通过 System.Net.Mail C# 发送邮件时出现问题

发布于 2024-07-14 15:08:00 字数 908 浏览 7 评论 0原文

这是我的邮件发送代码。我收到“邮件标题中存在无效字符”错误。当我更改计算机名称时，使用了一些最短的名称。问题解决了。但在我的域中，整个计算机名称如“04500-ab04545.xxxdomain.gov.tr”，所以我需要找到另一个解决方案来解决这个问题。

因此，我在从 C# 代码发送邮件时无法给出静态计算机名称。

 MailMessage msg = new MailMessage();
 msg.Body = "axxxxxx";
 msg.To.Add(new MailAddress("[email protected]"));
 msg.From = new MailAddress("[email protected]","blab blalb");
 msg.Subject = "Subject xxx";
 SmtpClient server = new SmtpClient("xxxxxxxx",25);
 server.Credentials = new NetworkCredential("xxxxx", "xxxxxxx");
 SmtpClient server = new SmtpClient("mail.adalet.gov.tr",25);
 server.Credentials = new NetworkCredential("xxx", "xxx");
 server.Send(msg);

This is my mail sending code. I was getting "There is Invalid character in Mail Header" error.When i changed my Computer Name some shortest name. The problem solved. But in my domain whole computer names like "04500-ab04545.xxxdomain.gov.tr" so I need to find another solution for this problem.

So I cant give a static computer name while sending mail from c# code.

 MailMessage msg = new MailMessage();
 msg.Body = "axxxxxx";
 msg.To.Add(new MailAddress("[email protected]"));
 msg.From = new MailAddress("[email protected]","blab blalb");
 msg.Subject = "Subject xxx";
 SmtpClient server = new SmtpClient("xxxxxxxx",25);
 server.Credentials = new NetworkCredential("xxxxx", "xxxxxxx");
 SmtpClient server = new SmtpClient("mail.adalet.gov.tr",25);
 server.Credentials = new NetworkCredential("xxx", "xxx");
 server.Send(msg);

我怀疑这可能是与编码相关的问题。

尝试使用 new MailAddress("[电子邮件受保护]", "blab blalb", Encoding.Default) 构造函数。

或者尝试Encoding.Unicode。

更新：

经过一番挖掘，此异常是从以下位置抛出的：

void System.Net.BufferBuilder.Append(string,int,int);

如果电子邮件地址中的 \xff 上方有任何字符，则会发生这种情况。这不应该发生，因为名称应该已经被编码，但我猜还有其他事情变得有趣。

I suspect this might be an Encoding related issue.

Try using the new MailAddress("[email protected]","blab blalb", Encoding.Default) constructor.

Else try Encoding.Unicode.

Update:

After some digging, this exception is thrown from:

void System.Net.BufferBuilder.Append(string,int,int);

This will happen if you have any characters above \xff in the email address. This is not suppose to happen, as the name should be encoded already, but something else is going funny I guess.

消息试图发送哪些标头？

您可以使用以下 MSDN 片段轻松转储：

string[] keys = message.Headers.AllKeys;
        Console.WriteLine("Headers");
        foreach (string s in keys)
        {
            Console.WriteLine("{0}:", s);
            Console.WriteLine("    {0}", message.Headers[s]);

What headers are the message trying to send with?

You can easily dump with this MSDN snippet:

string[] keys = message.Headers.AllKeys;
        Console.WriteLine("Headers");
        foreach (string s in keys)
        {
            Console.WriteLine("{0}:", s);
            Console.WriteLine("    {0}", message.Headers[s]);
