c# - RouteValueDictionary 和 htmlAttributes 之间是否存在冲突？

Question

我正在使用 RouteValueDictionary 将 RouteValues 传递给 ActionLink:

如果我编码:

<%:Html.ActionLink(SharedResources.Shared_Pagination_First, Model.ActionToExecute, Model.ControllerToExecute, Model.FirstRouteValues, null)%>

链接结果正常:

SearchArticles?refSearch=2&exact=False&manufacturerId=5&modelId=3485&engineId=-1&vehicleTypeId=5313&familyId=100032&page=0

但是如果我编码:

<%: Html.ActionLink(SharedResources.Shared_Pagination_First, Model.ActionToExecute, Model.ControllerToExecute, Model.FirstRouteValues, new { @title = string.Format(SharedResources.Shared_Pagination_LinkTitle, 0) })%>

链接结果为:

SearchArticles?Count=10&Keys=System.Collections.Generic.Dictionary%602%2BKeyCollection%5BSystem.String%2CSystem.Object%5D&Values=System.Collections.Generic.Dictionary%602%2BValueCollection%5BSystem.String%2CSystem.Object%5D

有什么问题？唯一的区别是，最后我使用的是 htmlAttributes

Answer 1

您使用了错误的 ActionLink 助手重载。没有需要 routeValues 的过载作为RouteValueDictionary和 htmlAttributes作为匿名对象。所以如果Model.FirstRouteValues是 RouteValueDictionary那么最后一个参数也必须是 RouteValueDictionary或者一个简单的 IDictionary<string,object>而不是匿名对象。就这样:

<%= Html.ActionLink(
    SharedResources.Shared_Pagination_First, 
    Model.ActionToExecute, 
    Model.ControllerToExecute, 
    Model.FirstRouteValues, 
    new RouteValueDictionary(
        new { 
            title = string.Format(SharedResources.Shared_Pagination_LinkTitle, 0) 
        }
    )
) %>

或

<%=Html.ActionLink(
SharedResources.Shared_Pagination_First, 
Model.ActionToExecute, 
Model.ControllerToExecute, 
Model.FirstRouteValues, 
new Dictionary<string, object> { { "title", somevalue  } })%>
