.NET Forum / .NET Framework / CLR / November 2006Are there any pure managed object to Byte Array methods?
I want to translate an objects data to a byte array and vice-versa. The closest thing I found is Marshal.StructureToPtr(), and Marshal.PtrToStructure(). However, these functions are meant to copy from managed objects to unmanaged IntPtrs. Is there an equivalent call that does a pure managed to managed byte array copy to and from an object?

There's the BitConverter class, you'll have to do your own layout. If you need to capture anything beyond binary numeric data (class type or handle-linked structures), you're probably looking toward serialization instead. The only problem that I have with serialization is the volume of data that results from serializing a class object. I was hoping to just be able to extract an array of bytes from the class object data. BitConverter only works on primitive types. I put together my own class to do this, but wanted to make sure it was not already available. Basically what I did was encapsulate the Marshal.PtrToStructure() and Marshal.StructureToPtr() methods to do the translation via pinned objects to and from a Byte Array. It seems to work pretty well, but I was not sure if I was duplicating something that was already available. Signature----------------------------------- Ken Varn Senior Software Engineer Diebold Inc.

Yes, I think serialization is overkill for most purposes, it's geared toward schema versioning and reconstructing object graphs with cycles. > I put together my own class to do this, but wanted to make sure it was not > already available.
