Write Byte Array to a text file

A byte is a value type in programming that is immutable, meaning it cannot be changed once it is assigned a value. In the context of computer science, a byte represents an unsigned integer, which is a whole number that ranges from 0 to 255. This range allows a byte to store a wide variety of numerical values.

Byte Array to a text file

To accomplish a specific task in VB.NET, we initiate the process by opening an instance of the FileStream class. This class provides functionality for reading from and writing to files in a low-level manner. By creating an instance of this class, we gain access to the necessary methods and properties to manipulate file streams.

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

One of the methods available to us is the Write() method. This method serves the purpose of writing a block of bytes to the current stream, utilizing the data obtained from a designated buffer. In this particular scenario, we utilize the Write() method to write the contents of our byte array to the current stream, which represents the text file we are working with.
