asp.net-mvc – 可以使用ASP.Net MVC Razor视图来生成格式很好的HTML Body作为从服务器

我想利用Razor View的模型绑定/渲染功能来生成我从ASP.NET MVC应用程序发送的电子邮件的HTML正文内容。

有没有办法将视图呈现为字符串，而不是将其作为GET请求的ActionResult返回？

为了说明我正在寻找将会做以下事情的东西：

public ActionResult SendEmail(int id)
    {
        EmailDetailsViewModel emailDetails = EmailDetailsViewModel().CreateEmailDetails(id);

        // THIS IS WHERE I NEED HELP...
        // I want to pass my ViewModel (emailDetails) to my View (EmailBodyRazorView) but instead of Rending that to the Response stream I want to capture the output and pass it to an email client.
        string htmlEmailBody = View("EmailBodyRazorView",emailDetails).ToString();

        // Once I have the htmlEmail body I'm good to go.  I've got a utilityt that will send the email for me.
        MyEmailUtility.SmtpSendEmail("stevejobs@apple.com","Email Subject",htmlEmailBody);

        // Redirect another Action that will return a page to the user confirming the email was sent.
        return RedirectToAction("ConfirmationEmailWasSent");
    }

解决方法

public string ToHtml(string viewToRender,ViewDataDictionary viewData,ControllerContext controllerContext)
{
    var result = ViewEngines.Engines.FindView(controllerContext,viewToRender,null);

    StringWriter output;
    using (output = new StringWriter())
    {
        var viewContext = new ViewContext(controllerContext,result.View,viewData,controllerContext.Controller.TempData,output);
        result.View.Render(viewContext,output);
        result.ViewEngine.ReleaseView(controllerContext,result.View);
    }

    return output.ToString();
}

您需要从控制器操作中传递视图的名称以及ViewData和ControllerContext。
