Visual Basic Each…Next 循环

Each…Next 为集合中的每个元素重复执行一组语句，可简单理解为遍历数组元素。此循环用于访问和操作数组或 VB 集合中的所有元素。

这个循环结构的语法是:

For Each element [ As datatype ] In group
    [ statements ]
    [ Continue For ]
    [ statements ]
    [ Exit For ]
    [ statements ]
Next [ element ]

实例

Module loops
  Sub Main()
   Dim anArray() As Integer = {1, 3, 5, 7, 9}
   Dim arrayItem As Integer
   'displaying the values
   For Each arrayItem In anArray
     Console.WriteLine(arrayItem)
   Next
   Console.ReadLine()
  End Sub
End Module

结果如下:

1
3
5
7
9
