The mail sending function is used in a recent project. This is different from the method used to send emails for a previous project. Previously, information about the emails to be sent was inserted into a database table on the server. The database checks newly added records and sends emails. That is, I only need to insert records into a database. This email sending function uses the smtpclient in the Microsoft system. net. Mail namespace to send messa

Today, I sent a mail to the mailbox smtpclient. The MailServer on the shelf is normal, but the MailServer on the other side is lost. It is found that the mailbox certificate appears, but the Outlook mail is normal, if no result is found, use the wireshark to check whether the smtpclient is different from the one sent by outlook. Finally, use reflector to find out how to set the authentication method. This

. Net has greatly improved the mail. smtpclient function since 2.0. It is easy to send emails. However, the US lacks the ability to save the email content as an EML file. In fact, smtpclient and mailmessage have implemented this function, but this function is nonpublic and invisible outside the space. Use reflector to decompile system. net. Mail. smtpclient. You

　　Objective　　There are many ways to send mail, such as sending mail via the. Net Framework's built-in SmtpClient, using an open source project Lumisoft.net, and so on, and here's how to use SmtpClient under the System.Net.Mail namespace to send mail.　　First, the Mail sending process　　For example, a use 163 mailbox to send mail to B (QQ mailbox). First, a will mail through the SMTP (Simple Mail Transfer Prot

The procedure is this: Copy Code code as follows: static void Main (string[] args) { SmtpClient client = new SmtpClient (); Client. Host = "localhost"; MailAddress from = new MailAddress ("from@test.com"); MailAddress to = new MailAddress ("to@test.com"); MailMessage message = new MailMessage (from, to); Client. Send (message); Console.ReadLine (); } The

ASP. NET series: SmtpClient and asp. netsmtpclient for unit testing When SmtpClient is used to send an Email, we can create an ISmtpClient interface and a SmtpClientWrapper adaptation class. In the unit test, we can perform Mock or custom FackeSmtpClient for ISmtpClient, however, the Facke SMTP Server of nDumbster provides us with a more intuitive and simple way to perform unit tests. You can search for nDu

Note: Two namespaces need to be introduced. Using system. net. mail;Using system. net; Procedure: Private void button2_click (Object sender, eventargs E){Application.

In the previous mailmessage saved as an EML file (C # + smtpclient), we used the Reflection Method to call system. net. mailwriter, the internal object of mail, implements saving mailmessage content as an EML file. Through the previous implementation, I learned how to use reflection and played a role in attracting others. Today, I occasionally saw the last code and found anotherNew WorldTo save the EML file, it becomes very simple. First, go back to t

Use the smtpclient class to send simple text emails, but cannot send emails containing attachments.To a receiver, it is a built-in JDK package, so it is more universal.The javamail package provides excellent functions to write any powerful email.System.

For the first time, I used this method to send an email. For example, I used my live mailbox to send an email to my QQ mailbox. The steps for sending an email using smtpclient will not be discussed. You can find too many information on the Internet. Here are some notes: If the email content is HTML, set mailmessage. isbodyhtml to true so that the email can be correctly read in HTML format. The reference resource in HTML uses CID: XXX. XXX is the cont

When sending email using smtpclient, we can create ismtpclient interfaces and Smtpclientwrapper adaptation classes, mock or custom fackesmtpclient ismtpclient in unit tests, But Ndumbster's Facke SMTP Server provides us with a more intuitive and straightforward way to unit test.

Refer to my blog post for a souvenir, especially the hash code-use SMTP to send emails in. net. Reference and sort out chinafcl In smtpclient, only the email address, password, and SMTP server address are provided. How can I test whether the email address and password are correct? (Similar to the test connection function of the mail client) Private bool checksmtp (string smtpserver, int port, string username, string password){Tcpclient = new tcpclient

. NET since 2.0, has greatly improved the function of mail.smtpclient, for the e-mail, can be very comfortable. However, the drawback is not to provide the ability to save the content of the message as a EML file In fact, SmtpClient and MailMessage have implemented this function, but this function is nonpublic, for the space outside, not visible. Using Reflector to decompile the System.Net.Mail.SmtpClient you can see: In the Send (MailMessage) me

In the previous MailMessage save as a eml file (c#+smtpclient), we used the Reflection (Reflection) method to invoke the System.Net.Mail internal object Mailwriter implemented the MailMessage is saved as a eml file. Through the last implementation, mainly to learn reflective reflection use of ideas, play a role in it, is Today, occasionally saw the last code, and found a new continent, so that the work of saving the eml file, become unusually simple

We can see that the outlook API is called in C # To initiate a meeting. This can be fully implemented using SMTP. The code used in my project is as follows: For. net, it is very easy to send emails from 2.0. In addition,Alternateview,You can use the
