使用 Visual Studio Express 2012 for Web 和 Razor，我创建了一个选择列表：
List<SelectListItem> list = new List<SelectListItem>();
list.Add(new SelectListItem { Text = "Yes", Value = "1" });
list.Add(new SelectListItem { Text = "No", Value = "2" });
SelectList selectList = new SelectList(list, "Value", "Text", null);
Later, I want to get the text associated with a specific element in selectList. As a newbie, I'd think I could do this:
稍后，我想获取与 selectList 中的特定元素关联的文本。作为新手，我认为我可以这样做：
selectList.Items[1].Text
But that results in the message, "Cannot apply indexing with [] to an expression of type 'System.Collections.IEnumerable'"
但这会导致消息“无法将 [] 索引应用于‘System.Collections.IEnumerable’类型的表达式”
Thanks.
谢谢。
