MemoryStream Class in VB.Net

Here, we will demonstrate MemoryStream class and write data into the memory stream using Write() and WriteByte() method.

Program/Source Code:

The source code to demonstrate the MemoryStream class is given below. The given program is compiled and executed successfully.

VB.Net code to demonstrate the example of MemoryStream class

'Vb.Net program to demonstrate MemoryStream class.

Imports System.IO

Module Module1
    Sub Main()
        Dim ms As MemoryStream
        Dim count As Integer = 0

        Dim byteBuff1() As Byte = {97, 98, 99}
        Dim byteBuff2() As Byte = {65, 66, 67}

        ms = New MemoryStream(50)

        ms.Write(byteBuff1, 0, 3)

        While (count < byteBuff2.Length)
            ms.WriteByte(byteBuff2(count))
            count = count + 1
        End While

        ms.Seek(0, SeekOrigin.Begin)

        Dim byteArray(ms.Length) As Byte

        count = ms.Read(byteArray, 0, byteArray.Length)

        ms.Close()

        Console.WriteLine("Data written into memory stream:")
        For Each b In byteArray

            Console.Write(Convert.ToChar(b))
        Next
        Console.WriteLine()
    End Sub
End Module

Output

Data written into memory stream:
abcABC
Press any key to continue . . .

Explanation

In the above program, we created a class module Module1 that a Main() function. The Main() method is the entry point of the program, here we created an object of MemoryStream class and write bytes using Write() and WriteByte() method then reset the read pointer to the beginning of the memory stream and then read byte array from the memory stream using Read() method and print character corresponding to each byte value by character typecasting on the console screen.
