Stream is a representation of bytes. Both these classes derive from the Stream class which is abstract by definition. As the name suggests, a FileStream reads and writes to a file whereas a MemoryStream reads and writes to the memory. So it relates to where the stream is stored. Now it depends how you plan … Read more
In .NET 4, you can use Stream.CopyTo to copy a stream, instead of the home-brew methods listed in the other answers. MemoryStream _ms; public MyClass(Stream sourceStream) _ms = new MemoryStream(); sourceStream.CopyTo(_ms); }
This is because the StreamReader closes the underlying stream automatically when being disposed of. The using statement does this automatically. However, the StreamWriter you’re using is still trying to work on the stream (also, the using statement for the writer is now trying to dispose of the StreamWriter, which is then trying to close the … Read more
You won’t leak anything – at least in the current implementation. Calling Dispose won’t clean up the memory used by MemoryStream any faster. It will stop your stream from being viable for Read/Write calls after the call, which may or may not be useful to you. If you’re absolutely sure that you never want to … Read more
You may use MemoryStream.WriteTo or Stream.CopyTo (supported in framework version 4.5.2, 4.5.1, 4.5, 4) methods to write content of memory stream to another stream. memoryStream.WriteTo(fileStream); Update: fileStream.CopyTo(memoryStream); memoryStream.CopyTo(fileStream);
This sample shows how to read and write a string to a MemoryStream. Imports System.IO Module Module1 Sub Main() ‘ We don’t need to dispose any of the MemoryStream ‘ because it is a managed object. However, just for ‘ good practice, we’ll close the MemoryStream. Using ms As New MemoryStream Dim sw As New … Read more
