迴圈槽列表中的專案

Created: November-22, 2018

Dim aList as New List(Of String)
aList.Add("one")
aList.Add("two")
aList.Add("three")

For Each str As String in aList
    System.Console.WriteLine(str)
Next

產生以下輸出：

one
two
three

另一種選擇是使用每個元素的索引進行迴圈：

Dim aList as New List(Of String)
aList.Add("one")
aList.Add("two")
aList.Add("three")

For i = 0 to aList.Count - 1 'We use "- 1" because a list uses 0 based indexing.
    System.Console.WriteLine(aList(i))
Next
