当前上下文中不存在“电子邮件”名称（Web应用程序）

Question

我正在将我的sitefinity网站项目转换为Web应用程序。

我们有一个最初在网站上工作的用户控件，但现在我们在构建Web应用程序时出现以下错误。

“电子邮件”并不在当前环境中存在的名称（线104）

          profileManager.Provider.SuppressSecurityChecks = true; 

          SitefinityProfile userProfile = profileManager.CreateProfile(user, Guid.NewGuid(), typeof(SitefinityProfile)) as SitefinityProfile; 
          if (userProfile != null) 
          {

           Email.Send(tbxRegEmail.Text, "support.manager@*****.com", "*****", emailContent); 

           Response.Redirect("~/login?registered"); 
          } 

          RegError.Text = "An error occurred whilst registering. If problem persists please contact support.manager@*****.com"; 
         } 
        } 
       } 
      } 
      else 
      { 
       RegError.Text = "Please check all required fields have been filled and are valid."; 
      } 
     } 
    } 
} 

本来我们有项目中的不同的文件夹内的Email.cs文件，但似乎是Web应用程序无法找到此。

Answer 1

我可能会推荐一个稍微不同的解决方案来发送电子邮件。使用MailDefinition和MailMessage类创建电子邮件的正文，然后从此处使用类别EmailSender以及Sitefinity中的SMTP设置发送电子邮件。下面的示例代码：

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); 

ListDictionary正在用代码中的值替换正文中的值。如果你不需要，你可以只包含一个空字典。
