Answer 4

这是实例用解决你的问题，尝试了一次，你的答案评论在我的片段。

//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

根据你的意见，你需要这样的事情（和你应该使用string.Format方法，便于串管理：

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编辑器的文本占位符，第一个是预约，第二个是预约，对于html的工作，你必须设置IsBodyHtml这个标志：

mail.IsBodyHtml = true; 

如果您的电子邮件客户端不支持HTML或你不希望它是HTML中，使用Environment.NewLine不变，为@AsifuzzamanRedoy建议，像这样：

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