Imports System.IO

Module Module1
    Class Sample
        Shared str As String = "This is a cat.
This is dog.
This is elephant."

        Shared Sub ReadLines()
            Dim line As String

            Dim flag As Boolean = True
            Dim strReader As New StringReader(str)

            While (flag = True)
                line = strReader.ReadLine()
                If line = Nothing Then
                    flag = False
                Else
                    line_num = line_num + 1
                    Console.WriteLine("Line {0} : {1}", line_num, line)
                End If
            End While
        End Sub
    End Class

    Sub Main()
        Sample.ReadLines()
    End Sub
End Module

Output

Line 1 : This is a cat.
Line 2 : This is dog.
Line 3 : This is elephant.

Explanation

In the above program, we created a class module Module1 that contains a class Sample and a Main() function. The Sample class contains a data member str that contains multiple lines of data. It also contains a shared method ReadLine().

In the ReadLines() method, we read the data line by line from data member str using the ReadLine() method of StringReader class and print on the console screen.

The Main() method is the entry point of the program, here we called the shared method ReadLines().
