If I have an unmanaged pointer and I want to transfer a specified number

  • 0

If I have an unmanaged pointer and I want to transfer a specified number of bytes from that location to a Byte array, what is the best way to do this?

i.e. what is the equivalent of Marshal.PtrToString* methods but where the destination is a Byte()

Thanks

    Marshal.Copy has overloads for copying byte arrays to/from a pointer.

    By Byte() is this interoperation with VB6 style COM? You why want to check the underlying COM type using the OLE-COM Viewer (included in the Windows SDK tools installed with VS) to open the VB created dll to look at that its typelib says.
