在Code-Behind中从Web.Config中检索HTML

Question

Web.Config:

<appSettings>
    <add key="html1" value="This is &lt;br /&gt; HTML email"/>
</appSettings>

I'm trying to generate HTML formatted email. Prior to putting data in Web.Config I had both text and HTML emails formatted correctly.

In code-behind:

StringBuilder emailMessageString = new StringBuilder();
emailMessageString.Append(WebConfigurationManager.AppSettings["html1"].ToString());

Output in HTML email:

This is <br /> HTML email

Expected output in HTML email:

This is

HTML email

UPDATE - 02-19-2015

It looks like code I wrote to generate HTML email is not working correctly and had previously posted the code in this question (in my own answer). Can someone spot what I'm doing wrong as it looks like only the text emails are working:

Answer 1

You do not need to decode again. This should solve it -

var body = new StringBuilder();
body.Append(WebConfigurationManager.AppSettings["html1"]);

Also, ensure that you set IsBodyHtml to true.

var message = new MailMessage();
message.IsBodyHtml = true;

Hello Brother you can use Server.HtmlDecode(string s)

see below code

StringBuilder emailMessageString = new StringBuilder();
emailMessageString.Append(Server.HtmlDecode(WebConfigurationManager.AppSettings["html1"].ToString()));
