考虑到SmtpClient有一个我没有使用的SendAsync方法,因此假设StmpClient.Send是同步的是否安全？我正在使用它来发送带有临时文件附件的电子邮件,并想知道我是否可以立即删除临时附件.
谢谢,罗布.
假设我使用smtpclient将我的电子邮件提交到我的本地smtp服务器.我如何知道电子邮件是否被正式发送？
试图在我的C#应用程序中发送一些电子邮件.我支持代理 - 这无疑是代码无效的原因.这是我到目前为止:
App.Config:
<system.net>
<defaultProxy enabled="false">
<proxy proxyaddress="xxx.xxx.xxx.xxx"/>
</defaultProxy>
<mailSettings>
<smtp deliveryMethod="Network">
<network host="smtp.gmail.com" port="587"/>
</smtp>
</mailSettings>
</system.net>
代码:
var username = "...";
var password = "...";
var fromEmail = "...";
var toEmail = "...";
var body = "Test email body";
var subject = "Test Subject Email";
var client = new SmtpClient("smtp.gmail.com", 587)
{
Credentials = new NetworkCredential(username, password),
EnableSsl = true
};
try
{
client.Send(fromEmail, toEmail, subject, body);
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
每次我得到System.Net.WebException:无法解析远程名称:'smtp.gmail.com' …
我正在构建一个发送电子邮件的Web应用程序SmtpClient.net应用程序工作正常,电子邮件成功发送到gmail帐户和hotmail帐户,但是当我发送电子邮件到yahoo帐户时它成功发送,但是我在邮件中放入的链接被雅虎禁用.雅虎以某种方式重写链接并完全删除"href"属性,我不知道该怎么做,我已经尝试了我所知道的每种格式,但这并不好.这是我用来发送消息的代码.
objEmail = new System.Net.Mail.MailMessage();
objEmail.To.Add(new MailAddress(contact.Value.ToString(),null));
objEmail.From = new MailAddress(from, null);
objEmail.Subject = subject;
objEmail.Body = Body;
objEmail.IsBodyHtml = true;
SmtpClient client = new SmtpClient();
client.Send(objEmail);
这是web.config文件中smtpclient的定义
<system.net>
<mailSettings>
<smtp deliveryMethod="Network">
<network enableSsl="true" host="smtp.gmail.com" password="password" userName="user@gmail.com" port="587"/>
</smtp>
</mailSettings>
</system.net>
在消息体中我放了一个简单的链接,
<a href="http://www.postagi.com/HomePage.aspx?id=101">tester</a>
这是雅虎在那里显示电子邮件收件箱.
<a id="yui_3_2_0_1_1327400481004292" rel="nofollow">tester</a>
这个错误真的让我发疯,请帮忙.
今天早上我发现了一些SmtpClient类(.net 3.5)的奇怪行为.无法解释是否是导致它的类,或SMTP服务器.
发生以下情况:
在前两种情况下,异常消息是:
信箱不可用.服务器响应为:5.7.1客户端无权作为此发件人发送"
问题:
提前致谢!!
我使用下面显示的Send方法随机获得异常.我得到的例外是:
Exception information:
Exception type: System.Net.Mail.SmtpException
Exception message: Failure sending mail.
Inner exception information (level 1):
Exception type: System.IndexOutOfRangeException
Exception message: Index was outside the bounds of the array.
我的方法如下所示:
public void Send(string from, List<string> to, string subject, string body, List<string> attachments)
{
var email = new MailMessage();
var server = new SmtpClient();
// Add each mail property
email.From = new MailAddress(from);
foreach (var t in to)
email.To.Add(t);
email.Subject = subject;
email.IsBodyHtml = true;
email.Body = body;
foreach (var a …我正在尝试使用以下代码通过gmail发送邮件,但我一直收到错误,指出"无法连接到远程主机".我已经仔细检查了我的配置,一切看起来都很好.有人看到我失踪的东西吗？
