Dim mybytearray As Byte() 'this … To get the entire buffer, use the GetBuffer method. This method returns a copy of the contents of the MemoryStream as a byte array. If the current instance was constructed on a provided byte array, a copy of the section of the array to which this instance has access is returned. See the MemoryStream constructor for details.

byte [] myByteArray = new byte [10]; MemoryStream stream = new MemoryStream (); stream.Write (myByteArray, 0, myByteArray.Length); Here’s a solution in less lines of code. It creates a new, non I need to convert that byte array to a memorystream. Here is the piece with the lead-up code: byte [] buffer = new byte [blobSize]; IntPtr source = Marshal .AllocHGlobal (blobSize); FPStream streamRef = new FPStream (source, blobSize, FPStream.

The answer is future proofing! The DeSerialize method works the other way around. A byte array is passed into the method, and then decompressed. Then the byte array is de-serialized into a MemoryStream with another BinaryFormatter.

This would allow the client to eliminate any memory churn when serializing the data since data would be serialized to reusable byte arrays. Now, you may wonder why I didn't use one of the many libraries that provide implementations of MemoryStream that reuse pooled arrays, like Microsoft.IO.RecyclableMemoryStream? The answer is future proofing! As you say.. i need to use the 2nd code. using "MemoryStream" to read a file into an Array of Bytes.. then i create a for loop to file length byte after byte.

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 Appending it to a MemoryStream (per your subject line) is easy, just call the Stream.Write method. You can't append things to an array since arrays have a fixed length. But you can create a new array and write both parts to it using Array.Copy or Buffer.BlockCopy. Mattias--Mattias Sjögren [MVP] mattias @ mvps.org You're trying to generically convert arrays to byte representations then. Try using a StreamWriter object with a MemoryStream.
