Reads characters from the underlying stream and advances the current position of the stream in accordance with the Encoding used and the specific character being read from the stream.
Assembly: mscorlib (in mscorlib.dll)
The following example shows how to read and write data using memory as a backing store. This example displays a list of invalid file path characters to the console. Although the code tries to display a list of all invalid file path characters, not all of the characters are within the displayable set of characters. Because the list of invalid characters can vary based on the system, output for this code may also vary.
Imports System Imports System.IO Public Class BinaryRW Shared Sub Main() Dim i As Integer = 0 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: ") For i = 0 To invalidPathChars.Length - 1 binWriter.Write(invalidPathChars(i)) Next i ' 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 memoryData( _ CInt(memStream.Length - memStream.Position) - 1) As Char For i = 0 To memoryData.Length - 1 memoryData(i) = Convert.ToChar(binReader.Read()) Next i Console.WriteLine(memoryData) End Sub End Class
