Question

mail.Body = "your appointment has been scheduled on :" + txtappointment.Text + " " + txtmessage.Text; 

Answer 1

試試這個

mail.Body ="your appointment has been scheduled on :"+ <br> + txtappointment.Text +" "+ txtmessage.Text; 

Answer 2

對於你應該使用\n一個新的生產線。或者看看這個較早的帖子： Adding a newline into a string in C#

Answer 3

你可以試試這個+Environment.NewLine+

mail.Body ="your appointment has been scheduled on :"+ <br> + txtappointment.Text +System.Environment.NewLine+ txtmessage.Text; 

Answer 4

這是實例用解決你的問題，嘗試了一次，你的答案評論在我的片段。

//mail.Body ="your appointment has been scheduled on :"+ txtappointment.Text +"\n"+ txtmessage.Text; 
 
var Fname = "samudrala"; 
 
var Lname = "Raamu"; 
 
alert(Fname+"\n"+Lname);

Answer 5

根據你的意見，你需要這樣的事情（和你應該使用string.Format方法，便於串管理：

mail.Body = string.format("your appointment has been scheduled on: {0}<br/>{1}", txtappointment.Text, txtmessage.Text); 

你可以看到你的文本編輯器的文本佔位符，第一個是預約，第二個是預約，對於html的工作，你必須設置IsBodyHtml這個標誌：

mail.IsBodyHtml = true; 

如果您的電子郵件客戶端不支持HTML或你不希望它是HTML中，使用Environment.NewLine不變，爲@AsifuzzamanRedoy建議，像這樣：

mail.Body = string.format("your appointment has been scheduled on: {0}{2}{1}", txtappointment.Text, txtmessage.Text, Environment.NewLine);
