我有这个:
public class PagesModel
{
public string ControllerName { get; set; }
public string ActionName { get; set; }
public int PagesCount { get; set; }
public int CurrentPage { get; set; }
public object RouteValues { get; set; }
public object HtmlAttributes { get; set; }
}
public static MvcHtmlString RenderPages(this HtmlHelper helper, PagesModel pages, bool isNextAndPrev = false)
{
//some code
var lastPageSpan = new TagBuilder("span");
var firstValueDictionary = new RouteValueDictionary(pages.RouteValues) { { "page", pages.PagesCount } };
lastPageSpan.InnerHtml = helper.ActionLink(">>", pages.ActionName, pages.ControllerName, firstValueDictionary, pages.HtmlAttributes).ToHtmlString();
return MvcHtmlString.Create(lastPageSpan.ToString());
}
它生成的链接如下所示:<span><a href="/Forums/Thread?Count=2&Keys=System.Collections.Generic.Dictionary%602%2BKeyCollection%5BSystem.String%2CSystem.Object%5D&Values=System.Collections.Generic.Dictionary%602%2BValueCollection%5BSystem.String%2CSystem.Object%5D">>></a></span>
为什么呢?我究竟做错了什么?当我在设置.innerHtml
之前设置断点时,我发现我的firstValueDictionary
看起来完全正常。发生了什么事?
更新:当我用新创建的匿名类型(RouteValueDictionary
)替换new {page = 0}
参数时,一切正常。为什么我不能使用预定义的RouteValueDictionary
?
答案 0 :(得分:4)
您正在使用ActionLink助手的错误重载。试试这样:
lastPageSpan.InnerHtml = helper.ActionLink(
">>",
pages.ActionName,
pages.ControllerName,
firstValueDictionary,
new RouteValueDictionary(pages.HtmlAttributes) // <!-- HERE!
).ToHtmlString();
以下是您使用的overload
:
public static MvcHtmlString ActionLink(
this HtmlHelper htmlHelper,
string linkText,
string actionName,
object routeValues,
object htmlAttributes
)
这是您需要使用的correct overload
:
public static MvcHtmlString ActionLink(
this HtmlHelper htmlHelper,
string linkText,
string actionName,
RouteValueDictionary routeValues,
IDictionary<string, object> htmlAttributes
)
注意区别?
