Delete Selected Arraylist Item

[Cherel]

Hi all, I would like to know how do I do the code if I wanna delete a selected item from the array list and not all the items store in the array list? My code is,

Dim PageObject As pageItem
        PageObject = New pageItem("Page" + pnumber.ToString)
        PageObject.itemFile = OpenFileDialog1.FileName
        PageObject.videos = New ArrayList
        PageObject.podcasts = New ArrayList
        PageObject.photos = New ArrayList
        PageArray.Add(PageObject)

Thanks!
