Stream to ByteArray c# , VB.Net
Creating a byte array from a stream
Stream is the abstract base class of all streams and it Provides a generic view of a sequence of bytes. The Streams Object involve three fundamental operations such as Reading, Writing and Seeking. In some situations we may need to convert these stream to byte array. This lesson explain how to convert a stream to byteArray.
Convert byte array from stream
C# Source Code - Method 1
using System;
using System.IO;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
FileStream stream1 = File.Open("D:\\file.txt", FileMode.Open);
byte[] buff = streamToByteArray(stream1);
stream1.Close();
MessageBox.Show(Encoding.UTF8.GetString(buff, 0, buff.Length));
}
public static byte[] streamToByteArray(Stream stream)
{
byte[] byteArray = new byte[16 * 1024];
using (MemoryStream mSteram = new MemoryStream())
{
int bit;
while ((bit = stream.Read(byteArray, 0, byteArray.Length)) > 0)
{
mSteram.Write(byteArray, 0, bit);
}
return mSteram.ToArray();
}
}
}
}

{
FileStream stream1 = File.Open("D:\\file.txt", FileMode.Open);
byte[] buff = streamToByteArray(stream1);
stream1.Close();
MessageBox.Show(Encoding.UTF8.GetString(buff, 0, buff.Length));
}
public static byte[] streamToByteArray(Stream stream)
{
using (MemoryStream ms = new MemoryStream())
{
stream.CopyTo(ms);
return ms.ToArray();
}
}
}
}
Convert byte array from stream - VB.Net Source Code
Imports System.IO
Imports System.Text
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim stream1 As FileStream = File.Open("D:\file.txt", FileMode.Open)
Dim buff As Byte() = streamToByteArray(stream1)
stream1.Close()
MsgBox(Encoding.UTF8.GetString(buff, 0, buff.Length))
End Sub
Public Shared Function streamToByteArray(ByVal stream As Stream) As Byte()
Using ms As New MemoryStream()
stream.CopyTo(ms)
Return ms.ToArray()
End Using
End Function
End Class
