Strings store collections of characters. There are many
different functions you can use on Strings
in the VB.NET programming language. This selection of content
details the String-based
functions in this language.
Example
To start, this program demonstrates several concepts: how to
declare and initialize a String; how
to use a String literal such as "dot"; and how to concatenate
strings with the plus operator and
with the String.Concat method.
Program that uses String [VB.NET]
Module Module1
Sub Main()
Dim value As String = "dot"
value = value + "net"
Dim result As String = String.Concat(value, "perls")
Console.WriteLine(result)
End Sub
End Module
Output

Core functions. These functions and subroutines are some of the
most useful and widely used in
the VB.NET language. Having an understanding of them is
important for beginning VB.NET
developers. This knowledge will carry over to other .NET
languages as well.
EqualsFormatInsertLengthRemoveReplaceString
ConstructorSubstringToCharArray
ToString
Manipulate strings. These examples manipulate Strings and arrays
of Strings in various ways.
Strings are often stored in arrays.
String ArrayReverseString LoopMid
Upper and lower
The .NET Framework provides us with many different ways to
change the cases of characters in
Strings. With the VB.NET language, we can use these functions or
design our own, custom
functions.
ToLowerToUpperUppercase First Letter: StringToTitleCase

Split and Join
Some of the more popular String functions in the VB.NET language
include the Split and Join
methods. We provide examples in the following tutorials.

If you need to search your String for a character pattern or a
single character, these IndexOf and
LastIndexOf functions are ideal.
ContainsIndexOfIndexOfAnyLastIndexOfLastIndexOfAny
Whitespace
Some functions on the string type typically are used to handle
whitespace characters; these
functions include the Trim function and its variants TrimStart
and TrimEnd.
TrimTrimEndTrimStartNewLineLSet and RSetLTrim and RTrim
Ends and starts
Sometimes you need to see if one String ends with another
String, or if one String starts with
another String. To our relief, we can use the EndsWith and
StartsWith functions.

The ROT13 encoding algorithm is a clever method that shifts the
letters in the alphabet by 13
places in two directions based on their values. It is easily
reversed. We present a complete
implementation in the VB.NET language.
ROT13
Convert
It is often necessary to convert Strings to other types, such as
Integers. Conversely, most types
can be converted to Strings with ToString. We examine String
conversions.
CStrChar Array to StringList to StringString Array to
StringString to Integer
Select Case
A String instance can be used in a Select Case statement in the
VB.NET language. A logical
decision is made based on the String's character data.
Select Case
Summary
The String type in the VB.NET language is powerful, but also has
some limitations. In situations
where you can improve performance by mutating an existing
string, you will need to use an
alternative type such as StringBuilder.
Note: Strings in the VB.NET language cannot be changed after
they are created.
