memory? Anyway, to convert class instance into memory, we could not but utilize the binaryfomatter since .NET dosn't support random access on raw memory of the object instances.
