[英]Email subject problem
I am using MailMessage class in my program. 我在程序中使用MailMessage类。 When the subject is too long subject will look like.
当主题太长时,主题看起来像。
Subject: 学科:
=?utf-8?B?W0VudGVycHJpc2UgUHJpb3JpdHldIC0gQ3VzdG9tZXIgSW5jaWRlbnQgNjkxNzIgZm9yIEhhcmlkaGFyYW4gKDEzMjM5OSkgaGFyaWRoYXJhbnJAc3luY2Z1c2lvbi5jb20gOiBUZXN0aW5nIFRlc3RpbmcgVGVzdGluZyBUZXNpbmcgVGVzdGluZyBUZXN0aW5nIFRlc3RpbmcgVGVzdGluZyBUZXN0aW5nIFRlc3Rpbmcg4o"
This problem occurred in server only. 仅在服务器中发生此问题。 while debugging i have used the same subject content in my "local" but, i got correct subject.
在调试时,我在“本地”中使用了相同的主题内容,但是,我得到了正确的主题。
Program: 程序:
protected MailMessage msg;
msg.Subject = subject;
Got the same (error) subject in WebMail.IHostExchange.NET also. WebMail.IHostExchange.NET中也有相同(错误)主题。
What is the problem? 问题是什么?
This is a part of my coding. 这是我编码的一部分。
public EmailSenderThread(string emailAddresses, string ccemailaddress, string from, string subject, string body)
: base()
{
msgThread = new Thread(new ThreadStart(MailSender));
this.mailAddress = emailAddresses;
this.ccmailAddress = ccemailaddress;
msg.From = new MailAddress(from);
msg.IsBodyHtml = true;
msg.Body = body;
string[] mails = emailAddresses.Split(';');
foreach (string mail in mails)
if (!string.IsNullOrEmpty(mail))
msg.To.Add(mail);
if (ccemailaddress != string.Empty)
{
string[] ccemails = ccemailaddress.Split(';');
foreach (string ccmail in ccemails)
if (!string.IsNullOrEmpty(ccmail))
msg.CC.Add(ccmail);
}
msg.Subject = subject;
msgThread.Start();
}
I have already tried with 我已经尝试过
msg.SubjectEncoding = System.Text.Encoding.UTF8;
but i got the same error. 但我有同样的错误。 Did you got my doubt.
你有我的疑问吗? Please let me know if I didn't explain clearly.
如果我没有清楚说明,请告诉我。
1) why it is working fine in local? 1)为什么它在本地工作正常? and why it is not working when i am hosting this into server.
以及为什么当我将其托管到服务器时它不起作用。 ?
?
2) What is the maximum length of the subject line? 2)主题行的最大长度是多少?

From RFC822 about unstructured header fields: 来自RFC822中有关非结构化标头字段的信息:
Some field bodies in this standard are defined simply as "unstructured" (which is specified below as any US-ASCII characters, except for CR and LF) with no further restrictions.
该标准中的某些现场主体被简单地定义为“非结构化”(以下指定为任何US-ASCII字符,CR和LF除外),没有其他限制。 These are referred to as unstructured field bodies.
这些被称为非结构化现场主体。 Semantically, unstructured field bodies are simply to be treated as a single line of characters with no further processing (except for header "folding" and "unfolding" as described in section 2.2.3).
从语义上讲,非结构化的字段主体仅被视为单行字符,无需进一步处理(如2.2.3节中所述,标题“折叠”和“展开”除外)。
The subject line is an unstructured field, and therefore has no imposed length limit. 主题行是一个非结构化字段,因此没有强加的长度限制。
Without seeing more code, I'm going to guess an encoding problem - try specifying an encoding for your subject and body. 在没有看到更多代码的情况下,我将猜测一个编码问题-尝试为您的主题和身体指定编码。 Look at this post for sample code .
