Using html page as mail body in asp.net

I have an emai开发者_C百科l template in a file called template.html, how can i use it as mail body in asp.net?

There's a sample here with code.

Or you could use the MailDefinition class.

You can use this:

File.ReadAllText("template.html")

//This is to read template.html then you can pass this through
//formatemail() function if you have or
//message.body = File.ReadAllText("template.html");
