如何在HtmlHelper.GenerateLink方法中生成HtmlAttributes

在Controller中使用HtmlHelper.GenerateLink方法，生成一段HtmlAttributes,例如：

                    string opLink = HtmlHelper.GenerateLink(requestContext, System.Web.Routing.RouteTable.Routes,
                        "订单进程", "Default", "Create", "OrderProcess",
                        new System.Web.Routing.RouteValueDictionary(new { id = Id }), new { target = "_blank" });

我们如果在前端View页面中调用@Html.ActionLink通常会用：

new { target = "_blank" }

匿名方法来生成这段HtmlAttributes，但是如果在Controller中使用GenerateLink方法，会如下错误：

Error 1 The best overloaded method match for 'System.Web.Mvc.HtmlHelper.GenerateLink(System.Web.Routing.RequestContext, System.Web.Routing.RouteCollection, string, string, string, string, System.Web.Routing.RouteValueDictionary, System.Collections.Generic.IDictionary<string,object>)' has some invalid arguments C:\Users\...

 

Error 2 Argument 8: cannot convert from 'AnonymousType#1' to 'System.Collections.Generic.IDictionary<string,object>' C:\Users\...

MVC有一个叫做AnonymousObjectToHtmlAttributes 方法，匿名对象转换为HtmlAttributes，把上面的代码改为：

HtmlHelper.AnonymousObjectToHtmlAttributes 方法

在指定的 HTML 特性中，将下划线字符 (_) 替换为连字符 (-)。

                    string opLink = HtmlHelper.GenerateLink(requestContext, System.Web.Routing.RouteTable.Routes,
                        "订单进程", "Default", "Create", "OrderProcess",
                        new System.Web.Routing.RouteValueDictionary(new { id = Id }), HtmlHelper.AnonymousObjectToHtmlAttributes(new { target = "_blank" }));

这样就解决了。
