将Razor View渲染为ASP.NET Core中的字符串

c#

我使用RazorEngine解析MVC 6项目中的模板,如下所示:

Engine.Razor.RunCompile(File.ReadAllText(fullTemplateFilePath), templateName, null, model);

对于beta 6来说,它可以正常工作。在升级到beta 7并出现以下错误后,它无法工作:

MissingMethodException:找不到方法:“无效Microsoft.AspNet.Razor.CodeGenerators.GeneratedClassContext.set_ResolveUrlMethodName(System.String)”。在RazorEngine.Compilation.CompilerServiceBase.CreateHost(Type
templateType,type modelType,String className)中

这是global.json:

{
  "projects": [ "src", "test" ],
  "sdk": {
    "version": "1.0.0-beta7",
    "runtime": "clr",
    "architecture": "x64"
  }
}

这是project.json:

...
"dependencies": {
    "EntityFramework.SqlServer": "7.0.0-beta7",
    "EntityFramework.Commands": "7.0.0-beta7",
    "Microsoft.AspNet.Mvc": "6.0.0-beta7",
    "Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-beta7",
    "Microsoft.AspNet.Authentication.Cookies": "1.0.0-beta7",
    "Microsoft.AspNet.Authentication.Facebook": "1.0.0-beta7",
    "Microsoft.AspNet.Authentication.Google": "1.0.0-beta7",
    "Microsoft.AspNet.Authentication.MicrosoftAccount": "1.0.0-beta7",
    "Microsoft.AspNet.Authentication.Twitter": "1.0.0-beta7",
    "Microsoft.AspNet.Diagnostics": "1.0.0-beta7",
    "Microsoft.AspNet.Diagnostics.Entity": "7.0.0-beta7",
    "Microsoft.AspNet.Identity.EntityFramework": "3.0.0-beta7",
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta7",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-beta7",
    "Microsoft.AspNet.StaticFiles": "1.0.0-beta7",
    "Microsoft.AspNet.Tooling.Razor": "1.0.0-beta7",
    "Microsoft.Framework.Configuration.Abstractions": "1.0.0-beta7",
    "Microsoft.Framework.Configuration.Json": "1.0.0-beta7",
    "Microsoft.Framework.Configuration.UserSecrets": "1.0.0-beta7",
    "Microsoft.Framework.Logging": "1.0.0-beta7",
    "Microsoft.Framework.Logging.Console": "1.0.0-beta7",
    "Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.0.0-beta7",
    "RazorEngine": "4.2.2-beta1"
  },
...
  "frameworks": {
    "dnx451": { }
  },
...

我的模板是:

@model dynamic

@{

    Layout = null;

}



<!DOCTYPE html>



<html lang="en" xmlns="http://www.w3.org/1999/xhtml">

<head>

    <meta charset="utf-8" />

    <title>Registration</title>

</head>

<body>

<p>

    Hello, @Model

</p>

</body>

</html>

有人有类似的问题吗?在MVC 6中还有另一种解析模板的方法吗?

在以下版本上工作正常1.0.0RC2


谁针对aspnetcore RC2,此代码段可能会帮助您:

  • 创建一个单独的服务,因此,如果您不在控制器环境中(例如,从命令行或在队列运行器上),则可以使用它…
  • Startup课程的 IoC容器中注册此服务

用法

// using a Model
string html = view.Render("Emails/Test", new Product("Apple"));

// using a Dictionary<string, object>
var viewData = new Dictionary<string, object>();
viewData["Name"] = "123456";

string html = view.Render("Emails/Test", viewData);

笔记

Razor中的链接显示为 相对 URL,因此在外部视图(例如电子邮件等)上将不起作用。

至于现在正在控制器上生成链接,并将其通过ViewModel传递给视图。
