如何在 txtmessage.Text 之前添加换行标记？

Question

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

Answer 1

尝试这个

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

Answer 2

对于新行，您应该使用\\n 。 或者看看这篇旧帖子： 在 C# 中将换行符添加到字符串中

Answer 3

你可以试试这个+Environment.NewLine+

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

Answer 4

这是您的问题解决方案的示例，尝试一次，您的答案在我的代码段中的评论中。

 //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

根据您的评论，您需要这样的东西（并且您应该使用string.Format方法来轻松管理字符串：

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

您可以看到文本编辑器文本的占位符，第一个用于约会，第二个用于消息。 要使 html 正常工作，您必须为此设置IsBodyHtml标志：

mail.IsBodyHtml = true;

如果您的电子邮件客户端不支持 html 或者您不希望它是 html，请使用Environment.NewLine常量，如@AsifuzzamanRedoy 建议的那样，如下所示：

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