I am serializing an structure into a MemoryStream and I want to save and load the serialized structure.
You may use MemoryStream. CopyTo supported in framework version 4. If the files are large, then it's worth noting that the reading operation will use twice as much memory as the total file size.
One solution to that is to create the MemoryStream from the byte array - the following code assumes you won't then write to that stream. My research below shows that the internal buffer is the same byte array as you pass it, so it should save memory. Originally the implementation of this class has been posted here.
This code works for me a lot. Thank you for your interest in this question.

So, How to Save a MemoryStream into a file and also load it back from file? Ashkan Mobayen Khiabani Mahdi Ghiasi 4, 14 54 If you need to save to a file, why are you using a MemoryStream? Oded What should I use? Can you give me an example? WriteTo fileStream ; Update: CopyTo memoryStream ; memoryStream.
CopyTo didn't seem to work for me, while WriteTo did. I think perhaps it was because my memoryStream.
Yes that is correct. The difference between them is that CopyTo copies from whatever the current position is instead of always from the begining like WriteTo does. Begin ; before CopyTo will set the current position to 0, so that CopyTo will copy the complete stream. Assuming that MemoryStream name is ms. This code writes down MemoryStream to a file: Read bytes, 0, int ms. Write bytes, 0, bytes. Read bytes, 0, int file.
I have an embedded DLL in my app and I need to write it to the filesystem at runtime. I have this so far: Dim _assembly As Assembly = cocktail24.infocutingAssembly. Writes a block of bytes to the file stream. Namespace: VB. Copy // Write the cocktail24.info(cocktail24.infoes. Use the FileStream class to read from, write to, (in Visual Basic). size of the file and any other processes that could affect the position of the file stream. This topic shows different ways you can write text to a file cocktail24.info and closes the stream. shows how to write text to a new file and append new. Stream. Write Method (Byte VB. Copy. public abstract void Write(byte  buffer File and Stream I-O How to: Read Text from a File.
Write bytes, link, int file. Create in the read sample vs FileMode. In the first code block, instead of manually copying memory stream to array, you can use built-in ms.
It's important to set ms. This works with old versions of. Fernando68 the construct using Rob Church 4, 1 28 WriteTo file ; file.
