c# - 在 Textarea 文本中添加或段落

Question

我正在使用文本框允许用户输入他们想要的任何文本，然后我通过电子邮件发送此文本。我想添加段落或
textarea 文本，例如，如果用户输入这个

this is test this is test this is test this is test this is test this is test
this is test this is test this is test this is test this is test

然后电子邮件将在一行中显示整个文本，我希望它看起来像两三个段落这样的

<p> this is test this is test this is test </p>
<p> this is test this is test this is test </p>

我如何在 C# 中做到这一点
