Question

我正在浏览我的应用，尝试清理一些发送电子邮件的代码。我开始创建自己的电子邮件包装器类，但后来我认为某处必须有一个标准的电子邮件类。我做了一些搜索，但找不到任何东西。

此外，是否有适用于此类内容的代码库？

编辑：抱歉，让我澄清一下。

我不想在我需要发送电子邮件时在我的代码中使用此代码：

System.Web.Mail.MailMessage message=new System.Web.Mail.MailMessage();
message.From="from e-mail";
message.To="to e-mail";
message.Subject="Message Subject";
message.Body="Message Body";
System.Web.Mail.SmtpMail.SmtpServer="SMTP Server Address";
System.Web.Mail.SmtpMail.Send(message);

我创建了一个名为Emailer的类，其中包含以下函数：

SendEmail(string to, string from, string body)
SendEmail(string to, string from, string body, bool isHtml)

所以我可以在我的代码中添加一行来发送电子邮件：

Emailer.SendEmail("name@site.com", "name2@site.com", "My e-mail", false);

我的意思是，它并不太复杂，但我认为那里有一个标准的，可接受的解决方案。

这样的东西？

using System;
using System.Net;
using System.Net.Mail;
using System.Net.Mime;
using MailMessage=System.Net.Mail.MailMessage;

class CTEmailSender
{
    string MailSmtpHost { get; set; }
    int MailSmtpPort { get; set; }
    string MailSmtpUsername { get; set; }
    string MailSmtpPassword { get; set; }
    string MailFrom { get; set; }

    public bool SendEmail(string to, string subject, string body)
    {
        MailMessage mail = new MailMessage(MailFrom, to, subject, body);
        var alternameView = AlternateView.CreateAlternateViewFromString(body, new ContentType("text/html"));
        mail.AlternateViews.Add(alternameView);

        var smtpClient = new SmtpClient(MailSmtpHost, MailSmtpPort);
        smtpClient.Credentials = new NetworkCredential(MailSmtpUsername, MailSmtpPassword);
        try
        {
            smtpClient.Send(mail);
        }
        catch (Exception e)
        {
            //Log error here
            return false;
        }

        return true;
    }
}

也许您正在寻找SmtpClient？

我使用this old Stack Overflow Answer制作的通用类试试这个。

public bool SendEmail(MailAddress toAddress, string subject, string body)
{
    MailAddress fromAddress = new MailAddress("pull from db or web.config", "pull from db or web.config");
    string fromPassword = "pull from db or config and decrypt";
    string smtpHost = "pull from db or web.config";
    int smtpPort = 587;//gmail port

    try
    {
        var smtp = new SmtpClient
        {
            Host = smtpHost,
            Port = smtpPort,
            EnableSsl = true,
            DeliveryMethod = SmtpDeliveryMethod.Network,
            UseDefaultCredentials = false,
            Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
        };
        using (var message = new MailMessage(fromAddress, toAddress)
        {
            Subject = subject,
            Body = body,
            IsBodyHtml = true
        })
        {
            smtp.Send(message);
        }
        return true;
    }
    catch (Exception err)
    {
        Elmah.ErrorSignal.FromCurrentContext().Raise(err);
        return false;
    }

}

这是我的一个项目的片段。它比其他一些实现更具功能性。

使用此功能可以创建包含以下内容的电子邮件：

可以在运行时用实际值替换的标记

包含文字和HTML视图的电子邮件

public MailMessage createMailMessage(string toAddress, string fromAddress, string subject, string template)
{
// Validate arguments here...

// If your template contains any of the following {tokens}
// they will be replaced with the values you set here.
var replacementDictionary = new ListDictionary
       {
           // Replace with your own list of values
           { "{first}", "Pull from db or config" },
           { "{last}", "Pull from db or config" }
       };

// Create a text view and HTML view (both will be in the same email)
// This snippet assumes you are using ASP.NET (works w/MVC)
//    if not, replace HostingEnvironment.MapPath with your own path.
var mailDefinition = new MailDefinition { BodyFileName = HostingEnvironment.MapPath(template + ".txt"), IsBodyHtml = false };
var htmlMailDefinition = new MailDefinition { BodyFileName = HostingEnvironment.MapPath(template + ".htm"), IsBodyHtml = true };

MailMessage htmlMessage = htmlMailDefinition.CreateMailMessage(email, replacementDictionary, new Control());
MailMessage textMessage = mailDefinition.CreateMailMessage(email, replacementDictionary, new Control());

AlternateView plainView = AlternateView.CreateAlternateViewFromString(textMessage.Body, null, "text/plain");
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(htmlMessage.Body, null, "text/html");

var message = new MailMessage { From = new MailAddress(from) };

message.To.Add(new MailAddress(toAddress));
message.Subject = subject;

message.AlternateViews.Add(plainView);
message.AlternateViews.Add(htmlView);

return message;
}

假设你已经为NetMail设置了Web.config，你可以通过这样的辅助方法调用这个方法：

public bool SendEmail(MailMessage email)
{
    var client = new SmtpClient();

    try
    {
       client.Send(message);
    }
    catch (Exception e)
    {
        return false;
    }

    return true;
}

SendMail(createMailMessage("to@email.com", "from@email.com", "Subject", "~/Path/Template"));

标准的电子邮件类？
