Hello friends..
I am creating a page in asp.net to send mails, where Credentials (''userid''and ''password'') and From are should be different.

for example:
if I am sending mail using creadentials,
UserID: [e-mail]
password:123456

then

mail received by recipient should appear as

From : [e-mail]
To : [e-mail]
Subjet: Hi
Message: Hello Dear..

Please notice the ''From : ''

Please help..
Here is the code that I am using...

System.Net.NetworkCredential _Credential = new System.Net.NetworkCredential(UserID, Password);
            System.Net.Mail.MailMessage _MailMessage = new MailMessage();
            _MailMessage.To.Add(txt_email.Text);
            _MailMessage.Subject = subject;

            _MailMessage.From = new System.Net.Mail.MailAddress(<big>From</big>);
            _MailMessage.Body = message;
            _MailMessage.IsBodyHtml = true;
            System.Net.Mail.SmtpClient _SmtpClient = new System.Net.Mail.SmtpClient(smtp);
            _SmtpClient.UseDefaultCredentials = true;
            _SmtpClient.EnableSsl = true;
            _SmtpClient.Credentials = _Credential;
            _SmtpClient.Port = Convert.ToInt32(port);
            _SmtpClient.Send(_MailMessage);

            lbl_Err.Text = "Mail Sent Successfully!";
            lbl_Err.ForeColor = System.Drawing.Color.Green;
            lbl_Err.Visible = true;

推荐答案

设置发件人"地址时，会有一个替代项允许您使用:

When you set the From address, there is an override which allows this:

mail.From = new MailAddress(fromAddress, fromDisplay, Encoding.UTF8);

如果您在这里看看，这里有个技巧为整个过程提供了一种通用方法:

If you have a look here there is a Tip which provides a generic method for the whole process: Sending an Email in C# with or without attachments: generic routine.[^]

默认情况下，电子邮件发送时带有 System.Web.Mail 的格式为纯文本.若要将格式设置为HTML，请将 MailMessage.BodyFormat 属性设置为 MailFormat.Html .

例如:

By default, email sent with System.Web.Mail is formatted as plain text. To format as Html, set the MailMessage.BodyFormat property to MailFormat.Html.

ex:

mail.BodyFormat = MailFormat.Html;
mail.Body = "this is my test email body.<br><b>this part is in bold</b>";

尝试一下

MailAddress mailfrom = new MailAddress ( "[e-mail]" );
            MailAddress mailto = new MailAddress ( "[e-mail]" );
            MailMessage newmsg = new MailMessage ( mailfrom, mailto );
            newmsg.Subject = "Subject of Email";
            newmsg.Body = "Body(message) of email";
            ////For File Attachment, more file can also be attached
            Attachment att = new Attachment ( "G:\\code.txt" );
            newmsg.Attachments.Add ( att );
            SmtpClient smtps = new SmtpClient ( "smtp.gmail.com", 587 );
            smtps.UseDefaultCredentials = false;
            smtps.Credentials = new NetworkCredential ( "[e-mail]", "urpwd" );
            smtps.EnableSsl = true;
            smtps.Send ( newmsg );
