问题描述

与VB.Net循环结构相当的C＃是什么：

Dim li作为ListItem

For each li in rbl.Items


下一页li

What is the C# equivalent to the VB.Net looping structure:

C# has foreach as well:

Any class that implements IEnumerable will support foreach.

Actually any class with a public GetEnumerator() method that returns an
IEnumerator implementation will support foreach. The class doesn''t need to
