Html encoding in .NET class library

Question

I have a utility class for sending emails. The emails are generated as html.

I'm having problems with encoding special characters which aren't getting displayed correctly.

However, I can't work out how to use HtmlEncode as I don't have a current HttpContext . Is there a .Net class which will translate special characters to html codes without running under Asp.Net ?

I hope that makes sense, I'm a bit flaky about how all this stuff works. Thanks!

Answer 1

I believe System.Net.WebUtility.HtmlEncode will provide this functionality. MSDN reference for WebUtility.HTMLEncode

Answer 2

You can import the System.Web namespace and use the HttpUtility class. Altohugh it's a Web assembly I don't think it's neccesary to be running under a Web environment for it to work.

Answer 3

您可以使用System.Web中的HttpUtility类。

Answer 4

You should really look into using the AntiXSS library of the WPL .

1. You don't need System.Web!

2. It uses a white-list inclusion principle ( System.Web encoding uses black-listing ). Only characters that are known to be safe will be trusted and all others will be properly encoded

Answer 5

HttpUtility.HtmlEncode怎么样 ？
