C＃Email - 不使用空格渲染的新行：预换行

Question

I have an email with a table and one value contains a string with multiple lines. (enter-key) When viewed in outlook or view source in IE, the white-space is not working.

Any idea or any solution?

Thanks.

Answer 1

This is related to Outlook (not C#). I have the same problem (using Java to send mail). I am using CSS style white-space:pre-wrap; on a span and it works well to preserve tabs, spaces, new lines and wrap text in GMail - web, Android and iOS.

As per my experimentation on Outlook 2016 Windows app and webapp (outlook.office365.com):

• Value pre-wrap does not preserve new lines in both Windows app and webapp
• Value pre preserves new lines in Windows app, but does not do so in webapp

Answer 2

New lines within html are not rendered as such. You need to add <br> tags at the end of each line to make sure that the email is rendered correctly with the new lines.

You can do this within your c# code by replacing every new line character in your problematic value with <br> .
