Question

我有一个ASP.NET MVC应用程序，我使用System.Net.Mail类发送电子邮件。

SmtpClient client = new SmtpClient(AppConstants.SmptHostName);
client.Credentials = new NetworkCredential(AppConstants.SmptUsername, AppConstants.SmptPassword);
MailAddress from = new MailAddress(emailSettings.AdminEmailAddress, emailSettings.EmailSender);
MailAddress to = new MailAddress(emailSettings.ApplicationEmailAddress);
MailMessage message = new MailMessage(from, to);
message.Body = GetApplicationEmail();
message.Subject = "New Application";
client.Send(message);

我正在构建要由其他应用程序导入的电子邮件，格式为：

String.Format("{0}:{1}{2}", "FieldName", "FieldValue", Environment.NewLine);

private string GetApplicationEmail()
    {
            string messageContents = "";
            var fieldList = _fieldList;

            foreach (var field in fieldList)
            {
                messageContents += String.Format("{0}:{1}{2}", field.Name, field.Value, Environment.NewLine);
            }

            return messageContents;
     }

电子邮件将如下所示：

Field1:Value1
Field2:Value2
Field3:Value3

特殊字符特别是我的问题出现了。例如正斜杠/或符号@在值中。而不是每个字段：值组合在单独的行上，它们在1行上。例如

Field1:Value1
Field2:Value2
Field3:Different/Value Field4:Extra / LongValue Field5:PeanutsAreGood
Field6:Another Value

电子邮件将作为“纯文本”发送。我不能对特殊字符进行编码，也不能转义正斜杠等字符。

我目前唯一的解决方案是用空格替换字符，但这会破坏功能。还有其他解决方案吗？

你能做这样的事吗？

 class Program
  {
    static void Main(string[] args)
    {
      SmtpClient client = new SmtpClient("smtp.gmail.com");
      client.EnableSsl = true;
      client.Port = 587;
      client.Credentials = new NetworkCredential("someEmail", "somePass");
      MailAddress from = new MailAddress("from", "Name");
      MailAddress to = new MailAddress("toEmail");
      MailMessage message = new MailMessage(from, to);

      string fieldName = @"$%^^TheField";
      string fieldValue = @"the test value)(/%";
      string string1 = String.Format("{0}:{1}{2}", fieldName, fieldValue, Environment.NewLine);

      string fieldName2 = @"anotheremail@mail.com/\";
      string fieldValue2 = @"\#the test value2";
      string string2 = String.Format("{0}:{1}{2}", fieldName2, fieldValue2, Environment.NewLine);

      List<string> messageBody = new List<string>();
      messageBody.Add(string1);
      messageBody.Add(string2);

      foreach (string str in messageBody)
      {
        message.Body += str;
      }

      message.Subject = "New Application";
      client.Send(message);

      //NonStaticClass cls = new NonStaticClass();
      //cls.GetVariable();
    }

特殊字符，例如。 @ /防止线路中断工作在电子邮件中
