以编程方式呈现 ServiceStack Razor 视图

Question

我正在尝试在服务器上以编程方式呈现 ServiceStack Razor 页面（因此我可以通过电子邮件发送它）。我正在关注https://groups.google.com/forum/#!topic/servicestack/RqMnfM73ic0 帖子上的信息，但是当我使用 cshtml 文件的有效路径调用“AddPage”方法时，它会失败。

var response = svc.Get(oReq);

        var razor = TryResolve<RazorFormat>();
        var path = @"C:\GetOrderResponse.cshtml";
        var razorPage = razor.AddPage(path);

这会引发参数异常并显示以下消息：

第二个路径片段不能是驱动器或 UNC 名称。 参数名称：path2

 at System.IO.FileSystemEnumerableIterator`1.GetFullSearchString(String fullPath, String        searchPattern)
  at System.IO.FileSystemEnumerableIterator`1..ctor(String path, String originalUserPath, String searchPattern, SearchOption searchOption, SearchResultHandler`1 resultHandler, Boolean checkHost)

如果它在/Views/ 下，您可能不想添加应该已经添加的页面。相反，您可以按名称解析现有页面并将其呈现为 html：

var razor = HostContext.GetPlugin<RazorFormat>();
var orderPage = razor.GetViewPage("GetOrderResponse");
email.BodyHtml = razor.RenderToHtml(orderPage, order);
