How to Concatenat Strings in VB.NET
In this article we use a new class StringBuilder to perform string concatenation.
We can concatenate string Vb.Net by using '&'
operator but there is a drawback of this procedure of concatenation that on
every concatenation, a string variable was created and the old one was
destroyed. So, Vb.Net provided a new class called StringBuilder to resolving the
old problem. The StringBuilder dynamically allocates the memory block to the
same object. It resides in the system.text namespace.
Here is the Example of using StringBuilder
class
Imports System.Text
Module Module1
Sub Main()
Dim concatenation As New StringBuilder()
concatenation.Append("Manish
")
concatenation.Append("is
student ")
concatenation.Append("of
")
concatenation.Append("NIIT.")
Dim myString As New String(concatenation.ToString())
Console.WriteLine(concatenation)
Console.ReadLine()
End Sub
End Module
OUTPUT

CONCLUSION
So, in this article you see two separate
objects, first is StringBuilder which take care of memory management and the
another is .toString() which is responsible for the result output production.
