The following code example shows how to read and write Double data to memory by using the BinaryReader and BinaryWriter classes on top of the MemoryStream class.
Imports System Imports System.IO Public Class BinaryRW Shared Sub Main() Dim i As Integer Const upperBound As Integer = 1000 ' Create random data to write to the stream. Dim dataArray(upperBound) As Double Dim randomGenerator As New Random() For i = 0 To upperBound dataArray(i) = 100.1 * randomGenerator.NextDouble() Next i Dim binWriter As New BinaryWriter(New MemoryStream()) Try ' Write data to the stream. Console.WriteLine("Writing data to the stream.") For i = 0 To upperBound binWriter.Write(dataArray(i)) Next i ' Create a reader using the stream from the writer. Dim binReader As New BinaryReader(binWriter.BaseStream) ' Return to the beginning of the stream. binReader.BaseStream.Position = 0 ' Read and verify the data. Try Console.WriteLine("Verifying the written data.") For i = 0 To upperBound If binReader.ReadDouble() <> dataArray(i) Then Console.WriteLine("Error writing data.") Exit For End If Next i Console.WriteLine("The data was written and verified.") Catch ex As EndOfStreamException Console.WriteLine("Error writing data: {0}.", _ ex.GetType().Name) End Try Finally binWriter.Close() End Try End Sub End Class
