The following code example shows how to read and write data using memory as a backing store.
Imports System Imports System.IO Public Class BinaryRW Shared Sub Main() Dim invalidPathChars() As Char = Path.InvalidPathChars Dim memStream As new MemoryStream() Dim binWriter As New BinaryWriter(memStream) ' Write to memory. binWriter.Write("Invalid file path characters are: ") binWriter.Write(Path.InvalidPathChars, 0, _ Path.InvalidPathChars.Length) ' Create the reader using the same MemoryStream ' as used with the writer. Dim binReader As New BinaryReader(memStream) ' Set Position to the beginning of the stream. memStream.Position = 0 ' Read the data from memory and write it to the console. Console.Write(binReader.ReadString()) Dim upperBound As Integer = _ CInt(memStream.Length - memStream.Position) - 1 Dim memoryData(upperBound) As Char binReader.Read(memoryData, 0, upperBound) Console.WriteLine(memoryData) End Sub End Class
