试试这个

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。或者看看这篇较老的帖子： Adding a newline into a string in C#

Answer 3

你可以尝试这个+Environment.NewLine+

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

Answer 4

这是解决问题的示例，在我的代码段中的注释中尝试一次，您的答案。

ng-bind-html

Answer 5

根据你的意见，你需要这样的东西（你应该使用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起作用，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：

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