ListView-绑定到简单标量数组时,是否可以设置DataKeyName?

您可以使用Linq执行此操作:

string [] files = ...;

var list = from f in files
    select new { Letter = f };

// anonymous type created with member called Letter

lv.DataKeyNames = "Letter";
lv.DataSource = list;
lv.DataBind();

尝试对对象使用常规列表。下面的例子是C#3.0。假设您想要一个字母列表:

public class LettersInfo
{
    public String Letter { get; set; }
}

然后列出一个清单:

List<LettersInfo> list = new List<LettersInfo>();
list.add(new LettersInfo{ Letter = "A" });
list.add(new LettersInfo{ Letter = "B" });
list.add(new LettersInfo{ Letter = "C" });

然后将其绑定到listview

lv.DataKeyNames = "Letter";
lv.DataSource = list;
lv.DataBind();
