当发送电子邮件时，如何插入包含样式的整个HTML文件？
当发送电子邮件时，如何插入包含样式的整个HTML文件？
我想发送一封电子邮件。我有一个HTML模板，想用它来发送邮件。我会从文本框中传递一些数据，就像在系统上注册后收到的确认电子邮件中包含您的详细信息一样。我无法插入或添加格式，因为它会出现错误。
以下是我的代码：
public void SendingEmails()
{
string emailbody = string.Empty;
string mapfile = HttpContext.Current.Server.MapPath("~/EmailTemplate.htm");
using (StreamReader reader = new StreamReader(mapfile))
{
if (reader == null)
{
throw new Exception("文件为空");
}
emailbody = reader.ReadToEnd();
}
emailbody = emailbody.Replace("{Url}", _Url);
string Username = "********";
string Password = "********";
string host = "********";
string FromEmailAddress = "********";
string ToEmailAddress = "********";
string emailBody = string.Empty;
var _mail = new MailMessage();
{
SmtpClient smtp = new SmtpClient();
smtp.Port = 25;
smtp.EnableSsl = false;
smtp.Host = host;
smtp.Timeout = 8900000;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new System.Net.NetworkCredential(Username, Password);
_mail.From = new MailAddress(FromEmailAddress);
_mail.To.Add(ToEmailAddress);
_mail.Subject = "电子邮件确认";
eBody = emailBody.ToString();
_mail.IsBodyHtml = true;
smtp.Send(_mail);
}
}
问题出现的原因是HTML代码中存在多行，并且HTML代码中有双引号。可以通过使用@作为多行字符串格式化器，并将HTML中的所有双引号更改为单引号'来解决问题。或者，如果仍然需要在HTML中使用双引号，则可以通过使用反斜杠\"来转义其含义。
以下是清理过的代码，请将其复制粘贴到您的代码中使用：
string emailBody = @"<div class='WordSection1'>

谢谢您的帮助。发送的邮件只有主题而没有内容。
问题的原因是想要在发送邮件时插入带有样式的整个HTML文件。解决方法是先将HTML代码中的所有换行符去除，并将其放入一行中。然后，在字符串中的每个引号前面加上反斜杠，以避免编译器认为字符串已结束。最后，可以使用字符串格式化的方法将其他变量包含在HTML字符串中。建议使用字符串插值。
这是一团乱麻。
首先，你需要去除HTML代码中的所有换行符，并将其放在一行中。
然后，你需要在字符串中的每个引号前面加上反斜杠，以避免编译器认为字符串已结束。这将停止编译器认为你已经结束了字符串。
例如：
var escapedString = "The woman said: \"Hello, young man.\"";
然后，你需要使用某种字符串格式化的方法来包含HTML字符串中的所有其他变量。（我建议使用字符串插值）
