C# SelectNode始终选择可枚举中的第一个节点<；HtmlNode>；迭代时
我试图从多个htmlnodes集合中解析多个键，我会使用selectnodes->div[@class=“key”]来完成这项工作，但出于某种原因，这总是选择所有键，但我希望这些键采用列表格式，其中列表索引引用行索引，在这之后，我尝试选择一个节点，但从逻辑上讲，这总是选择“esc”键，因为这是第一行/索引，你知道我如何将它们分开吗 DirtyFix：C# SelectNode始终选择可枚举中的第一个节点<；HtmlNode>；迭代时,c#,html-agility-pack,C#,Html Agility Pack,我试图从多个htmlnodes集合中解析多个键，我会使用selectnodes->div[@class=“key”]来完成这项工作，但出于某种原因，这总是选择所有键，但我希望这些键采用列表格式，其中列表索引引用行索引，在这之后，我尝试选择一个节点，但从逻辑上讲，这总是选择“esc”键，因为这是第一行/索引，你知道我如何将它们分开吗 DirtyFix： var page = browser.Load(layout_link); var key_row
