Public Class ConcatTest Public Shared Sub Main() Dim fName As String = "Simon" Dim mName As String = "Jake" Dim lName As String = "Harrows" ' We want to simply quickly add this person's name together. ' Because we want a name to appear with a space in between each name, ' we put a space on the front of the middle, and last name, allowing for ' the fact that a space may already be there. mName = " " + mName.Trim() lName = " " + lName.Trim() ' This line simply concatenates the two strings. Console.WriteLine("Welcome to this page, '{0}'!", _ String.Concat(String.Concat(fName, mName), lName)) End Sub End Class ' The example displays the following output: ' Welcome to this page, 'Simon Jake Harrows'!
