In the code above, if the value of the CurrentStudent is Daniel, then we exit the ForEach completely. If it was a While we would put Exit While. You have to name what you want to Exit after the keyword, here we want to Exit the for loop only, that’s why we will put Exit For. It can seem a bit complicated so here is our real example to illustrate better.ĭim TableOfStudents = New String() ĭim OutputString As String = String.Emptyįor Each CurrentStudent As String In TableOfStudents 'Code to execute for the number of times specified A simple example would be going through a table or a list while keeping in mind where you are in this table/list.įor (Index to count on at the first position) To (Target maximum number) Step (A count speed) The For loop has been used for a long time and is, in my opinion, one of the most versatile of them all. We are in luck! Visual Basic and C# implements all of them! For (the classic loop) There are many types of loops, but the most common are For, While and Foreach. It’s a special block of code that gets executed while, until or for a certain amount of times according to a (or multiple) condition(S).

Our usual definition part! What is a loop? Sometimes you will want to execute one part of your code multiple times. But we already have and this should make loops easier! I think it might have a link with the fact that they learn debugging too late. The loops is a subject often hard to understand by new programmers.
