姓名'邮箱'在当前上下文中不存在(Web应用程序)

我正在将我的sitefinity网站项目转换为web应用程序。

我们有一个用户控制，原来是在网站上工作，但现在我们得到以下错误时，构建web应用程序。

最初我们在项目的另一个文件夹中有一个Email.cs文件，但是webapp似乎找不到它

using System.Net.Mail;
using Telerik.Sitefinity.Services;
using Telerik.Sitefinity.Web.Mail;
using Telerik.Sitefinity.Configuration;
var smtpSettings = Config.Get<SystemConfig>().SmtpSettings;
MailDefinition mailDef = new MailDefinition()
{
    IsBodyHtml = true,
    BodyFileName = "~/Files/EmailBody.html",
    Subject = "Thanks for Commenting!",
    From = !smtpSettings.DefaultSenderEmailAddress.IsNullOrEmpty() ?  smtpSettings.DefaultSenderEmailAddress : smtpSettings.UserName
};
MailMessage email = mailDef.CreateMailMessage(this.EmailControl.Value.ToString(), new ListDictionary(), this);
EmailSender.Get().Send(email);
