如何在 mailmessage.body 部分提供新行

Question

I have sent mail using SMTP (ASP.NET).

I have written text in one line only, but I want to be in next line.

I used \\n , but it's not working.

Answer 1

System.Environment.NewLine

If you format your email as HTML you can add a <br /> to it.

To format as HTML use the IsBodyHtml property of the MailMessage class.

Answer 2

if IsBodyHtml == false, then https://social.msdn.microsoft.com/Forums/vstudio/en-US/82da38ac-ac20-4c9a-a2bd-8512d88fdd41/c-newline-in-email?forum=csharpgeneral suggests:

Use %0D%0A to separate lines.

To simplify, use “\\r\\n”, then call Uri.EscapeDataString for body and subject before concatenation.

if IsBodyHtml == true, as suggested above, use <br /> You can use someText.Replace("\\n", "<br />" ) to replace newlines (any remaining \\r from \\r\\n line endings will be ignored). Or use someText.Replace("\\r\\n", "<br />" ).Replace("\\n", "<br />" ) to fix both line endings without any \\r remainders, if line-endings are intermixed in text.

Answer 3

I solved the problem this way :

Replace \\n by \\t\\n

The tab will not be shown, but the newline will work.
