MailMessage.IsBodyHtml做什么？ [英] What does MailMessage.IsBodyHtml do?

问题描述

我正在测试通过C＃发送一些电子邮件，但是我无法确定什么效果设置 IsBodyHtml 到 true 有。不管价值如何，无论我在Body中发送的内容类型为text / plain，我的HTML都显示了我的电子邮件客户端（gmail）中的所有标签。这个标志实际上应该做什么？

注意：我可以通过创建一个 AlternateView 内容类型为text / html，我只是想了解如何设置身体应该工作。

解决方案

这是我每天使用的SMTP帮助器的摘录....

  public bool SendMail（string strTo，string strFrom， string strCc，string strBcc，string strBody，string strSubject）
 {
 
 bool isComplete = true; 
 
 SmtpClient smtpClient = new SmtpClient（）; 
 MailMessage message = new MailMessage（）; 
 
 try 
 {
 //默认端口将为25 
 smtpClient.Port = 25; 
 
 message.From = new MailAddress（smtpEmailSource）; 
 message.To.Add（strTo）; 
 message.Subject = strSubject; 
 
 if（strCc！=）{message.Bcc.Add（new MailAddress（strCc））; } 
 if（strBcc！=）{message.Bcc.Add（new MailAddress（strBcc））; } 
 
 message.IsBodyHtml = true; 
 
 string html = strBody; //我通常用标签的HTML文件（例如{firstName}）替换为内容。这允许我通过打开.HTML文件来编辑VS中的电子邮件，并且很容易进行字符串替换。 
 
 AlternateView htmlView = AlternateView.CreateAlternateViewFromString（html，new ContentType（text / html））; 
 
 message.AlternateViews.Add（htmlView）; 
 
 
 //发送SMTP邮件
 smtpClient.Send（message）; 
} 
 catch 
 {
 isComplete = false; 
} 
 
 return isComplete; 
}

我最初离开的关键点...

1. IsBodyHtml声明您的消息是HTML格式的。如果你只发送一个HTML视图，这就是你需要的。




2. AlternateView用于存储我的HTML，这不是发送HTML消息，但如果要发送包含HTML和纯文本的消息，如果接收方无法呈现HTML，则需要。

我拿出了我的plainView，所以这并不明显，对不起...

这里的关键是，如果你想发送HTML格式的消息，您需要使用IsBodyHtml = true（默认为false）将您的内容呈现为HTML。

I'm testing sending out some emails via C#, but I can't tell what effect setting IsBodyHtml to true has. Regardless of the value, whatever I send in my Body shows up with a content type of "text/plain", and my HTML shows up tags and all in my email client (gmail). What is that flag actually supposed to do?

NOTE: I can send an HTML email just fine by creating an AlternateView with a content type of "text/html", I just want to understand how setting the body is supposed to work.

解决方案

Here is an excerpt for my SMTP helper I use everyday....

public bool SendMail(string strTo, string strFrom, string strCc, string strBcc, string strBody, string strSubject)
{

    bool isComplete = true;

    SmtpClient smtpClient = new SmtpClient();
    MailMessage message = new MailMessage();

    try
    {
        //Default port will be 25
        smtpClient.Port = 25;

        message.From = new MailAddress(smtpEmailSource);
        message.To.Add(strTo);
        message.Subject = strSubject;

        if (strCc != "") { message.Bcc.Add(new MailAddress(strCc)); }
        if (strBcc != "") { message.Bcc.Add(new MailAddress(strBcc)); }

        message.IsBodyHtml = true;

        string html = strBody;  //I usually use .HTML files with tags (e.g. {firstName}) I replace with content.  This allows me to edit the emails in VS by opening a .HTML file and it's easy to do string replacements.

        AlternateView htmlView = AlternateView.CreateAlternateViewFromString(html, new ContentType("text/html"));

        message.AlternateViews.Add(htmlView);


        // Send SMTP mail
        smtpClient.Send(message);
    }
    catch
    {
        isComplete = false;
    }

    return isComplete;
}

[UPDATE]

The key points as I originally left off...

1. IsBodyHtml states that your message is HTML formatted. If you were only sending a single view of HTML, this is all you need.

2. AlternateView is used to store my HTML, this is not required for sending a HTML message but it's required if you want to send a message that includes HTML and Plain Text, in case the receiver is unable to render the HTML.

I took out my plainView above so this isn't obvious, sorry...

The key here is that if you want to send a HTML formatted message you need to use IsBodyHtml = true (default is false) to have your content rendered as HTML.
