Your array is not even recopied Try this as proof Since our goal is to ultimately replace both large byte arrays and the MemoryStream class, the solution needs to be both writable and of variable length. In order to utilise available memory in the most efficient way, each of these smaller arrays should be equal to (or a multiple of) the size of each block of memory allocated by the operating system. A byte array is passed into the method, and then decompressed. Then the byte array is de-serialized into a MemoryStream with anotherBinaryFormatter. The resulting Object is then returned back to the called. Usage of this object is very straight forward.

Dim mybytearray As Byte() 'this … To get the entire buffer, use the GetBuffer method.

Then the maximum allocation size is 4 GB. Finally, use a byte [] if you need to access the data at any index number. Then use my code block to convert it to a byte array. memoryStream.ToArray() is the byte array. 0.
