Mix and sort files


Create a program that reads the contents of two different files, merges them, and sorts them alphabetically. For example, if the files contain: "Dog Cat and Chair Table", the program should display: "Cat Chair Dog Table".


Imports System
Imports System.IO
Imports System.Collections
Namespace Text
    Class Program
        Private Shared Sub Main(ByVal args As String())
            Console.Write("Enter name of file1: ")
            Dim nameFile1 As String = Console.ReadLine()
            Console.Write("Enter name of file2: ")
            Dim nameFile2 As String = Console.ReadLine()

            If (Not File.Exists(nameFile1)) OrElse (Not File.Exists(nameFile2)) Then
                Console.Write("File 1 or File 2 not exists")
            End If

                Dim myfile As StreamReader = File.OpenText(nameFile1)
                Dim list As ArrayList = New ArrayList()
                Dim line As String

                    line = myfile.ReadLine()
                    If line IsNot Nothing Then list.Add(line)
                Loop While line IsNot Nothing

                myfile = File.OpenText(nameFile2)
                line = ""

                    line = myfile.ReadLine()
                    If line IsNot Nothing Then list.Add(line)
                Loop While line IsNot Nothing


                For i As Integer = 0 To list.Count - 1

            Catch e As Exception
                Console.WriteLine("Error al intentar abir el fichero.")
            End Try
        End Sub
    End Class
End Namespace
