Working with Data Structures in VB.NET String

In VB.NET, string is a very powerful data type that is used to store and manipulate text data. In this page, we will discuss the various data structures that you can use to work with strings in VB.NET.

Syntax

There are various data structures that you can use to work with strings in VB.NET. Some of the commonly used data structures are:

1. String Function

Dim str As String = "Hello, World!"
Dim strLength As Integer
strLength = str.Length

2. String Array

Dim stringArray As String() = {"Hello", "World", "!"}

3. String Methods

Dim str As String = "Hello, World!"
Dim firstChar As Char = str.First()
Dim lastChar As Char = str.Last()
Dim subStr As String = str.Substring(7, 5)

Example

Here's an example of working with data structures in VB.NET string:

Module Module1

    Sub Main()
        ' Example of String Function
        Dim str As String = "Hello, World!"
        Dim strLength As Integer
        strLength = str.Length
        Console.WriteLine("String Length: " & strLength)

        ' Example of String Array
        Dim stringArray As String() = {"Hello", "World", "!"}
        Console.WriteLine("String Array: ")
        For Each str In stringArray
            Console.Write(str & " ")
        Next

        ' Example of String Methods
        Dim str2 As String = "Hello, World!"
        Dim firstChar As Char = str2.First()
        Dim lastChar As Char = str2.Last()
        Dim subStr As String = str2.Substring(7, 5)
        Console.WriteLine(vbCrLf & "First Character: " & firstChar)
        Console.WriteLine("Last Character: " & lastChar)
        Console.WriteLine("Substring: " & subStr)
    End Sub

End Module

Output

The output of the above code will be:

String Length: 13
String Array:
Hello World !
First Character: H
Last Character: !
Substring: World

Explanation

In the above example, we first declared a string variable str and measured its length using the Length function. Then we created a string array stringArray and used a For Each loop to print each element of the array. Finally, we used some string methods like First(), Last(), and Substring() to manipulate a string.

Use

Working with data structures in VB.NET string is useful when you need to manipulate text data in various ways. For example, you can split a string into an array of substrings using the Split() method, or you can concatenate multiple strings using the & operator.

Important Points

  • String data type is a powerful data type in VB.NET that is used to store and manipulate text data.
  • There are various data structures that you can use to work with strings in VB.NET including string functions, string arrays, and string methods.
  • Working with data structures in VB.NET string is useful when you need to manipulate text data in various ways.
