保持在 asp.net 文本框中输入的格式(回车、换行等) [英] keep formatting entered in asp.net textbox (carriage return, new line, etc)

问题描述

我有一个使用多行模式的文本框，当我创建用于更新的存储过程参数时，我在文本框值上使用了 Server.HtmlEncode.我可以将数据记录中的内容复制到记事本中，它会显示用户为新段落按下 Enter 键的空格.

I have a textbox using multiline mode and when I create the stored procedure parameter for updating I use Server.HtmlEncode on the textbox value. I can copy the content from the data record into Notepad and it shows the spaces where the user has pressed the Enter key for new paragraphs.

当在页面上显示该内容时(不是用于编辑的文本框；只是将内容分配给 Literal 控件)，它会将所有文本放在一起.

When displaying that content on a page (not a textbox for editing; just assigning the content to a Literal control), it has all the text run together.

我已经做了一些关于使用替换和不同转义序列或 Environment.NewLine 的搜索.我仍然对如何在用户输入时显示文本感到困惑.

I have done some searches about using Replace and different escape sequences or Environment.NewLine. I am still confused about how to have the text display as the user entered it.

推荐答案

假设您使用的是 C#，您可以在页面上显示字符串时执行以下操作

Assuming you're using C# you can do the following when you display the string on the page

theStringYouWantToFormat.Replace(char.ConvertFromUtf32(13),"<br/>")

当您对从文本框中获取的值调用 Server.HtmlEncode 时，它会查看文本并对包含在该文本框中的任何 HTML 标记进行编码，例如 <script></script> 将被编码为 <script></script>.

When you call Server.HtmlEncode on the value you grab from a text box it'll look at the text and encode any HTML tags contained in that text box so for example <script></script> would be encoded to <script></script>.
