将Razor View渲染为ASP.NET Core中的字符串 [英] Render Razor View to string in ASP.NET Core
问题描述
我使用 RazorEngine 来解析我的MVC 6项目中的模板，如下所示:
I use RazorEngine for parsing of templates in my MVC 6 project like this:
Engine.Razor.RunCompile(File.ReadAllText(fullTemplateFilePath), templateName, null, model);
它对于beta 6正常工作.在升级到beta 7并出现以下错误后，它将无法正常工作:
It works fine for the beta 6. It does not work after upgrading to beta 7 with the error:
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)
MissingMethodException: Method not found: "Void Microsoft.AspNet.Razor.CodeGenerators.GeneratedClassContext.set_ResolveUrlMethodName(System.String)". in RazorEngine.Compilation.CompilerServiceBase.CreateHost(Type templateType, Type modelType, String className)
这是global.json:
This is global.json:
{
"projects": [ "src", "test" ],
"sdk": {
"version": "1.0.0-beta7",
"runtime": "clr",
"architecture": "x64"
}
}
这是project.json:
This is project.json:
...
"dependencies": {
"EntityFramework.SqlServer": "7.0.0-beta7",
"EntityFramework.Commands": "7.0.0-beta7",
"Microsoft.AspNet.Mvc": "6.0.0-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?
Does anyone have similar problems? There is another way to parse templates in MVC 6?

UPDATE 2016年7月
在以下版本1.0.0，RC2
以aspnetcore RC2为目标的代码段可能会帮助您:
Who's targeting aspnetcore RC2, this snippet might help you:
- 创建一个单独的服务，因此，如果您不在控制器上下文中，则可以使用它，例如从命令行或在队列运行器上等...
- 在您的IoC容器中的
Startup类 中注册此服务.
- Create a separate Service, so you can use it either if you are not in a controller context, e.g. from a command line or on a queue runner, etc ...
- Register this service in your IoC container in the
Startupclass

// 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);
注释
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.
Notes
Links in Razor are rendered as relative URL, so this will not work on external views (like emails, etc ...).
目前，正在控制器上生成链接，并将其通过ViewModel传递给视图.
As for now am generating the link on the controller and pass it to the view through the ViewModel.
