Creating a Writer

The following code example creates a writer, which is a class that can take data of some type and convert it to a byte array that can be passed to a stream.

Imports System
Imports System.IO

Public Class MyWriter
    Private s As Stream

    Public Sub New(stream As Stream)
        s = stream
    End Sub

    Public Sub WriteDouble(myData As Double)
        Dim b() As Byte = BitConverter.GetBytes(myData)
        ' GetBytes is a binary representation of a double data type.
        s.Write(b, 0, b.Length)
    End Sub

    Public Sub Close()
        s.Close()
    End Sub
End Class

using System;
using System.IO;

public class MyWriter
{
    private Stream s;

    public MyWriter(Stream stream)
    {
        s = stream;
    }

    public void WriteDouble(double myData)
    {
        byte[] b = BitConverter.GetBytes(myData);
        // GetBytes is a binary representation of a double data type.
        s.Write(b, 0, b.Length);
    }

    public void Close()
    {
        s.Close();
    }
}

using namespace System;
using namespace System::IO;

public ref class MyWriter
{
private:
    Stream^ s;

public:
    MyWriter(Stream^ stream)
    {
        s = stream;
    }

    void WriteDouble(double myData)
    {
        array<Byte>^ b = BitConverter::GetBytes(myData);
        // GetBytes is a binary representation of a double data type.
        s->Write(b, 0, b->Length);
    }

    void Close()
    {
        s->Close();
    }
};

In this example, you create a class that has a constructor with a stream argument. From here, you can expose whatever Write methods are necessary. You must convert whatever you are writing to a byte[]. After you obtain the byte[],the Write method writes it to the stream s.
