使用 ASP.NET MVC 配置 Telerik 报告

Question

我正在关注这篇关于如何在 ASP.NET MVC 5 和 .NET 4.6.1 上配置 Telerik 报告的文章 Using HTML5 ASP.NET MVC Report Viewer in a web application then Telerik Reporting REST Web API to Web Application

我不能做的一件事是注册路由

如果我这样做，我会收到以下错误。我认为它与其他一些路线冲突，不确定它在哪里......

我尝试注释掉 MVC 路由注册，这也给出了同样的错误

//RouteConfig.RegisterRoutes(RouteTable.Routes);

A route named 'Resources' is already in the route collection. Route names must be unique. Parameter name: name

所以当我 POST 调用以下 URL 时没有注册路由，我得到了很好的回应。

但是如果我尝试根据文档验证报告，我会收到以下错误非常感谢任何帮助。

更新

路线问题已解决。删除了 WebApiConfig 初始化中的重复条目

当访问这个URLhttp://localhost:[portnumber]/api/reports/formats 以下错误仍未解决

Answer 1

如果您确定以下行不会在 Application_Start 中出现两次，则进入 bin folder of project、delete 所有 DLL 文件，因为如果您的旧 assemblies 仍然是其中的一部分，您可能仍然会得到 duplicate routes。然后 rebuild project 这将解决这个问题，

Answer 2

我在 web.config 中有这个部分，我删除了它并且效果很好

<section name="Telerik.Reporting" type="Telerik.Reporting.Configuration.ReportingConfigurationSection, Telerik.Reporting, Version=12.2.18.1129, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" allowLocation="true" allowDefinition="Everywhere" />
