如何使用C#在電子郵件中發送格式化的文本?

[英]How do I send formatted text in email using C#?

以下是我發送電子郵件的代碼段:


            MySqlCommand cmdsd;
            MySqlConnection conn;
            string s23 = "";
            conn = new MySqlConnection("server=localhost;database=projecttt;uid=root;password=techsoft");
            conn.Open();

             //smtp which will be loaded is webmail.techsofttechnologies.com
            cmdsd = new MySqlCommand("select smtp from smtp", conn);
            MySqlDataReader dr45 = cmdsd.ExecuteReader();

            while (dr45.Read())
            {
                s23 = dr45.GetString(0).Trim();
            }
            string s1 = textBox3.Text;
            string s4 = textBox1.Text;
            string S5 = textBox2.Text;
            string attachment = textBox5.Text;
            MailMessage mail = new MailMessage();
            mail.From = new MailAddress(s4, S5);
            mail.BodyEncoding = Encoding.UTF8;                
            mail.To.Add(s1);
            mail.Subject = textBox4.Text;
            mail.Body = "<body>"+textBox6.Text+"</body>";                
            //mail.Body = textBox6.AppendText("\n");

            AlternateView planview = AlternateView.CreateAlternateViewFromString("This is my plain text content, viewable tby those clients that don't support html");
            AlternateView htmlview = AlternateView.CreateAlternateViewFromString("<b>This is bold text and viewable by those mail clients that support html<b>");
            mail.IsBodyHtml = true;
            mail.Priority = MailPriority.High;
            System.Net.Mail.Attachment jil = new System.Net.Mail.Attachment(attachment);
            mail.Attachments.Add(jil);
            SmtpClient smtp = new SmtpClient(s23);
            try
            {
                smtp.Send(mail);
            }

            catch (Exception ex)
            {
                Exception exc = ex;
                string Message = string.Empty;
                while (exc != null)
                {
                    Message += exc.ToString();
                    exc = exc.InnerException;
                }
            }
            conn.Close();
            this.Close();
        }
        catch (Exception err)
        {
            MessageBox.Show(err.Message);
        }

    }

郵件正文包含帶換行符的文本。

但是我無法格式化文本。 在郵件中,它顯示為連續的行,並用空格代替換行符。

如何使它按預期工作?

您可能需要將換行符轉換為正確的HTML換行符:

text.Replace("\n", "<br/>")

對於電子郵件的HTML版本,您將需要用<br />標記替換換行符。 一個簡單的string.Replacestring.Replace應該做到這一點。

對於純文本電子郵件,我想您的電子郵件已按照需要進行格式化,並且您正在使用Outlook接收電子郵件。

Outlook有助於刪除它認為是額外的空格(通常是任何空格)的內容。 有一個選項可以將其關閉,通常在完全打開郵件時會在窗口頂部顯示該選項。

要將其完全關閉以用於Outlook:

工具 > 選項 > 首選項 > 電子郵件選項 ...>取消選中在純文本消息中刪除多余的換行符

大家好,

感謝您提供的所有幫助。

我在以下鏈接中得到了答案

基本上,替換功能將給出答案。

完整的答案如下:


            //The text will be loaded here
            string s2= textBox6.Text;     

            //All blank spaces would be replaced for html subsitute of blank space(&nbsp;) 
            s2 = s2.Replace(" ", "&nbsp;");          

            //Carriage return & newline replaced to <br/>
            s2=s2.Replace("\r\n", "<br/>");                
            string Str = "<html>";
            Str += "<head>";
            Str += "<title></title>";
            Str += "</head>";
            Str += "<body>";
            Str += "<table border=0 width=95% cellpadding=0 cellspacing=0>";
            Str += "<tr>";
            Str += "<td>" + s2 + "</td>";
            Str += "</tr>";
            Str += "</table>";
            Str += "</body>";
            Str += "</html>";                        
            mail.Subject = textBox4.Text;                          
            mail.Body = Str;
