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
如果您只需要将视图呈现为字符串，请尝试以下操作：
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。
