C# how to display images from an imagelist in a sequential order.

I am editing my previously posted question for clarity. I am trying to write a code where a new image is displayed every two seconds. I have written a code that randomly takes images from an imagelist and displays them. However, I need it to be in a sequential order. What is the best way to do this?

Ps. as you can probably tell, I am new to this site so I apologize for any formatting errors.

What I have tried:

C#

private void timer1_Tick(object sender, EventArgs e)
        {
            Random mySchool;
            mySchool = new Random();  
            picCompanies.Image = this.imageList1.Images[mySchool.Next(4)]; 
        }

P.S. Don't do Random like that -- it won't do what you want -- better to make it a static member of the class and instantiate it only once.

You do it in the same way as with a random number, only now you use your 'own' number that is incremented each time it is used (there has to be at least 1 image in the list or you have to add more error checking):

C#

private int myNumber = 0;

private void timer1_Tick(object sender, EventArgs e)
{
    picCompanies.Image = this.imageList1.Images[myNumber];
    myNumber = myNumber + 1;
    if (myNumber >= imageList1.Images.Count) myNumber = 0;
}

Or
myNumber = ( myNumber + 1 ) % imageList1.Images.Count

Nice! But probably a little too complicated given the level of this question.
