C# 循环限制为 50 遍

Question

如何将下面的循环限制为 50，使其在到达第 51 项时停止？

foreach (ListViewItem lvi in listView.Items)
{

}

谢谢

Answer 1

使用 Linq 很容易

foreach (ListViewItem lvi in listView.Items.Take(50)) {

}

来自 MSDN 文档:

Take<(Of <(TSource>)>) enumerates source and yields elements until count elements have been yielded or source contains no more elements.

If count is less than or equal to zero, source is not enumerated and an empty IEnumerable<(Of <(T>)>) is returned.
