Write Byte Array to a text file

The following VB.NET program shows how to write the content of a Byte Array into a Text file.

Byte is an immutable value type that represents unsigned integers with values that range from 0 to 255 . Here we open a FileStream class instance and using the method Write() . Write() method writes a block of bytes to the current stream using data read from buffer.

  oFileStream.Write(byteData, 0, byteData.Length)



Public Class Form1

	Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

		Dim str As String = "http://vb.net-informations.com"
		Dim encod As New System.Text.UTF8Encoding
		Dim byteData() As Byte = encod.GetBytes(str)

		Dim oFileStream As System.IO.FileStream
		oFileStream = New System.IO.FileStream("c:\bytes.txt", System.IO.FileMode.Create)
		oFileStream.Write(byteData, 0, byteData.Length)
		oFileStream.Close()

	End Sub
End Class
