How to send email in C #
First, create an interface (Webform1.aspx)
Type Object Name Text Property Label Label1 Recipient Address: Label Label2 Title: label Label3
TextBox TextBox1
Textbox textbox2
TextBox TextBox3
Button Button1 Send RegulaRexpressionValidator RegulaRexpressionValidator1
be careful:
1. When sending a successful object Label3's text attribute shows "Send Success"
2. Object RegularExpressionValidator1 properties
ControlTovAlidate = "TextBox1"
ErrorMessage = "email format is wrong"
ValidationExpression = "/ w ([- .] / W ) * @ / w ([-.] / W ) * /. / W ([-.] / W ) *" // represents Email Verification format
When the address format of the recipient's email is incorrect, "email format is wrong"
3. Object TextBox1 Represents Recipient Address
Object TextBox2 represents title
Object TextBox2 representative send content
Second, display code (Webform1.aspx.cs)
1. Add code Using System.Web.mail in the file header;
2. Add Field Private System.Web.mail.mailMASSAGE M_MAIL;
3.
Private Void Page_Load (Object Sender, System.EventArgs E)
{
m_mail = new mailmessage (); // instantiate the MailMessage object
}
4. Double-click the "Send" button
Private void Button1_Click (Object Sender, System.Eventargs E)
{
m_mail.from = "jinq@gpssz.com";
m_mail.to = textbox1.text;
M_mail.subject = textbox2.text;
m_mail.bodyformat = mailformat.html;
m_mail.body = textbox3.text;
SMTPMAIL.SEND (m_mail);
Label3.Text = "Send success";
}
This is achieved throughout the function, thank you for
