VB.Net provides following types of loops to handle looping requirements.
Loop Type
|
Description
|
Do Loop
|
It repeats the enclosed block of statements while a Boolean condition
is True or until the condition becomes True. It could be terminated at any
time with the Exit Do statement.
|
For...Next
|
It repeats a group of statements a specified number of times and a
loop index counts the number of loop iterations as the loop executes.
|
For Each...Next
|
It repeats a group of statements for each element in a collection.
This loop is used for accessing and manipulating all elements in an array or
a VB.Net collection.
|
While... End
While
|
It executes a series of statements as long as a given condition is True.
|
With... End With
|
It is not exactly a looping construct. It executes a series of
statements that repeatedly refer to a single object or structure.
|
Nested loops
|
You can use one or more loops inside any another While, For or Do
loop.
