The For Each Loop is a iterative loop. Whenever you want to repeat a task in programming several time or a given condition in this situation we use loop statements to achieve your desired results. This article defines the For Each loop that how it repeat a task several time like For Next loop, While loop.

For Each loop

For loop is a iterative loop. it is used to execute a single item and item in group like every single element in an Array, or every single files in a folder or , every character in a String.

Example

If we want to display every character in the web site name "http://codenstuff.com" . In that situation for loop is very useful.

Code: Select all

Module Module1
    Sub Main()
        Dim Name As String
        Dim sinChar As Char
        Name = "http://codenstuff.com" 'Assigning the site name in a variable
        For Each sinChar In Name           'This line is extracting the single item from the group  
            Console.WriteLine(sinChar)
        Next
 
    End Sub
 
End Module

Now you execute this program you will get each character of the string in console window.


For Each loop with array

For Each loop is also used to work with array elements. the below example defines how to sort the array elements with for each loop.

For example

This example describes that how to sort the array elements.

Code: Select all

Module Module1
    Sub Main()
        Dim num As Integer() = New Integer(4) {}
        Console.WriteLine("Enter {0} number : ", num.Length)
        For i As Integer = 0 To num.Length - 1
            num(i) = Integer.Parse(Console.ReadLine())
        Next
        Array.Sort(num)
      Console.WriteLine("sorted array is :")
        For Each n As Integer In num
            Console.WriteLine(n)
        Next
    End Sub
 
End Module

Why don't people give credits to the person from whom he took the article/source? I hate it... Yesterday we were having a similar situation with CoderBoy.

Yes I had been writing tuts but then i lost interest in writing tuts, became tired of writing as i was not getting an idea of what to write, so i copied it.
