I'm trying to deserialize a memory stream sent from a MS .Net3.5 application via UDP to a Labview client. My options seemed to be: 1) a CIN - which I have mostly done and can probably finish up 2) a DLL - but I can't figure out how to invoke managed code 3) use the LV .Net Constructor node and Invoke node. This seemed to be the simplest, but I cannot get the deserialization to work. To test, --I create a Binary Formatter (Constructor Node) and a Memory Stream (Constructor Node), ,then use the Binary Formatter (Invoke Node) to serialize a .Net Object dreated from an array. This seems to work, though I cannot figure out how to 'see' the serialized stream. The main problem is deserialization, where I cannot create any method (using Invoke Node) of the Binary formatter that allows me to input the stream. The equivalent c++ code is fairly simple: Create a stream and serialize the object, and send to byte array: MemoryStream ms = new MemoryStream(); string theSerializedObject; System.Runtime.Serialization.Formatters.Binary.BinaryFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter(); formatter.Serialize(ms, ObjectToSerialize); byte[] thisByteArray = ms.ToArray(); Grab byte array from transmitted string, create the mem stream, and deserialize the data: byte[] thisByteArray = Convert.FromBase64String(StringToDeserialize); MemoryStream ms = new MemoryStream(thisByteArray); System.Runtime.Serialization.Formatters.Binary.BinaryFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter(); Attached is an attempt to duplicate these steps in LV, without any luck. I appreciate any ideas or samples. Thanks, Brian

Use .Net deserialization in LV?

I would recommend creating a new thread for this topic. I belive you will get a stronger community response because this thread hasn't been active since 2008. Also to better understand what you are trying to do it would be helpful if you included your LabVIEW code in the new thread you create.
