Explanation

In the above program, we created a module Module1 that contains the Main() function. The Main() function is the entry point for the program, here, we created an array of bytes, which is initialized with some byte values.

File.WriteAllBytes("Sample.txt", buff)
Console.WriteLine("Data written successfully")

In the above code, we write multiple bytes into the "sample.txt" file and printed the "Data written successfully" message on the console screen.
